      Author(s): Ahmad Alshadwi , Mohammed Nadershah , Timothy Osborn
      Objective The aim of this article is to review the mechanism of action, physiological effects, and therapeutic applications of botulinum neurotoxins in the head and neck area. Study design An extensive literature search was performed using keywords. The resulting articles were analyzed for relevance in four areas: overview on botulinum neurotoxins, the role of botulinum neurotoxins in the management of salivary secretory disorders, the role of botulinum neurotoxins in the management of facial pain, and the role of botulinum neurotoxins in head and neck movement disorders. Institutional review board approval was not needed due the nature of the study. Results Botulinum neurotoxin therapy was demonstrated to be a valuable alternative to conventional medical therapy for many conditions affecting the head and neck area in terms of morbidly, mortality, and patient satisfaction with treatment outcomes. Conclusion Botulinum neurotoxin therapy provides viable alternatives to traditional treatment modalities for some conditions affecting the head and neck region that have neurological components. This therapy can overcome some of the morbidities associated with conventional therapy. More research is needed to determine the ideal doses of botulinum neurotoxin to treat different diseases affecting the head and neck regions.

      Aim The purpose of the present study was to correlate the degree of temporomandibular disorder (TMD) severity and skin temperatures over the temporomandibular joint (TMJ) and masseter and anterior temporalis muscles. Materials and methods This blind cross-sectional study involved 60 women aged 18–40 years. The volunteers were allocated to groups based on Fonseca anamnestic index (FAI) score: no TMD, mild TMD, moderate TMD, and severe TMD (n = 15 each). All volunteers underwent infrared thermography for the determination of skin temperatures over the TMJ and masticatory muscles. Results Weak, positive, significant associations were found between FAI score and skin temperatures over the left TMJ (rs = 0.195, p = 0.009) and right TMJ (rs = 0.238, p = 0.001). Temperatures over the right and left TMJ were significantly higher in groups with more severe TMD (p < 0.05). Conclusion FAI score was associated with skin temperature over the TMJ, as determined by infrared thermography, in this sample. Women with more severe TMD demonstrated a bilateral increase in skin temperature.

      Objective This study aims to assess the orthodontic diagnostic skills, referral patterns, and the perceptions of orthodontic benefits of pediatric and general dentists in comparison with orthodontists. Materials and Methods Two online surveys were e-mailed to pediatric dentists, general dentistry practitioners, and orthodontists registered as members of the Saudi Dental Society and the Saudi Orthodontic Society. The surveys included questions about the type of orthodontic treatment provided, referral trends, and timing; presumed benefits associated with successful orthodontic treatment; and diagnosis and treatment plans of seven cases representing different malocclusions. Results In total, 25 orthodontists, 18 pediatric dentists, and 14 general practitioners completed the survey. Only 38.8% of pediatric dentists and 7.1% of general practitioners reported that they practiced orthodontics clinically. The perceptions of the three groups towards the benefits of orthodontic treatment were comparable in the psychosocial areas. However, the orthodontists perceived significantly lesser effects of orthodontic treatment on the amelioration of temporomandibular disorder (TMD) symptoms. Pediatric dentists tended to rate the need and urgency of treatment higher, while general practitioners tended to rate the need of treatment lower. The selected treatment plans for three early malocclusion cases showed the greatest discrepancies between the orthodontists and the other two groups. Conclusions The orthodontists consistently and significantly downplayed the perceived benefit of orthodontic treatment to reduce TMD symptoms. Also, while there was a similarity in the diagnosis, there were notable differences in the proposed treatment approaches, perceived treatment need, and timing of intervention between the three groups of practitioners.

      Author(s): Haidar Al-Alawi , Abdulfatah Al-Jawad , Mahdi Al-Shayeb , Ali Al-Ali , Khalifa Al-Khalifa
      Objective This case-control study was performed to determine the prevalence of dental caries and periodontal conditionsina population of patients with sickle cell disease (SCD) in the Eastern Province of Saudi Arabia. Materials and Methods The decayed, missing and filled teeth (DMFT) index, community periodontal index (CPI), and plaque index were recorded for 33 patients with SCD and 33 age- and sex-matched controlsubjects(age range, 18–38 years) in Al-Qatif Central Hospital, Qatif, Saudi Arabia. Data on participants’ socioeconomic status and oral health behaviors were recorded. Disease severity wasclassified for all patients with SCD. Results Decayed teeth weresignificantly more prevalentin individuals with SCD than in control subjects(p=0.036) due to oral hygiene negligence. The mean number of filled teeth was significantly lower in individuals with SCD than in control subjects(p=0.015) due to the lack of appropriate and timely treatment. No difference inDMFT index, CPI, or plaque index was observed between groups. Conclusion The data suggest that patients with SCD have increased susceptibility to dental caries, with a higher prevalence of tooth decay and lower prevalence of filled teeth. Known caries risk factors influenced oral health more markedly than did factors related to SCD.

      Author(s): Munad J. Al-Duliamy , Nidhal H. Ghaib , Omar A. Kader , Bashar H. Abdullah
      Objectives To examine the clinical and histological effects of locally injected strontium on the anchoring unit of a rat model of an experimental relapsed tooth movement. Materials and methods Thirty-six 10-week-old male Wister rats were randomly divided into two groups of 18 animals that were then randomly divided into three subgroups of six animals corresponding to three observation periods: T1=1week, T2=2weeks, and T3=3weeks. In the first experiment, both the right and left maxillary first molars were moved buccally with a standardized expansive spring. Strontium chloride solution was injected every 2days into the subperiosteal area buccal to the left maxillary first molar (the experimental side). The right-sided first molar was injected with distilled water as a control. In the second experiment, maxillary first molars were moved buccally with the spring. After 3weeks, the spring was removed. Two days before the spring removal, strontium chloride was injected into the palatal side of left-sided maxillary first molar and distilled water was injected into the palatal side of the right-sided maxillary first molar as in experiment 1. Results At the end of the experimental period, significant levels of inhibition were noted in terms of both tooth movement and relapse movement in strontium-injected sides. Histological examinations showed that strontium enhanced the number of osteoblasts and reduced the number of osteoclasts. Conclusion The local injection of strontium can inhibit the degree of experimental and relapsed tooth movement in a rat model.

      Author(s): Nabil Muhsen Al-Zubair
      Objective Information about maxillary arch and palatal dimensions in human populations is important for clinical orthodontics. This study was conducted to assess the determinants of maxillary arch dimensions in a sample of Yemeni individuals aged 18–25 years. Materials and Methods The study sample comprised 214/765 adults (101 women, 113 men) who underwent clinical examination and fulfilled the study criteria. Study models were constructed and evaluated to measure maxillary arch and palatal dimensions. Results The majority of mean maxillary arch dimensions were significantly greater in men than in women, with inter–second molar distance showing the greatest difference and palatal depth showing the least difference. Conclusion Measurements of palatal depth and relationships of the canines to one another and to other teeth thus had the widest ranges, implying that these dimensions are the strongest determinants of maxillary arch size.

  • CBCT imaging – A boon to orthodontics

    • Abstract: Publication date: Available online 22 October 2014
      Source:The Saudi Dental Journal
      Author(s): Genevive L. Machado
      The application of innovative technologies in dentistry and orthodontics has been very interesting to observe. The development of cone-beam computed tomography (CBCT) as a preferred imaging procedure for comprehensive orthodontic treatment is of particular interest. The information obtained from CBCT imaging provides several substantial advantages. For example, CBCT imaging provides accurate measurements, improves localization of impacted teeth, provides visualization of airway abnormalities, it identifies and quantifies asymmetry, it can be used to assess periodontal structures, to identify endodontic problems, to plan placement sites for temporary skeletal anchorage devices, and to view condylar positions and temporomandibular joint (TMJ) bony structures according to the practitioner’s knowledge at the time of orthodontic diagnosis. Moreover, CBCT imaging involves only a minimal increase in radiation dose relative to combined diagnostic modern digital panoramic and cephalometric imaging. The aim of this article is to provide a comprehensive overview of CBCT imaging, including its technique, advantages, and applications in orthodontics.

  • Subjective image quality comparison between two digital dental
           radiographic systems and conventional dental film

    • Abstract: Publication date: Available online 19 August 2014
      Source:The Saudi Dental Journal
      Author(s): Muhammed Ajmal , Mohamed I. Elshinawy
      Objectives Digital radiography has become an integral part of dentistry. Digital radiography does not require film or dark rooms, reduces X-ray doses, and instantly generates images. The aim of our study was to compare the subjective image quality of two digital dental radiographic systems with conventional dental film. Materials & methods A direct digital (DD) ‘Dexis’ system by Sirona, a semi-direct (SD) digital system by Vista-scan, and Kodak ‘E’ speed dental X-ray films were selected for the study. Endodontically-treated extracted teeth (n =25) were used in the study. Details of enamel, dentin, dentino-enamel junction, root canal filling (gutta percha), and simulated apical pathology were investigated with the three radiographic systems. The data were subjected to statistical analyzes to reveal differences in subjective image quality. Results Conventional dental X-ray film was superior to the digital systems. For digital systems, DD imaging was superior to SD imaging. Conclusion Conventional film yielded superior image quality that was statistically significant in almost all aspects of comparison. Conventional film was followed in image quality by DD, and SD provided the lowest quality images. Conventional film is still considered the gold standard to diagnose diseases affecting the jawbone. Recommendations Improved software and hardware for digital imaging systems are now available and these improvements may now yield images that are comparable in quality to conventional film. However, we recommend that studies still use more observers and other statistical methods to produce ideal results.

      Background and purpose Polymerization of bonding agents (BA) is a critical factor in determining the success of bonded restorations. We aimed to assess the effects of two light curing units and two temperatures on the extent of polymerization (EP) of a commercial BA and an experimental BA. Methods Forty BA specimens were randomly divided into 8 subgroups of n =5 to compare the polymerization of two BAs (experimental/Scotchbond) based on the variables: temperature (23/37°C) and light-curing unit (quartz-tungsten-halogen/light-emitting diode). The EP (%) was measured using differential scanning calorimetry, and analyzed using the t-test, two- and three-way analyses of variance (ANOVA), and the Bonferroni test (α =0.05). Results There were significant differences between the EP results between the two BAs (P =0.012) and due to the different temperatures (P =0.001), but not between the different light-curing units (P =0.548). The interaction between BA and temperature was significant (P <0.001). The other interactions were nonsignificant. Conclusions The two light-curing units had similar effects on the EP. The EP values were better when curing was performed at human body temperature.

      Aim To characterize microstructure, hardness and thermal properties of experimental Ag-based soldering alloys for dental applications. Materials and methods Ag12Ga (AgGa) and Ag10Ga5Sn (AgGaSn) were fabricated by induction melting. Six samples were prepared for each alloy and microstructure, hardness and their melting range were determined by, scanning electron microscopy, energy dispersive X-ray (EDX) microanalysis, X-ray diffraction (XRD), Vickers hardness testing and differential scanning calorimetry (DSC). Results Both alloys demonstrated a gross dendritic microstructure while according to XRD results both materials consisted predominately of a Ag-rich face centered cubic phase The hardness of AgGa (61±2) was statistically lower than that of AgGaSn (84±2) while the alloys tested showed similar melting range of 627–762°C for AgGa and 631–756°C for AgGaSn. Conclusion The experimental alloys tested demonstrated similar microstructures and melting ranges. Ga and Sn might be used as alternative to Cu and Zn to modify the selected properties of Ag based soldering alloys.

      Background Matrix metalloproteinase-1 (MMP-1) is a member of a family of enzymes that can degrade most extracellular matrix macromolecules. Extracellularly, MMPs are controlled by tissue inhibitors of metalloproteinases (TIMPs) and by mechanisms of pro-MMP activation. Levels of MMPs and TIMPs change during healing, inflammation, and normal tissue turnover. Herein we aimed to evaluate the levels of MMP-1 and TIMP-1 in gingival crevicular fluid (GCF) from periodontally healthy patients (control group) and chronic periodontitis patients before and after phase 1 therapy. Methods In this study we examined 30 patients who had chronic periodontitis with probing depth sites ⩾5mm and a clinical attachment level (CAL) ⩾5mm. We included 30 periodontally healthy patients as a control. Clinical measurements such as plaque (PI) and gingival (GI) indices, papillary bleeding index (PBI), probing depths (PD), and CAL were recorded both before treatment (BT) and after phase I periodontal treatment (AT). Assays for MMP-1 and TIMP-1 were performed with an enzyme-linked immunosorbent assay (ELISA) method. Results All clinical parameters were significantly reduced at the post-therapy visit. MMP-1 levels were significantly higher in patients BT than the controls; however, the patients AT were not statistically different than the controls. TIMP-1 levels in patients BT were significantly lower than in the controls and significantly lower than patients AT. We observed a significant positive correlation between GCF volume and MMP-1 levels. Furthermore, TIMP-1 levels were significantly negatively correlated with both GCF volume and all clinical parameters. Conclusions We observed that as the extent of periodontal destruction increases, MMP-1 concentration increases and TIMP-1 concentration decreases in GCF. When chronic periodontitis patients were treated by scaling and root planing (SRP), the average MMP-1 concentrations decreased and TIMP-1 concentrations increased in GCF.

      Author(s): Nazish Fatima
      Purpose The aim of present study was to evaluate extended curing times on the degree of conversion (DC) of filled and unfilled resin-based materials used as pit and fissure sealants. Materials and methods The materials examined were a flowable composite (Filtek™ Z350 XT Flowable) and a pit and fissure sealant (Clinpro™ Sealant). Thirty disks of each material were prepared. The 30 disks made of the flowable composite were divided into three groups (n =10 each) according to the three different curing times studied: 20s (group 1), 40s (group 2), and 60s (group 3). Similarly, the 30 disks made of the pit and fissure sealant were divided into three groups (n =10 each) according to the three different curing times: 20s (group 4), 40s (group 5), and 60s (group 6). After polymerization, the disks were removed from the mold and stored in dry, lightproof containers in an incubator at 37°C for 24h. The DC was obtained using an Avatar 320 FTIR spectrometer. Then the data were analyzed using the Kruskal–Wallis test and the Fisher’s least significant difference post hoc test for multiple comparisons (alpha=0.05). Results DC values for the flowable composite (Filtek™ Z350 XT) were higher (p =0.002) than those for the pit and fissure sealant (Clinpro™ Sealant). Group 2 and group 5 showed significantly higher DC values than group 1 and group 4, respectively. There was no difference between groups 2 and 3 or between groups 5 and 6 (p =2.93). Conclusion An extended curing time improves the DC to some extent for both materials.

      Introduction Every person has certain features that make them radically distinct from others. One such feature is lip prints. Lip prints remain the same throughout life and are uninfluenced by injuries, diseases, or environmental changes. Different individuals have specific blood groups according to the various antigen–antibody reactions in their bloodstream. Aim To determine the distribution of different patterns of lip prints among subjects having different ABO and Rh blood groups. Objective To determine the correlation between respective characteristics of subjects. Methodology In this study, lip prints were obtained from 122 subjects (62 males and 60 females), and associated blood-group matching was performed to determine the predominant lip print type and to determine any correlation between lip print types and blood groups. Tsuchihashi’s classification of type I (complete vertical grooves), type I′ (incomplete vertical grooves), type II (forking grooves), type III (intersecting grooves), type IV (reticular grooves), and type V (indeterminate grooves) was used to compare with the ABO and Rh blood grouping systems. Result No correlation was found between lip prints and blood groups. Conclusion No significant correlation exists between blood group and lip prints. Lip prints play a vital role in identification because they are unique.

      Accidental displacement of an impacted third molar, either a root fragment, crown, or the entire tooth, is a rare complication that occurs during exodontia. The most common sites of dislodgment of an impacted mandibular third molar fragment are the sublingual, submandibular, and pterygomandibular spaces. Removal of a displaced root tip from these spaces may be complex due to poor visualization and limited access. A thorough evaluation of all significant risk factors must be performed in advance to prevent complications. This paper reports the case of a patient who presented with a mandibular third molar root that was displaced into submandibular space. The case was managed intraorally under local anaesthesia and review of the literature.

      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.

      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

      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.

      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.

      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.

      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.

      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): 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.

  • Detection, removal and prevention of calculus: Literature Review

    • Abstract: Publication date: Available online 18 December 2013
      Source:The Saudi Dental Journal
      Author(s): Deepa G Kamath , Sangeeta Umesh Nayak
      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.

      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

      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.

  • In-Vitro Accuracy and Reproducibility Evaluation of Probing Depth
           Measurements of Selected Periodontal Probes

    • Abstract: Publication date: Available online 27 November 2013

      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.

      Author(s): Khadija Muhamed Ahmed
      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.

  • Influence of high expansion dental stone used as investing medium on the
           changes in occlusal vertical dimension of complete dentures

    • Abstract: Publication date: Available online 28 October 2013
      Source:The Saudi Dental Journal
      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.
