      Author(s): Abdullah S. AlSwuailem , Majed K. AlShehri , Salwa Al-Sadhan
      Objectives To assess the smoking prevalence among dental students at King Saud University (KSU) and determine possible risk factors for tobacco use among dental students. Methods A self-addressed invitation letter was sent to all dental students (males and females) at KSU requesting participation in this study. Data on smoking habits and associated risk factors as well as demographic factors, such as age, marital status, residency status, the student’s study year and grade point average were collected using an electronic self-administered questionnaire. This survey was sent via email to students who volunteered to participate. Data was analyzed using SPSS. Significant differences between different groups were assessed using Pearson Chi-Square test at α=0.05. Logistic regression analysis was used to calculate the odds ratio (OR) and 95% confidence interval (95% CI) and determine the effect of different risk factors on students smoking habits. Results There was a 67% response rate which represented 400 out of the 600 registered dental students (230 males, 170 females). The prevalence of students who were current smokers was significantly higher among male dental students (27.6%) compared to female dental students (2.4) (p<0.001). The majority of current dental smokers were using shisha tobacco only (N=35, 51.5%), followed by both shisha tobacco and cigarettes (N=17, 25%) and cigarettes only (N=16, 23.5%).Male dental students were about 4 times more likely to be smokers if all or the majority of their friends were smokers compared to students who had some friends who smoked (OR = 3.9, 95% CI = 1.9-7.7). A high proportion of current smokers (47.8%) reported stress as the main reason for smoking. Twenty-six percent of dental students (N=87) who are currently non-smokers reported that they have used tobacco at one point in their lives. Over two-thirds of the sampled students (63%) believed that public tobacco usage is not well addressed in the current college curriculum. Conclusions Approximately, one in every four male dental students at KSU is a smoker. Having friends who are smokers was the most important risk factor associated with dental students who smoke. There is a general belief among dental students that public tobacco use is not well addressed in dental college curriculum.

  • Knowledge, Attitudes And Experience Of Dentists Living In Saudi Arabia
           Towards Child Abuse And Neglect

    • Abstract: Publication date: Available online 9 May 2014

      Author(s): R. Al-Dabaan , JT. Newton , K. Asimakopoulou
      Aim To analyze the experience and knowledge of dental practitioners in Saudi Arabia regarding the identification of child abuse and neglect (CAN), to identify barriers that prevent the reporting of suspected cases of child maltreatment by dental practitioners, and to assess the need for training dentists in child protection. Method A self-administered, web-based questionnaire was emailed to all of the members of the Saudi Dental Society (n = -). Results The respondents (n = 121) demonstrated good knowledge of the forms and indicators of CAN. Moreover, a large proportion (59%) had experienced a case of child abuse or neglect in their practice over the previous five years. However, only about 20% of the respondents reported taking action in response to their suspicions. Fear of family reprisal, lack of certainty about the diagnosis of child maltreatment, and uncertainty about case management were critical barriers to the reporting of the suspected child maltreatment. In addition, only 20.9% of the respondents reported having knowledge of a child protection policy in their workplace. Conclusions Based on the results of this survey, it appears that the level of knowledge amongst the respondents regarding the forms and indicators of CAN is good. However, a large proportion of respondents did not take action regarding suspected cases of CAN in their practice over the past five years. Therefore, additional resources and training are needed to support the identification and management of cases of child maltreatment by dental practitioners.

  • The effect of laterally positioned flap-revised technique and 24% EDTA
           root conditioning on root coverage: A case report

    • Abstract: Publication date: Available online 6 May 2014
      Source:The Saudi Dental Journal
      Author(s): Jagmohan Singh , Vipin Bharti
      Complete root coverage is considered the true goal of treatment of gingival recession defects because only complete coverage assures recovery from the hypersensitivity and esthetic defects associated with recession areas. Previous studies have shown that the laterally positioned flap (LPF) technique or root surface biomodification yield a higher percentage of complete root coverage upon gingival recession treatment. This article highlights the use of the laterally positioned pedicle flap-revised technique (LPFRT) as a modification of the LPF technique, along with 24% EDTA gel as a root surface biomodification agent, in the management of localized gingival recession defects. Clinical examination revealed a Miller class II recession defect on the buccal aspect of the lower right central incisor, as well as the presence of aberrant frenum pull adjacent to the recession defect. The LPFRT, together with 24% EDTA gel, was speculated to cover the gingival recession defect. The frenectomy, along with periosteal fenestration, was planned simultaneously with LPFRT. After 6 months of therapy, the clinical condition was stable with complete root coverage and satisfactory healing of the gingival tissues at both the donor and recipient sites with no signs of inflammation.

      Objective To study the correlation between the position of the inferior dental (ID) nerve canal and the angulation of impacted mandibular third molars using dental cone beam computed tomography (CBCT). Materials and methods The study considered 100 impactions in 85 patients (60 males, 25 females), for whom an initial panoramic radiographic assessment had revealed that the ID canal and the lower 3rd molar were in close proximity. A CBCT scan of each patient was carried out to assess how the ID nerve canal position influenced the class and position of impaction, angulation of impaction, and bone contact. Results Class I position B impactions were found in the majority of cases, where the position of the ID canal was approximate to the lingual plate and inferior to the 3rd molar (85.7%). The results were statistically significant (p =0.001). 96% of the ID canals showed bone contact. Of these, 77.1% of ID canals exhibited lingual bone contact, inferior to impaction. The results were statistically significant (p =0.001). Horizontally angulated impactions were most common in the mandible, and significantly associated with lingual and inferior positioning of the ID canal (76.2%). Conclusions Our sample population most commonly exhibited horizontally angulated class I position B impactions of the mandible. The position of the ID canal significantly influenced the type of impaction and bone contact.

  • Attitude and Awareness of Dentist Towards Resin Bonded Bridges in Saudi
           Arabia

    • Abstract: Publication date: Available online 5 May 2014
      Source:The Saudi Dental Journal
      Author(s): Fahim Ahmed Vohra , Muhammed Ayedh Al-Qahtani
      Statement of the Problem Resin bonded bridges (RBBs) offer a conservative approach to tooth replacement. However, the use of this approach has been limited. Therefore, the aim of this study was to assess the knowledge and attitude of dentists in Saudi Arabia, including general dental practitioners (GDPs) and prosthodontic and restorative specialists (SPs), towards RBBs. Methods In this cross-sectional study, questionnaires designed to survey knowledge of RBB performance factors were distributed to GDPs and SPs (n = 400). Specifically, opinions of GDPs and SPs regarding clinical, mechanical, technique- and patient-dependent performance factors of RBBs were obtained. Average significance and Chi-square tests were used to identify the frequency, pattern, and significance of the response variables identified. Results A majority (65.3%) of the subjects reported using RBBs in less than 10% of their prosthodontic cases. The most common reason for the limited clinical application of RBBs was perceived poor retention (23.45%). In addition, SPs regarded the influence of enamel structure, number of pontics, cement type, RBB design, and surface treatment as “very significant” factors with respect to RBB survival. Overall, a statistically significant difference was observed between the responses of GDPs and SPs regarding their knowledge of performance factors for RBBs. Conclusion In comparison to SPs, GDPs reported greater disagreement with current standards for RBB success factors. Moreover, 60% of SPs and 71% of GDPs used RBBs for less than 10% of their prosthodontic cases. Therefore, continuing education opportunities are needed for practicing dentists, and undergraduate students need to receive greater exposure to the clinical application of RBBs.

  • Agreement between Orthodontist’s and Patients’ Perception
           using Index of Orthodontic Treatment Need

    • Abstract: Publication date: Available online 4 May 2014
      Source:The Saudi Dental Journal
      Author(s): Tania Arshad Siddiqui , Attiya Shaikh , Mubassar Fida
      Objectives The primary objective of the study was to assess the agreement between orthodontist and patient perception regarding the Aesthetic Component of the Index of Orthodontic Need (IOTN-AC) at pre-orthodontic treatment levels. The secondary objective was to determine how well the subjective assessment of malocclusion (IOTN-AC) correlated with the normative Dental Health Component of the IOTN (IOTN-DC). Materials and Methods A cross-sectional analytical study was conducted on patients between the ages of 16-25, presenting for initiation of orthodontic treatment with no history of prior orthodontic treatment. The mean age of the total sample population was 19.50 ± 3.15 years. The mean age of the males was 19.05 ± 3.09 years and for females it was 19.75 ± 3.18 years. The sample consisted of 41 males and 80 females. Patients were shown their pretreatment monochrome intraoral frontal photographs to rate according to the IOTN-AC. Simultaneously, the orthodontist reviewed the photographs with each patient. The IOTN-DHC of pretreatment casts was also recorded by the orthodontist. The frequency of specific traits that had led to increased severity of malocclusion was also identified. All readings were recorded manually on a data collection form. The data were assessed using the chi-square test, Spearman’s correlation and Cohen’s kappa test. Intra- and inter-examiner reliability was assessed using Spearman’s correlation. Results A significant positive relationship (p < 0.05) was observed between orthodontist and patient perception (r = 0.516), orthodontist perception and the normative need (r = 0.430), and between the patients’ perception and the normative need (r = 0.252). A statistically significant level of agreement was observed between orthodontist and patient perception (kappa = 0.339, p ⩽ 0.001, 95% CI, 0.207 – 0.470) and between orthodontist perception and the normative need (kappa = 0.331, p ⩽ 0.001, 95% CI, 0.197 – 0.424). A weak and insignificant level of agreement was observed between patients’ perception and normative treatment need (kappa = 0.107, 95% CI, 0.02 – 0.187). Conclusions Patients’ understanding of their treatment need or aesthetic classification may not always be as accurate as that of orthodontists. This may be a cause for concern when an orthodontist finds a certain condition to be severe, and a patient who does not agree may limit their treatment needs.

  • Prevalence of Dental Caries Among 12 to 14 Year Old Children in Qatar

    • Abstract: Publication date: Available online 4 May 2014
      Source:The Saudi Dental Journal
      Author(s): Mohammed Al-Darwish , Walid El Ansari , Abdulbari Bener
      Background To ensure the oral health of a population, clinicians must deliver appropriate dental services, and local communities need to have access to dental care facilities. However, establishment of this infrastructure must be based on reliable information regarding disease prevalence and severity in the target population. Objectives The aims of this study were to measure the incidence of dental caries in school children aged 12-14 throughout Qatar, including the influence of socio-demographic factors. Materials and methods A cross-sectional study was conducted in Qatar from October 2011 to March 2012. A total of 2113 children aged 12-14 were randomly selected from 16 schools located in different geographic areas. Three calibrated examiners using World Health Organization (WHO) criteria to diagnose dental caries performed the clinical examinations. Data analyses were subsequently conducted. Results The mean decayed, missing, and filled teeth index values were respectively 4.62 (± 3.2), 4.79 (± 3.5), and 5.5 (± 3.7), for 12-, 13-, and 14-year-old subjects. Caries prevalence was 85%. The mandibular incisors and canines were least affected by dental caries, while maxillary and mandibular molars exhibited the highest incidence of dental caries. Dental caries were affected by socio-demographic factors; significant differences were detected between female and male children, where female children were at increased risk for dental caries. In addition, children residing in semi-urban areas were at higher risk for dental caries than children living in urban areas. Conclusion Results indicated dental caries prevalence among school children in Qatar has reached critical levels, and is influenced by socio-demographic factors. The mean decayed, missing, and filled teeth values obtained in this study were the second highest detected in the Eastern Mediterranean region.

      Papillon–Lefevre syndrome (PLS) is an autosomal recessive genetic disorder characterized by palmoplantar hyperkeratosis associated with severe early-onset periodontitis and premature loss of primary and permanent teeth. This report describes two cases of PLS in 28-year-old female and 16-year-old male siblings with consanguineously married parents. The patients presented to the Department of Public Health Dentistry of a dental education and research institute in India with thickening, flaking, and scaling of the skin on the palms and soles of the feet. On oral examination, the female patient presented completely resorbed maxillary and mandibular alveolar ridges with retention of only the third molars. The male patient retained only teeth 18, 13, 28, 38, and 45. Based on complete histories and clinical examination findings, a final diagnosis of PLS was made and treatment was initiated using an interdisciplinary dental approach in both cases.

  • Effect of honey in preventing gingivitis and dental caries in patients
           undergoing orthodontic treatment

    • Abstract: Publication date: Available online 19 April 2014
      Source:The Saudi Dental Journal
      Author(s): AL-Dany A. Atwa , Ramadan Y. AbuShahba , Marwa Mostafa , Mohamed I. Hashem
      Objectives This study was conducted to investigate the following: (1) the effects of chewing honey on plaque formation in orthodontic patients, (2) the effect of chewing honey on dental plaque bacterial counts, (3) determine if honey possesses antibacterial effects on bacteria recovered from plaques. Methods Female orthodontic patients (n =20, 12–18years of age) participated in this randomized controlled study. The effects of honey were compared to treatment with either 10% sucrose or 10% sorbitol that served as positive and negative controls, respectively. The pH of plaque was measured using a digital pH meter prior to baseline and at 2, 5, 10, 20, and 30min after chewing honey or rinsing with control solutions and the numbers of Streptococcus mutans, Lactobacilli, and Prophymonas gingivalis in respective plaques were determined. The antibacterial activity of honey was tested against commonly used antibiotics using the disk diffusion method. Results Significant differences in pH were observed in the honey and sucrose groups compared to the pH observed in the sorbitol group (P ⩽0.001). The maximum pH drop occurred at 5min in both the honey and sucrose groups; however the pH in the honey group rapidly recovered 10–20min after exposure and did not drop below the critical decalcification pH of 5.5. On the other hand, the pH following sucrose exposure fell <5.5 and was associated with a 30min recovery time. The pH observed for the sorbitol group did not change over time. Bacterial counts were significantly reduced in the honey group compared to the other treatment groups (P ⩽0.001) and honey significantly inhibited the growth of all studied strains compared to inhibition observed with antibiotics (P ⩽0.001). Conclusions Honey can be used as an alternative to traditional remedies for the prevention of dental caries and gingivitis following orthodontic treatment.

      Author(s): Diemah F. Alhekeir , Rana A. Al-Sarhan , Abdulmohsen F. Al Mashaan
      Objective To investigate the association of the failure of porcelain laminate veneers with factors related to the patient, material, and operator. Methods This clinical survey involved 29 patients (19 women and 10 men) and their dentists, including undergraduate and postgraduate dental students and dental interns. Two questionnaires were distributed to collect information from participants. All patients were clinically examined. Criteria for failure of the porcelain laminate veneers included color change, cracking, fracture, and/or debonding. Results A total of 205 porcelain laminate veneers were evaluated. All of the restorations were fabricated from IPS e.max Press and cemented with Variolink Veneer (Ivoclar Vivadent, Schaan, Principality of Liechtenstein) or RelyX veneer cement (3M ESPE, St. Paul, MN, USA). The preparations were generally located in enamel (58.6%), and most veneers had an overlapped design (89.7%). Ten patients (34.48%) showed veneer failure, most often in terms of color change (60%). Overall, 82.8% of patients were satisfied with their restorations. Conclusion Insufficient clinical skills or operator experience resulted restoration failure in one-third of patients.

      Author(s): Faiza A Qari
      Brown tumors are uncommon focal giant-cell lesions that arise as a direct result of the effect of parathyroid hormone on bone tissue in some patients that have hyperparathyroidism. Primary hyperparathyroidism could be caused by ectopic mediastinal parathyroid adenomas. The occurrence of lesions is explainable on embryologic basis. We present a 55-year-old Saudi woman with a rare case of brown tumor of the maxilla due to ectopic mediastinal parathyroid adenoma.

      Author(s): K.N. Al Shayeb , W. Turner , D.G. Gillam
      Aim The aim of the present study was to measure the accuracy and reproducibility of probe forces in simulated assessments of periodontal pocket depth. The study included experienced and inexperienced examiners and used manual and pressure-sensitive probes. Materials and Methods Sixty-one participants were divided into seven groups and asked to probe selected anterior and posterior sites with three different probes (Williams 14W, Chapple UB-CF-15, and Vivacare TPS probes). The model was positioned on a digital electronic balance to measure force, which was recorded initially and after 15 minutes. Probe preferences were recorded. Accuracy was measured by comparing to a standardized 25 g force, and reproducibility was calculated for all duplicate measurements. Results The Vivacare probe produced the most accurate and most reproducible forces, whereas the Williams probe produced the least accurate and least reproducible forces. Probe forces were lighter at anterior sites compared to posterior sites at baseline. Probe forces were reduced at both sites after 15 minutes compared to baseline. Conclusions Vivacare TPS periodontal probes are more accurate and reproducible than Chapple and Williams probes. Many clinicians in this study preferred the Chapple probe.

      Fractures of severely atrophic (height<10mm) edentulous mandibles are infrequent and challenging to manage. Factors such as sclerotic bone and decreased vascularity combined with systemic diseases complicate the management of such fractures. Osteogenesis imperfecta (OI) is a heterogeneous group of inherited disorders of type I collagen metabolism. Patients with OI characteristically present with histories of long bone fractures, deformities, blue sclerae, and opalescent dentin. However, fractures of the facial skeleton are rare. Bisphosphonate therapy has been proven to effectively reduce the fracture risk in patients with OI. The purpose of this clinical report is to present an unusual case of spontaneous fracture of the atrophic mandible in a patient with OI. Despite open reduction and internal fixation (ORIF) with miniplate osteosynthesis, the patient developed a second fracture at a screw placement site distal to the first fracture. The patient was successfully treated with ORIF using locking reconstruction plates fixed in the symphyseal and angle regions. Bone healing following ORIF was normal, and no clinical sign of osteonecrosis as a result of bisphosphonate therapy was observed. Patients with OI can present with spontaneous fractures of already weakened mandibles. Although such fractures can be managed with care using established protocols, further research is required to examine the effects of concomitant medication, such as bisphosphonates.

      Author(s): Abdul Aziz Abdullah Al-Kheraif
      Objective The purpose of this study was to compare the effects of mechanical polishing (MP) and chemical polishing (CP) on the average (mean) surface roughness (Ra) of heat-cured (HC) and light-cured (LC) denture base acrylic resins. Methods A total of 120 specimens (30×15×3mm) were prepared from one HC and one LC acrylic resin. To remove nodules and gross surface irregularities, all specimens were finished with a lathe-mounted small acrylic bur and 360-grit sandpaper. Ten finished specimens of each acrylic resin were randomly assigned to each of six polishing techniques: Resilit High-luster Polishing Liquid (RHPL), Universal Polishing Paste, Abraso-star K50, pumice, Jet Seal Liquid, or Acrypoint. MP was performed with an automatic polishing machine for 2min, under 50rpm and 500g of load. CP was performed by immersing the HC and LC specimens in preheated methyl methacrylate at 75±1°C for 10s. The surface roughness of the acrylic resin specimens was measured with a contact profilometer. The Ra values were analyzed by two-way analysis of variance, post hoc Scheffe test, and paired t-test (p ⩽0.05). Polished and tested acrylic resin surfaces were evaluated by scanning electron microscopy. Results MP was more effective than CP. The smoothest surface was obtained with the use of the RHPL on the LC (0.05±0.01μm) or HC (0.07±0.01μm) acrylic resin. Two-way ANOVA showed a statistically significant difference between MP and CP. Conclusions MP produced the smoothest surface of denture base acrylic resin. The mean surface roughness values after MP and CP were not influenced by the type of acrylic resin.

      Ocular trauma can be caused by road traffic accidents, falls, assaults, or work-related accidents. Enucleation is often indicated after ocular injury or for the treatment of intraocular tumors, severe ocular infections, and painful blind eyes. Rehabilitation of an enucleated socket without an intraocular implant or with an inappropriately sized implant can result in superior sulcus deepening, enophthalmos, ptosis, ectropion, and lower lid laxity, which are collectively known as post-enucleation socket syndrome. This clinical report describes the rehabilitation of post-enucleation socket syndrome with a modified ocular prosthesis. Modifications to the ocular prosthesis were performed to correct the ptosis, superior sulcus deepening, and enophthalmos. The rehabilitation procedure produced satisfactory results.

      Papillon-Lefevre syndrome (PLS) is a very rare, autosomal recessive syndrome characterized by palmar-plantar hyperkeratosis and severe destructive periodontitis. Most patients with PLS harbor mutations in the cathepsin C gene, but recent studies have identified individuals with classic PLS symptoms without such mutations. This suggests more genetic heterogeneity for PLS than previously thought. Here we present an individual manifesting characteristic clinical features of PLS with no mutations in the coding sequence of cathepsin C. We suggest there must be alternative genetic causes for such forms of PLS.

      Dental plaque is considered to be a major etiological factor in the development of periodontal disease. Accordingly, the elimination of supra- and sub-gingival plaque and calculus is the cornerstone of periodontal therapy. Dental calculus is mineralized plaque; because it is porous, it can absorb various toxic products that can damage the periodontal tissues. Hence, calculus should be accurately detected and thoroughly removed for adequate periodontal therapy. Many techniques have been used to identify and remove calculus deposits present on the root surface. The purpose of this review was to compile the various methods and their advantages for the detection and removal of calculus.

      Author(s): Nour M. Ajaj-ALKordy , Mohannad H. Alsaadi
      Background Fractures of acrylic resin dentures are a common occurrence in clinical dentistry. The denture may be fractured accidentally when dropped or while in service in the mouth due to flexural fatigue. Objectives The aim of this study was to compare the elastic modulus and the flexural strength between two heat-cured acrylic resins used in denture bases: a high-impact resin (Lucitone 199) and a traditional resin (Rodex). Material and methods Rectangular strips of Lucitone 199 and Rodex (10 samples each) were fabricated and stored in artificial saliva at 37 °C for 2 weeks. The specimens were subjected to a three-point flexural test. The data were statistically analyzed with Student’s t-test (p ⩽ .05). Result The high-impact acrylic resin had a lower elastic modulus (p = .000) and higher flexural strength (p = .001) compared to the traditional acrylic resin. Conclusion Within the limitations of this study, it can be concluded that the high-impact acrylic resin is a suitable denture base material for patients with clinical fracture of the acrylic denture.

  • A literature review on “low levels of caries in aggressive
           periodontitis”: A lesser known and lesser stressed factor

    • Abstract: Publication date: Available online 14 December 2013
      Source:The Saudi Dental Journal
      Author(s): S.R. Srinivas
      Aggressive periodontitis generally affects systemically healthy individuals aged < 30 years (older individuals can also be affected) and is characterized by a young age of onset, rapid rate of disease progression, and familial aggregation of cases. Dental caries is caused by the dissolution of enamel by acid-producing bacteria present in the plaque biofilm, especially when the biofilm reaches critical mass due to improper oral hygiene. The association between caries level and aggressive periodontitis has long been debated. Initial research indicated that caries levels were high in patients with aggressive periodontitis, but high-quality studies have consistently shown that caries and aggressive periodontitis are inversely related. Recent in vitro studies have shown that Streptococcus mutans was killed more readily in the saliva of patients with aggressive periodontitis and Aggregatibacter actinomycetemcomitans positivity. Other mechanisms possibly explaining the inverse relationship between caries and aggressive periodontitis are discussed in this literature review. The usefulness of caries level in the diagnosis of aggressive periodontitis is also discussed.

      Author(s): K.N. Al Shayeb , W. Turner , D.G. Gillam
      Aim The purpose of the present in vitro study was to measure the accuracy and reproducibility of three periodontal probes. To eliminate environment- or examiner-related probing errors, two aluminum blocks with predrilled holes of varying depths were examined by participants who had been trained in probing before the study. This methodology improved the likelihood that any probing errors identified were generated by the probes themselves. Material and Methods Three probes, Williams 14W (Hu-Friedy Mfg. Co., LLC, UK), Chapple UB-CF-15 (Implantium, Shrewsbury, UK), and Vivacare TPS (Ivoclar Vivadent, Enderby, UK), were randomly distributed to 23 participants (9 males; mean age: 31.35 years). Participants measured 30 holes in two aluminum blocks, and then repeated the exercise after an interval of 1 week to 3 months. For each hole, the mean measured depth was calculated for each participant and compared to the true depth. Intra- and inter-examiner accuracy and reproducibility for each of the duplicate measurements were calculated. Data were analyzed by paired-samples t-test with the SPSS 18 software package (IBM Portsmouth, UK). A p-value < 0.05 indicated statistical significance. Tables were constructed from the data. Results When used by participants, the Williams 14W probe was reproducible but not necessarily accurate; Vivacare TPS was neither accurate nor reproducible; and Chapple UBCF-15 was both accurate and reproducible. Conclusions Depth measurements with the Chapple UB-CF-15 probe were more accurate and reproducible compared to measurements with the Vivacare TPS and Williams 14W probes. This in vitro model may be useful for intra-examiner calibration or clinician training prior to the clinical evaluation of patients or in longitudinal studies involving periodontal evaluation.

      Background Oral mucositis is the most common side effect of cytotoxic therapy of cancer. Aims of the study The objectives of this study were to assess the effect of a mouth rinse containing olive leaf extract (OLE) in preventing severe oral mucositis in patients receiving chemotherapy, and to estimate its effect in decreasing pro-inflammatory cytokine production after chemotherapy. Materials and Methods This study utilized a placebo-controlled, randomized, double-blind, and cross-over design. Twenty-five patients undergoing intensive chemotherapy were randomly assigned to receive a mouth wash containing OLE, benzydamine hydrochloride, or placebo in 3 different cycles of chemotherapy. Oral mucositis severity was assessed using the World Health Organization criteria and Oral Mycositis Assessment Scale. Patients were evaluated weekly until 15 days after chemotherapy for each cycle. Salivary levels of interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) were evaluated by enzyme-linked immunosorbant assay. Results Oral mucositis rates and severity after 2 weeks were significantly lower in the OLE and benzydamine groups compared to the placebo group. The IL-1β and TNF-α levels were significantly decreased in the OLE group compared to the other groups. Conclusion Preliminary findings indicate that OLE is effective in reducing IL-1β and TNF-α levels after chemotherapy and demonstrates a therapeutic effect against oral mucositis.

      Background Various methods, including clinical and radiographic techniques, can be used to assess periodontal regeneration in interproximal areas. The goal of the present study was to compare the papilla length relative to the alveolar bone crest measured by clinical, intrasurgical, and radiographic techniques. Materials and methods The study sample included 250 interproximal papillae in 68 patients with generalized chronic periodontitis. The papilla length from the alveolar bone crest was measured clinically (as the actual papilla length, APL), intrasurgically (as the bone probing length, BPL), and radiographically (as the radiographic bone length, RBL). Measurements were standardized by using acrylic resin stents, XCP rinn, a paralleling technique, and/or a radiographic grid. Results The mean (± standard deviation) for RBL was 4.9 ± 0.8 mm, BPL was 5.1 ± 0.6 mm, and APL was 5.1 ± 0.6 mm. Correlations between RBL and APL and between BPL and APL were 0.918 and 0.943, respectively (both P < 0.01). Conclusion If the clinical recordings are appropriately standardized, then noninvasive radiographic methods can be used to evaluate the papilla length with good accuracy.

      Dentinogenesis imperfecta (DI) associated with osteogenesis imperfecta (OI) is a genetic disorder that affects the connective tissues and results in dentine dysplasia. This case report discusses the systemic and dental manifestations of OI and DI in a 4-year-old child, with moderate presentation of both disorders, who was treated at King Fahad Military Medical Complex in Dhahran. Dental treatment included the use of strip and stainless-steel crowns under local anesthesia, as well as behavior modification techniques. Rigorous home care instructions, including reinforcement of the oral hygiene practice and avoidance of any episode that may lead to bone fracture, were discussed with the parents. The case was reevaluated at 3-month follow-up visits, wherein the medical and dental histories were updated, the child’s growth was monitored, periodic clinical and radiographic examinations were performed, and the oral hygiene was evaluated via the debris index score and caries risk assessment. Further treatment of the permanent dentition may be needed in the future.

      Author(s): Alaa’a M. Salloum
      Problem statement Despite advances in materials and techniques, complete dentures made of acrylic resin experience an increase in the occlusal vertical dimension (OVD) during processing. Many factors that affect the OVD of complete dentures are known. However, no study has examined the effect of using high-expansion dental stone (type V) as an investing material on the OVD. Purpose This study investigated the effects of using a high-expansion dental stone as an investing material on changes in the OVD of complete dentures. Material and Methods Twenty sets of simulated upper and lower dentures were processed by the compression molding technique. Specimens were equally divided into 2 groups. In the dental stone type III (DST III) group, the lower, middle, and upper parts of a flask were filled with DST III. In the dental stone type V (DST V) group, the procedure was the same as in the DST III group, except that the middle layer was made of high-expansion DST V. Changes in the OVD were measured before and after denture processing. Collected data were analyzed with t-test statistics. Differences were considered statistically significant at the 95% confidence level. Results Both groups showed a small increase in the OVD as a result of processing, but the OVD increase was significantly less in the DST V group compared to the DST III group. Conclusion . High-expansion DST V can be recommended as an investing material to reduce the increase in the OVD that may occur while processing complete dentures.

      Aim The aim of this study was to measure the amount of nickel (Ni) and chromium (Cr) released into the saliva of Saudi patients treated with fixed orthodontic appliances. Materials and Methods Ninety salivary samples were collected in a cross-sectional manner after different periods of orthodontic treatment. Forty samples were collected from patients (17 males, 23 females) with fixed orthodontic appliances, which primarily consisted of 4 bands, 20 stainless steel brackets, and upper and lower nickel titanium or stainless-steel arch wires. The other 50 samples were collected from people without appliances (24 males, 26 females). Samples were analyzed using Inductive Coupled Plasma / Mass Spectrometry and Inductively Coupled Plasma Optical Emission Spectroscopy to measure Ni and Cr levels, respectively. Student’s t-test was used to compare Ni and Cr levels in the treated and untreated control groups Results Ni levels ranged 0–12.1 μg/L in the experimental group and 0–8.2 μg/L in the control group (p < 0.05). Cr levels ranged 0.8–5.4 μg/L and 0.6–6.7 μg/L, respectively (p > 0.05). Conclusion Fixed orthodontic appliances resulted in a non-toxic increase in salivary levels of Ni, but no change in Cr levels. Duration of orthodontic treatment did not affect Ni and Cr levels in the saliva.

      Objective To compare the attitudes of preclinical and clinical dental students toward their own oral health using the Hiroshima University–Dental Behavioral Inventory (HU-DBI). Methods The English-language version of the 20-item HU-DBI was distributed to all preclinical and clinical students at the College of Dentistry, University of Dammam, Kingdom of Saudi Arabia. Dichotomized (agree/disagree) responses to 12 HU-DBI items were used in this study, with a maximum possible score of 12. Responses to the remaining eight statements reflected general oral health attitudes and were excluded from the analysis. Data were analyzed statistically. Results The overall response rate was 72.2% (preclinical, 72.5%; clinical, 72%). The mean HU-DBI score was significantly higher among clinical than among preclinical dental students (7 vs. 5.8; P < 0.05). Higher proportions of preclinical than clinical students worried about visiting the dentist and postponed dental visits until they experienced toothache. Furthermore, more preclinical than clinical students reported that their gums bled upon brushing, that they used a child-sized toothbrush, that they had observed white, sticky deposits on their teeth, and that they used strong strokes for toothbrushing. More clinical than preclinical students reported that they did not feel that the condition of their teeth was worsening despite brushing, that they worried about the color of their teeth, that they brushed each of their teeth carefully, and that they checked their teeth in the mirror after brushing. Conclusions Dental health awareness programs should be implemented and information about positive oral health attitudes should be provided to the students at an initial stage of dental training.

      Introduction Dentists prescribe antibiotics for both therapeutic and prophylactic reasons to manage oral and dental infections. Antibiotic prescriptions can be associated with unfavorable side effects and the development of resistance. Aim of the Study A survey was conducted among dental specialists (DSs) and general dental practitioners (GDPs) at private dental clinics in Riyadh, Saudi Arabia to assess their level of knowledge regarding the action of antibiotics, their use and misuse in oral conditions, systemic diseases and prophylaxis,. Subjects and Method A total of 380 identical surveys that contained 32 questions were completed by DSs and GDPs in a supervised setting. Descriptive statistics were calculated to assess the overall knowledge of both DSs and GDPs, and their knowledge within each category of questions. Independent t-tests were used to ascertain whether there were significant differences between DSs and GDPs. A scatterplot diagram was used to test for a correlation between the years of experience of practitioners and their knowledge level. Result The response rate was 79.7%. An acceptable level of knowledge was attained by 85.5% of dentists and 42.2% just passed. The percentage of dentists with an acceptable level of knowledge regarding prophylaxis was 51%. The scores for overall information levels about antibiotics among both DSs and GDPs were close to 70%. The percentage of DSs with an acceptable level of knowledge on antibiotic actions was 69.2%, 90.7% for oral conditions and 66.7% for medical conditions, compared to 66.8%, 88.7% and 64.8%, respectively, for GDPs. No significant relationship was found between the experience and knowledge level. Conclusions Our findings suggest that the overall knowledge level of dentists about antibiotics is acceptable, but more focus should be given to their ongoing training regarding the pharmacological aspects, pertinent medical conditions and prophylactic use of antibiotics.

      Objectives The purpose of this study was to determine the number, types, and locations of oral mucosal lesions among 530 patients who attended the Admission Clinic at the Kuwait University Dental Center to determine prevalence and risk factors for oral lesions. Subjects and methods Intraoral soft tissue examination was performed on new patients seen between January 2009 and February 2011. The lesions were divided into six major groups: white, red, pigmented, ulcerative, exophytic, and miscellaneous. Results Five hundred thirty patients were screened, out of which 308 (58.1%) had one or more lesions. A total of 570 oral lesions and conditions were identified in this study, of which 272 (47.7%) were white, 25 (4.4%) were red, 114 (20.0%) were pigmented, 21 (3.7%) were ulcerative, 108 (18.9%) were exophytic, and 30 (5.3%) were in the miscellaneous group. Overall, Fordyce granules (n = 116; 20.4%) was the most frequently detected condition. A significantly higher (p < 0.001) percentage of older patients (21 – 40 y and ⩾ 41 y) had oral mucosal lesions than those in the ⩽ 20 y age group. A significantly higher (p < 0.01) percentage of smokers had oral mucosal lesions than did nonsmokers. Most of the lesions and conditions were found on the buccal mucosa and gingiva. Conclusions White, pigmented, and exophytic lesions were the most common types of oral mucosal lesions found in this study. Although most of these lesions are innocuous, the dentist should be able to recognize and differentiate them from the worrisome lesions, and decide on the appropriate treatment.

      Objectives To evaluate the sources of stress among students in the dental school environment, their perceived levels of stress and effective coping strategies. Methods The study was conducted during the first semester of the academic year, 2009–10, at the College of Dentistry, King Saud University, Saudi Arabia. The eligible study group consisted of 556 undergraduate dental students from all five class years; they were surveyed with a detailed assessment tool. The validated and translated questionnaire comprised the modified version of the dental environmental stress (DES) survey, the perceived stress scale (PSS) and the brief coping scale (BC). Results The overall findings substantiated with multiple regression indicate that, out of 20 factors of both DES and BC instruments, 6 factors were significantly and independently related to perceived stress scores (F = 34.638; p < 0.0001). Especially, the factors self-efficacy and workload of DES and the factors behavioral disengagement, denial, positive reframing and venting of BC were positively and independently related to perceived stress scores. Conclusions Dental students displayed relatively high perceived stress scores. Female, advanced and married, compared with male, junior and single students reported more stress. Changes in certain environmental factors and coping strategies independently affected the perceived stress score. Strategies for stress management must be incorporated into dental education to ensure the output of effective dentists.

      Objective The purpose of this study was to examine the causality and severity of maxillofacial trauma (MFT) among patients referred to a tertiary heath care center in the southern region of Saudi Arabia. Materials and Methods The charts of all MFT patients referred to the tertiary care center from September 2010 to November 2011 were retrospectively reviewed. Pertinent data, including patient age, gender, and cause of injury, were obtained from 101 selected charts. Results Male patients comprised 91% of the 101 selected cases. The highest percentage of MFT cases (88.7%) were caused by road traffic accidents (RTAs). Physical altercations and sports injuries accounted for approximately 6% and 2.8% of MFT cases, respectively. A high fracture: patient ratio of 2.4: 1 was observed, which was likely due to vehicular speeding involved in RTAs in the mountain regions. Conclusion RTAs are a major cause of MFT in the southern region of Saudi. These accidents cause a heavy burden on the health care sector.

  • Aesthetic replacement of an anterior tooth using the natural tooth as a
           pontic; an innovative technique

    • Abstract: Publication date: Available online 10 April 2013
      Source:The Saudi Dental Journal

      This article presents a novel technique for replacing an anterior tooth. A new modification to the clinical technique of direct fabrication of a resin-bonded bridge was employed, in which the patient’s natural tooth was used as a pontic. Treatment with this modification led to overall improved aesthetics and reduced treatment cost. The natural tooth pontic was stabilized in the extraction socket with a resin-wire splint as a provisional restoration to maintain the gingival architecture while the permanent bridge was being constructed.

      Aim To study the effect of nonsurgical periodontal therapy on the expression frequencies of human beta-defensin (HBD)-1, -2, and -3 in the gingival crevicular fluid (GCF) of patients affected by localized aggressive periodontitis Materials and methods Twenty patients affected by localized aggressive periodontitis (age range, 20–35 years) and 20 healthy subjects (age range, 21–37 years) were examined with clinical periodontal parameters and radiographic examination with the long-cone parallel technique. All periodontitis patients underwent nonsurgical periodontal therapy combined with doxycycline treatment and a maintenance program (including brushing with regular toothpaste). GCF samples were collected from patients and healthy control subjects at baseline as well as 3 months after periodontal therapy for the patient group. Results In the patient group, the expression frequencies of HBD-1, -2, and -3 mRNA at baseline were 30%, 85%, and 35%, respectively, which changed after periodontal therapy to 80%, 45%, and 85%, respectively (all P < 0.001). In the healthy control subjects, the expression frequencies were 95%, 40%, and 95% for HBD-1, -2, and -3, respectively, which were different from those of diseased patients at baseline (all P < 0.001). Conclusions The appropriate expression of HBD peptides in health and disease may contribute to the maintenance of periodontal homeostasis, possibly through its antimicrobial effects and the promotion of adaptive immune responses.

      Objective The purpose of the study was to investigate and evaluate the professional attitudes and behaviors acquired by students and recently graduated dentists during undergraduate education at King Saud University. Methods This cross-sectional survey used a 27-item questionnaire covering four cumulative theoretical dimensions of professionalism. Questionnaires were distributed to fifth-year students, interns, and demonstrators in the College of Dentistry during the academic year 2010–2011, and 203 completed questionnaires were used in analyses. Descriptive statistics were used to summarize responses. Crosstab and chi-squared tests were used, with statistical significance set at P < 0.05. Results The response rate was 79.3% (43.6% of males, 94% of females). Eighty-seven questionnaires were collected from fifth-year students, 92 from interns, and 24 from demonstrators. Many (59%) participants demonstrated high levels of professional attitudes and behaviors, whereas 40% did not comply with the elements of professionalism. Analyses revealed highly significant differences in certain responses with regard to gender, academic level, and grade point average. Conclusions Although some participants did not possess all professional qualities, all participants possessed at least some elements of professionalism measured in this study. We thus recommend a strategic effort to develop targeted plans emphasizing professionalism at all levels of the dental school curriculum. High-profile role modeling, lectures, seminars, and academic ceremonies are ways of achieving professional development among dental students in parallel with their acquisition of basic scientific knowledge and clinical skills. This approach will formally and informally communicate that professionalism is a core value.

  • The Effectiveness of Four Methods for Stain Removal from Direct
           Resin-Based Composite Restorative Materials

    • Abstract: Available online 17 March 2013
      Publication year: 2013
      Source:The Saudi Dental Journal

      Background/purpose Few studies investigated the best method for removing stains from different types of resin-based composites restorations and compared them to the more recently introduced nanocomposites. This study compared the effect of four methods for stain removal from composite resins; finishing with Sof-lex discs, using pumice and brush, bleaching with 10% carbamide peroxide and 38% hydrogen peroxide. Materials and Methods Twenty disc specimens were prepared. Specimens were immersed in a staining solution for three weeks. The stained surfaces of five specimens from each RBC material were treated with one of the treatment procedures. Colorimetric measurements were taken using spectrophotometer prior to and after staining, and then repeated after surface treatments. Color difference values were calculated. Results One-way ANOVA indicated significant differences in color change of the three composite resin materials following staining. Filtek Z250 showed the least susceptibility to discoloration followed by Renamel, Filtek Supreme was the material most prone to discoloration. Two-way ANOVA and Tukey”s Post Hoc showed that all stain removing procedures except polishing with pumice, were able to return Filtek Z250 to clinically acceptable color difference. While bleaching with 38% carbamide peroxide was not effective with Renamel. Only pumice and 10% carbamide peroxide were able to return Renamel to clinically acceptable color difference. Conclusion Compositions of resin-based composite resins play an important role in its susceptibility to stain and its amenability to stain removal procedures. Home bleaching showed good results for the three materials, while office bleach was the least effective.

  • Minimally invasive reconstruction of periodontally involved teeth by
           aesthetics coloured composite resin: case report

    • Abstract: Available online 14 March 2013
      Publication year: 2013
      Source:The Saudi Dental Journal

      Gingival recession causes not only aesthetic problems, but problems with oral hygiene, plaque accumulation, speech, and tooth sensitivity. Replacing the missing gingival tissue with composite resin, when indicated, can be a time- and cost-effective solution. Here we report the case of a 25-year-old female who presented with generalized gingival recession. Black triangles were present between the maxillary and mandibular anterior teeth due to loss of interdental tissues, caused by recent periodontal surgery. She also had slightly malposed maxillary anterior teeth. The patient elected to replace gingival tissue with pink composite resin and to alter the midline with composite resin veneers. The first treatment phase involved placement of pink gingival composite to restore the appearance of interdental papilla to her upper (16, 15, 14, 13, 12, 11, 21, 22, 23, and 24) and lower (34, 33, 32, 31, 41, 42, 43, and 44) teeth. Phase two was to place direct composite resin bonded veneers on her upper (16, 15, 14, 13, 12, 11, 21, 22, 23, and 24) teeth to alter midline and achieve desired color. The third treatment phase was to level the lower incisal edge shape by enameloplasty (31, 32, 41, and 42) to produce a more youthful and attractive smile. This case report and a brief review attempt to describe the clinical obstacles and the current treatment options along with a suggested protocol. Use of contemporary materials such as gingival colored composite to restore lost gingival tissue and improve aesthetics can be a simple and cost-effective way to manage patients affected by generalized aggressive periodontitis (AgP).

      Aim To evaluate and compare the perceptions of Saudi dentists and lay people to altered smile features. Methods Thirty-six digital smile photographs with altered features were used. Altered features included the following: crown length, width, gingival level of the lateral incisors, gingival display, midline diastema, and upper midline shift. The photographs were presented to a sample of 30 dentists and 30 lay people with equal gender distribution. Each participant rated each picture with a visual analogue scale, which ranged from 0 (very unattractive) to 100 (very attractive). Results Dentists were more critical than lay people when evaluating symmetrical crown length discrepancies. Compared to lay people, Saudi dentists gave lower ratings to a crown length discrepancy of >2mm (P

  • A systematic review of population-based dental caries studies among
           children in Saudi Arabia

    • Abstract: January 2013

      Objective Dental caries critically impacts the health and development of children. Understanding caries experience is an important task for Saudi Arabian policymakers to identify intervention targets and improve oral health. The purpose of this review is to analyze current data to assess the nationwide prevalence and severity of caries in children, to identify gaps in baseline information, and to determine areas for future research. Methods A search of published and unpublished studies in PubMed, Google, and local Saudi medical and dental journals was conducted for the three keywords “dental,” “caries,” and “Saudi Arabia.” The inclusion criteria required that the articles were population-based studies that assessed the prevalence of dental caries in healthy children attending regular schools using a cross-sectional study design of a random sample. Results/discussion The review was comprised of one unpublished thesis and 27 published surveys of childhood caries in Saudi Arabia. The earliest study was published in 1988 and the most recent was published in 2010. There is a lack of representative data on the prevalence of dental caries among the whole Saudi Arabian population. The national prevalence of dental caries and its severity in children in Saudi Arabia was estimated to be approximately 80% for the primary dentition with a mean dmft of 5.0 and approximately 70% for children’s permanent dentition with a mean DMFT score of 3.5. The current estimates indicate that the World Health Organization (WHO) 2000 goals are still unmet for Saudi Arabian children. Conclusion Childhood dental caries is a serious dental public health problem that warrants the immediate attention of the government and the dental profession officials in Saudi Arabia. Baseline data on oral health and a good understanding of dental caries determinants are necessary for setting appropriate oral health goals. Without the ability to describe the current situation, it is not possible to identify whether progress is being made toward these goals. A roadmap with a clear starting point, destination, and pathway is a desperately needed tool to improve the oral health of Saudi Arabian children.

  • Oral manifestations of lipoid proteinosis: A case report and literature
           review

    • Abstract: Available online 20 February 2013
      Publication year: 2013
      Source:The Saudi Dental Journal

      Lipoid proteinosis is an uncommon autosomal recessive metabolic disorder that presents in early life with hoarseness and pox-like aceniform scars involving the skin and mucous membranes. Previous studies have attributed the prevalence of lipoid proteinosis to consanguinous parents. This paper reports a classical case of lipoid proteinosis with oral manifestations but without a history of consanguinity.

  • Stud attachments for the mandibular implant-retained overdentures:
           Prosthetic complications. A literature review

    • Abstract: Available online 6 February 2013
      Publication year: 2013
      Source:The Saudi Dental Journal

      A plethora of attachment systems for mandibular two-implant overdentures is currently available often without evidence-based support. Technical aspects are now parameters considered when choosing the appropriate attachment. Despite the increasing use of the Locator attachments, studies regarding their properties remain scarce. Peer reviewed articles published in English up to 2011, were identified through a MEDLINE search (Pubmed and Elsevier) and a hand search of relevant textbooks and annual publications. Emphasis was made on the technical complications as well as the loss of retention related to the attachments in implant-retained overdentures, primarily the Locator attachment. The evaluation of the long-term outcome of implant overdentures and complications associated with different attachment systems may provide useful guidelines for the clinician in selecting the type of attachment system and overdenture design.

  • Nanorobots: Future in dentistry

    • Abstract: Available online 17 January 2013
      Publication year: 2013
      Source:The Saudi Dental Journal

      The purpose of this paper is to review the phenomenon of nanotechnology as it might apply to dentistry as a new field called nanodentistry. Treatment possibilities might include the application of nanotechnology to local anesthesia, dentition renaturalization, the permanent cure for hypersensitivity, complete orthodontic realignment in a single visit, covalently bonded diamondized enamel, and continuous oral health maintenance using mechanical dentifrobots. Dental nanorobots could be constructed to destroy caries-causing bacteria or to repair tooth blemishes where decay has set in, by using a computer to direct these tiny workers in their tasks. Dental nanorobots might be programed to use specific motility mechanisms to crawl or swim through human tissue with navigational precision, to acquire energy, to sense and manipulate their surroundings, to achieve safe cytopenetration, and to use any of a multitude of techniques to monitor, interrupt, or alter nerve-impulse traffic in individual nerve cells in real time.
