  • Salivary Levels of Hemoglobin for Screening Periodontal Disease: A
           Systematic Review

    • Abstract: Periodontal disease is a common inflammatory disease. It affects about 20–50% of global population in both developed and developing countries. Early detection of slight changes of periodontal tissue plays an important role in prevention of onset and progression of periodontal disease. Hence, there is a need of a screening test to assess periodontal tissue for health check-ups. Salivary levels hemoglobin (Hb) has been proposed to assess the conditions of the inflammation of gingiva. The aim of this systematic review was to evaluate and summarize critically the current evidences for Hb as periodontal screening test. We performed a literature search of report published using PubMed databases. A total of 55 articles were retrieved and 16 were selected. Our review focuses on corelation coefficient with periodontal clinical parameters or sensitivity and specificity. As a result, fourteen studies calculated sensitivity and specificity of Hb. Six studies measured salivary levels hemoglobin at laboratory: three studies used polyclonal antibody reactions and other studies used colorimetric tests. Eight studies used paper strip method: 4 studies used monoclonal antibody reaction and 4 studies used colorimetric tests. Youden’s indexes by antibody reaction were better than those of colorimetric methods. Evidences are described above and further studies are necessary to set the cut off values stratified by gender, age and number of remaining teeth.

  • Dentigerous Cystic Changes in the Follicles Associated with
           Radiographically Normal Impacted Mandibular Third Molars

    • Abstract: Objective. To assess the incidence of dentigerous cystic changes in the follicles of radiographically normal impacted mandibular third molars. Methods. One hundred and thirteen follicles obtained after surgical removal of impacted mandibular third molars with radiolucency of less than 2.5 mm in the radiograph were sent for histopathologic evaluation to evaluate pathologic changes. Results. The incidence of dentigerous cystic changes observed was 15.9%, that is, 18 out of 113 patients (51 males and 62 females), with the maximum incidence of cystic changes seen in the follicular space size of 0.5 mm. The mean age of the patients included was 27.8 ± 8.1. The most common indication for extraction among the patients in this study was recurrent pericoronitis (95%). There were no statistically significant differences in occurrence of cystic changes based on age, gender, angulation, relation to ramus, depth, side of impaction, and follicle size (). Conclusion. Dental follicles obtained from surgically removed impacted mandibular third molars should be submitted for histopathologic examination irrespective of the radiographic size of the follicle.

  • Oral Health Status of Syrian Children in the Refugee Center of Melilla,

    • Abstract: Introduction. Little is known about the state of oral health among immigrants from conflict zones, such as the refugee children from the Syrian Civil War. Aim. To determine the oral health status of Syrian immigrant children refugee at the Center for Temporary Stay of Immigrants in Melilla to plan prevention and care programs. Design. Using the criteria set by the World Health Organization, an exploration of the oral cavity of all Syrian children aged 5–13 living at that center was conducted in May 2015. All subjects were clinically evaluated by a calibrated and standardized examiner, accompanied by a dentist who registered the clinical variables, and translators. The sociodemographic and clinical variables were analyzed through a descriptive and analytical study, respectively. Results. The prevalence of caries in both the permanent and deciduous dentition was 75% and 50% in 6- and 12-year-olds, respectively. The dft was 3.2 ± 2.9 in 6-year-old children. At 12 years old, the DMFT was 1.6 ± 2.6 teeth, the DMFM was 1.1 ± 1.7 teeth, the SiC was 3.2, and the IR was 5%. Eighty-six percent of the examined sextants were periodontally healthy. Conclusions. The prevalence of caries was high in the sample population studied, confirming the need for a comprehensive primary oral health care program.

  • Preferred Source and Perceived Need of More Information about Dental
           Implants by the Undergraduate Dental Students of Nepal: All Nepal Survey

    • Abstract: Objectives. This study was conducted to know the preferred source and perceived need of more information about dental implants by the undergraduate students of Nepal and their association with academic levels and gender. Materials and Methods. It was conducted in all the dental colleges of Nepal from June 2016 to June 2017 after taking ethical clearance and approval from the research committee of BPKIHS. It included all those who were present at the time of survey. Data collection was done through a cross-sectional questionnaire survey during the academic schedule of the colleges, supervised and monitored by the investigators themselves. The collected data were coded and entered in Microsoft excel 2013, and statistical analysis was done by SPSS 20 version. Result. A majority of the respondents agreed that they were not provided with sufficient information about implant treatment procedures during their BDS program (65.3%), would like more to be provided in the curriculum (95.1%), and would like to get additional reliable information from dental consultants and specialists (40.7%) and training on it from fellowship programs conducted by universities (39.2%). Significant association was seen between the responses and academic levels. Conclusion. Undergraduate dental students of Nepal want more information about dental implants through various means.

  • ElectromyoFigureic Evaluation of Functional Adaptation of Patients with
           New Complete Dentures

    • Abstract: Objective. The objective of this study was to evaluate the level of adaptation of patients to newly fitted complete dentures in their dominant and nondominant sides, by means of ElectromyoFigureic signals. Materials and Methods. Eighty-eight patients with complete dentures were evaluated in the study. Masticatory muscle (masseter and temporal) bioelectric activity of the patients with complete dentures was recorded at maximum intercuspal relation. Parametric statistical data were analyzed with one-way repeated measures ANOVA test. Results. Measurement time was significantly different for both dominant (DS) and nondominant (NDS) sides: FΣs-DS = 21.51, ; FΣs-NDS = 13.25, . Gender was also significantly different: FΣs-DS-gender = 41.53, ; FΣs-NDS-gender = 85.76, . The average surface area values showed significant difference in females. Prior experience with dentures showed no significant difference for both sides of mastication: FΣs-DS-experiences = 1.83, ; F Σs-NDS-experiences = 3.30, .Conclusion. The planimetric indicators of bioelectric activity of masseter and temporalis muscles at maximum physiological loading conditions are significant discriminators of the level of functional adaptation of patients with new complete dentures.

  • Deciphering Possible Association of Risk Factors for Dental Caries in
           Pakistani Population

    • Abstract: Obesity is a state of abnormal accumulation of fat in adipose tissues of the body to the level that one’s health is adversely compromised. Tripathi et al. state (according to WHO) that obesity is now considered the fifth leading cause of mortality in the world. Caries is a multifactorial disease and one of the major oral health issues of the modern era affecting people around the globe. Rise in dental caries has been observed in developing countries as a result of factors including increased intake of carbohydrates. The present study aims for assessing the association of DMFT with BMI, age, and gender. This study was conducted in the dental OPD of the Dow University of Health Sciences, Karachi, from February 2016 till January 2017. A custom-made interview-based questionnaire was used to assess BMI, DMFT, and sociodemographics. The sample size was kept at 385. Age was reported as a strong predictor (R2 0.641) of DMFT followed by BMI and gender as the weakest predictors. Age and BMI had statistically significant association with DMFT scores, which shows that diet patterns may affect general health. High caloric intake over long periods affects BMI and also oral health.

  • Variation of Energy in Photobiomodulation for the Control of
           Radiotherapy-Induced Oral Mucositis: A Clinical Study in Head and Neck
           Cancer Patients

    • Abstract: Oral mucositis (OM) is a frequent and severe adverse effect of therapy against head and neck cancer. Photobiomodulation with the low-power laser is known to be effective against OM, but the diversity of protocols and the possibility of stimulating residual tumor cells are still obstacles. The present study aimed to compare two doses of laser energy delivered to the oral mucosa of patients under oncologic treatment for head and neck cancer, looking for differences in the control of mucositis, as well as in the frequency of tumoral recurrences. Fifty-eight patients undergoing radiotherapy were randomized into two groups, distinguished according to the energy delivered by laser irradiation, namely, 0.25 J and 1.0 J. The groups were compared according to frequency, severity, or duration of OM, as well as the frequency of tumoral recurrences. OM was significantly less frequent in patients receiving 1.0 J of energy, but the groups did not differ regarding severity or duration of OM. Tumoral recurrence also did not vary significantly between the groups. Photobiomodulation with a higher dose of energy (1.0 J versus 0.25 J) is associated with better control of radiotherapy-induced OM and does not significantly increase the risk of neoplastic recurrence.

  • Dental Arch Dimensions in Saudi Adults

    • Abstract: Objective. The aim of this study was to investigate the arch dimensions (width, length, and depth) in Saudi Arabia. Materials and Methods. 169 orthodontic models (73 males and 96 females) made of white stone were selected according to inclusion criteria. Measurement of arch dimensions was taken including width, length, and depth at different reference points. Differences between males and females were tested using independent samples t-test. Results. The sample comprised subjects aged 18–33 years old. Most measurements showed higher values for males compared to females. Saudi males showed smaller intercanine widths compared to Caucasians and Southern Chinese but larger widths in females compared to Caucasians and smaller widths compared to Southern Chinese. Saudi males and females showed larger intermolar widths compared to Caucasians but smaller intermolar widths compared to Southern Chinese. For arch length, Saudis showed longer arches compared to Yemenis for both males and females but smaller palatal depths compared to Yemenis. Conclusions. Differences in intercanine width, intermolar width, and palatal length and depth were found between Saudis and other nationalities. Male and female participants had differences in most of the measurements.

  • Oral Cancer Knowledge Assessment: Newly Graduated versus Senior Dental

    • Abstract: The present study assessed the level of dentists’ knowledge regarding oral cancer in the city of São Paulo, Brazil. A questionnaire was used to compare the level of knowledge among newly graduated and senior clinicians. A total of 20,154 e-mails were correctly delivered to the dentists registered in the database of the Regional Dentistry Council of São Paulo, and 477 (2.36%) responses were received. This sample consisted of 84 newly graduated clinicians and 105 senior clinicians. For the statistical analysis, the chi-square test and the logistic regression analysis were performed with α = 0.05, and the results were described herein. According to their knowledge level, the results were statistically different between the groups, since 19% of the newly graduated clinicians were evaluated with knowledge grade A (excellent) in comparison to 6.7% of the senior clinicians. In spite of the results indicated that newly graduated clinicians’ knowledge regarding oral cancer was 2.1 times higher, 34.5% of the professionals in this group had regular or poor knowledge on the subject, and several questions relating to clinical characteristics and risk factors indicated that there still exist some knowledge gaps, demonstrating that there is a need for further studies and information activities addressing oral cancer.

  • Oral Health of Lipjan Convicts: Kosovo Prison House

    • Abstract: Objectives. The oral health services of the prison population are considered more complex than those of the general population. The aim of this study was to examine the oral health status (the DMFT index and OHI index) and to evaluate the relation between the oral health and risk factors of inmates of this population, thus identifying the dental health status of inmates by gender, age, and the duration of their sentence. Materials and Methods. Our study has included a total number of 150 inmates, of both genders, from Lipjan prison house in Kosovo. Results. Oral health condition of inmates in Lipjan prison house is severe; the average value of DMFT is 8.44: for minors 6.22, while for adults 9.55. The assessment of DMFT index within the recruited inmates in our study shows that the mean rate of oral cure was 3.21, while the mean extraction value and caries were 3.55 and 3.58, respectively. The mean plaque test value was 1.44. Conclusion. Based on this research, we have concluded that the oral health condition of the inmates in Lipjan prison is not good, due to the presence of different risk factors among them.

  • The Prevalence and Underreporting of Needlestick Injuries among Dental
           Healthcare Workers in Pakistan: A Systematic Review

    • Abstract: Needlestick injuries (NSIs) are a major occupational health problem among dental healthcare workers (HCWs) in Pakistan, which places them at a significant risk of acquiring blood-borne infections. However, not all NSIs are reported, leading to an underestimation of the actual prevalence. The harmful impacts of NSIs on the healthcare delivery necessitate an urgent need to measure its actual prevalence. Objectives. The aim of this study was to review literature to estimate the prevalence and reporting rates of NSIs among dental-HCWs in Pakistan. Methods. 713 potentially relevant citations were identified by electronic databases and hand searching of articles. Nine primary studies were subsequently identified to be included in the review. Results. The results of the included studies indicate that the prevalence of NSIs among Pakistani dental-HCWs was between 30% and 73%. The rate of reporting of NSIs was between 15% and 76%, and the most common reason was found to be the lack of awareness regarding the reporting system, or of the need to report NSIs. Conclusion. It is evident from the review of the included studies that there is a significantly high prevalence and a low rate of reporting of NSIs among dental-HCWs in Pakistan, suggesting the need to setup an occupational health department in dental settings, for preventing, managing, recording, and monitoring NSIs.

  • Comparative Analysis of the Effectiveness of the Topical Administration of
           Benzocaine and EMLA® on Oral Pain and Tactile Sensitivity

    • Abstract: Objectives. To compare the effectiveness of the topical administration of benzocaine and EMLA on oral pain and tactile sensitivity. Materials and Methods. A randomized, double-blind, split-mouth clinical trial was carried out with 20 volunteers. The sensorial and quantitative tests were applied before the contact with topical anesthetic and after the application. Results. In the superficial tactile perception test, when we compared each group singly, there were statistically significant values in the decrease of superficial tactile perception when compared to the moment prior to the application of anesthetic agents. For the sensitivity to mechanical pain, no statistical significant difference was observed at evaluated times. In the needle penetration test, in an intergroup analysis, we found a decrease in the pain sensitivity to needle penetration at 5 min () and at 10 min () after the contact of the anesthetic drug with the oral mucosa. Conclusion. The application of topical anesthetic drugs reduces the discomfort associated with this procedure, mainly until the first 10 minutes. Only the needle penetration sensitivity test showed sufficient sensitivity to reveal a difference in the anesthetic effect between EMLA and benzocaine. This trial is registered with RBR-2N2GSW.

  • Self-Assembled Monolayers for Dental Implants

    • Abstract: Implant-based therapy is a mature approach to recover the health conditions of patients affected by edentulism. Thousands of dental implants are placed each year since their introduction in the 80s. However, implantology faces challenges that require more research strategies such as new support therapies for a world population with a continuous increase of life expectancy, to control periodontal status and new bioactive surfaces for implants. The present review is focused on self-assembled monolayers (SAMs) for dental implant materials as a nanoscale-processing approach to modify titanium surfaces. SAMs represent an easy, accurate, and precise approach to modify surface properties. These are stable, well-defined, and well-organized organic structures that allow to control the chemical properties of the interface at the molecular scale. The ability to control the composition and properties of SAMs precisely through synthesis (i.e., the synthetic chemistry of organic compounds with a wide range of functional groups is well established and in general very simple, being commercially available), combined with the simple methods to pattern their functional groups on complex geometry appliances, makes them a good system for fundamental studies regarding the interaction between surfaces, proteins, and cells, as well as to engineering surfaces in order to develop new biomaterials.

  • Effect of Glazing on Flexural Strength of Full-Contour Zirconia

    • Abstract: Objective. The purpose of this study was to evaluate the effect of glazing on flexural strength of highly translucent zirconia materials. Materials and Methods. Specimens of three brands of zirconia bars (Prettau Zirconia, Zirkonzahn; inCoris TZI, Sirona; and Zirlux FC, Pentron Ceramics) were prepared and polished according to manufacturers’ instructions. Final specimen dimensions were 20 × 4 × 2 mm. The specimens from each brand were divided into 3 groups (N = 10): control, heat-treated, and glazed. Heat-treated specimens were fired without the application of the glaze material. The glaze material was applied to the glazed specimens before being fired. A three-point bending test (15 mm span) was performed in an Instron universal testing machine (ISO 6872). Data were analyzed by ANOVA and Tukey’s HSD post hoc test (α = 0.05). Results. Two-way ANOVA showed a significant influence of surface treatments on flexural strength of zirconia materials (). There was no significant difference in flexural strength among the different brands of highly translucent zirconia (). Tukey’s HSD post hoc test showed that specimens in the “glazed” group had significantly lower flexural strength than the control and heat-treated groups (). Conclusion. Within the limitations of the study, external glazing decreased the flexural strength of highly translucent zirconia.

  • Double Guided Surgery in All-on-4® Concept: When Ostectomy Is Needed

    • Abstract: Background. The rehabilitation of edentulous jaws with guided and flapless surgery applied to the All-on-4 concepts is a predictable treatment with a high implant and prosthetic survival rates, but there are several contraindications for this technique like when bone reduction is needed due to a high smile line in the maxilla or when there is an irregular or thin bone crest. Purpose. To report a technique with double guided surgery for bone reduction and implant placement with the All-on-4 concept. Materials and Methods. 7 patients were included in the study. Guided implant planning was performed using CBCT, and the virtual templates were created with three dedicated software. Custom surgical templates were made for the ostectomy and for implants positioning. Results. 28 implants were placed using a double bone-supported surgical guide. The mean angular errors between the preoperative-planned implant and the postoperative-placed implant were 2.155° ± 2.03°; the mean distance errors between the planned and the placed implants were 0.763 mm ± 0.55 mm on the shoulder implant and 0.570 mm ± 0.40 mm on the apex implant. Conclusions. The results of our study indicate that this treatment is predictable with an excellent survival rate allowing excellent results even when bone reduction is mandatory.

  • Shisha Smoking Habit among Dental School Students in the United Arab
           Emirates: Enabling Factors and Barriers

    • Abstract: Objectives. The objective of the present study was to assess shisha smoking among dental school students in Sharjah, United Arab Emirates (UAE). In addition, the role of suggested barriers and enabling factors in shisha smoking was also evaluated. Methods. A cross-sectional questionnaire-based survey was conducted at the College of Dental Medicine, University of Sharjah, between February and May 2016. The questions were adapted from previously published water pipe smoking studies. The collected data were analyzed to identify the relationship between shisha smoking and sociodemographic characteristics. Relevant questions were further categorized as enabling factors and barriers for shisha smoking. Results. Three enabling questionnaire items related to social environment were significantly associated with an increased risk of being a current smoker. The most powerful is peer pressure (“friends smoke shisha”), which increased the odds ratio of shisha smoking 11.3 times, followed by smoker sibling with increase in odd ratio by 4.52 times, then the belief of social acceptance with increase in odd ratio by 4.31 times. Conclusion. Shisha smoking is a serious problem among university students. Any intervention program in the university curricula should consider teaching students that shisha is no less risky than cigarettes and is addictive.

  • Soft Lithography and Minimally Human Invasive Technique for Rapid
           Screening of Oral Biofilm Formation on New Microfabricated Dental Material

    • Abstract: Introduction. Microfabrication offers opportunities to study surface concepts focused to reduce bacterial adhesion on implants using human minimally invasive rapid screening (hMIRS). Wide information is available about cell/biomaterial interactions using eukaryotic and prokaryotic cells on surfaces of dental materials with different topographies, but studies using human being are still limited. Objective. To evaluate a synergy of microfabrication and hMIRS to study the bacterial adhesion on micropatterned surfaces for dental materials. Materials and Methods. Micropatterned and flat surfaces on biomedical PDMS disks were produced by soft lithography. The hMIRS approach was used to evaluate the total oral bacterial adhesion on PDMS surfaces placed in the oral cavity of five volunteers (the study was approved by the University Ethical Committee). After 24 h, the disks were analyzed using MTT assay and light microscopy. Results. In the present pilot study, microwell structures were microfabricated on the PDMS surface via soft lithography with a spacing of 5 µm. Overall, bacterial adhesion did not significantly differ between the flat and micropatterned surfaces. However, individual analysis of two subjects showed greater bacterial adhesion on the micropatterned surfaces than on the flat surfaces. Significance. Microfabrication and hMIRS might be implemented to study the cell/biomaterial interactions for dental materials.

  • The Role and Impact of Salivary Zn Levels on Dental Caries

    • Abstract: Introduction. Minimal attention has been given to the role of salivary microelements, the importance they have in reducing the intensity of caries, and the effect of caries prophylaxes. Aim. This research aimed to determine the concentration and quantity of Zn and its impact on the prevention and the reduction of the intensity of caries in schoolchildren aged 12-13 years with permanent dentition. Methods. For this research, we analyzed the stimulated and nonstimulated full saliva of 106 schoolchildren divided into three groups by mean decayed, missing, and filled teeth (DMFT) index. The control group consisted of 25 caries-free children, the second group had 47 children with mean DMFT index of 1 to 6, and the third group had 34 children with DMFT index of ≥ 6. Complete saliva was collected from all children in a sterile test tube. Results. The concentration of Zn in saliva before stimulation in caries-free children has variations of the order of 0.001+ to 0.01 mmol/l. The maximum concentration after stimulation is 6.72 mmol/l, while the maximum value is 64.38 mmol/l. Conclusion. The Zn concentration in the stimulated saliva showed a significant increase in the group of caries-free children and could be described as a positive value for the reduction of caries.

  • Application of D-Amino Acids as Biofilm Dispersing Agent in Dental Unit

    • Abstract: Aim and Purpose. Biofilms in dental unit waterlines (DUWLs) are extremely difficult to eliminate. Aim of this study is to evaluate the efficacy of a mixture of four D-amino acids on biofilm dispersion in DUWLs. Materials and Methods. A mixture of four D-amino acids (D-methionine, D-tryptophan, D-leucine, and D-tyrosine, 10 mM each), distilled water (control), and 0.1 M hydrochloric acid (HCl) was used in the experiment. In laboratory, pieces of DUWLs covered with biofilms were submerged in different solutions for 5 days, flushed, and measured OD600 of the dispersed biofilms. Remnants of biofilms on the DUWLs were evaluated by SEM. In clinic, fifteen DCUs were incubated with test and control solutions, flushed, and measured OD600 of the dispersed biofilms. Microbial count of DUWL output water was enumerated twice a week for four weeks. Results. There was a slight, but not significant, increase in OD600 of flushing water in D-amino acids group. D-amino acids effectively reduced bacterial plaque as demonstrated by SEM. Incubation with D-amino acids significantly reduced biofilms especially after the first day of flushing. Bacterial count in DUWL output water was significantly reduced after treatment with D-amino acids. Conclusion. D-amino acids are applicable as biofilm dispersing agents in DUWLs.

  • Osseointegration of a 3D Printed Stemmed Titanium Dental Implant: A Pilot

    • Abstract: In this pilot study, a 3D printed Grade V titanium dental implant with a novel dual-stemmed design was investigated for its biocompatibility in vivo. Both dual-stemmed (n = 12) and conventional stainless steel conical (n = 4) implants were inserted into the tibial metaphysis of New Zealand white rabbits for 3 and 12 weeks and then retrieved with the surrounding bone, fixed, dehydrated, and embedded into epoxy resin. The implants were analyzed using correlative histology, microcomputed tomography, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The histological presence of multinucleated osteoclasts and cuboidal osteoblasts revealed active bone remodeling in the stemmed implant starting at 3 weeks and by 12 weeks in the conventional implant. Bone-implant contact values indicated that the stemmed implants supported bone growth along the implant from the coronal crest at both 3- and 12-week time periods and showed bone growth into microporosities of the 3D printed surface after 12 weeks. In some cases, new bone formation was noted in between the stems of the device. Conventional implants showed mechanical interlocking but did have indications of stress cracking and bone debris. This study demonstrates the comparable biocompatibility of these 3D printed stemmed implants in rabbits up to 12 weeks.

  • The Effect of Number of Teeth and Chewing Ability on Cognitive Function of
           Elderly in UAE: A Pilot Study

    • Abstract: Cognitive decline is one of the major causes of disability among the aging population. The aim of this study was to explore the relationship between oral health parameters (number of teeth, chewing ability, and presence of a denture) and cognitive function in the elderly across the UAE. Fifty persons (age ≥ 60; 71.26 ± 10.23) were enrolled in the study. Cognitive status was assessed using the standardized mini-mental state examination (SMMSE) and accordingly, cognitively normal subjects scoring ≥24 were considered as the control group and cognitively impaired individuals scoring ≤23 were considered as the low scoring group. Chewing ability was examined, number of teeth was noted, and demographical data was collected. The results of this pilot study showed that individuals with low SMMSE scores were significantly less educated () and had fewer number of remaining teeth () and impaired chewing ability (). These results demonstrate a significant link between the number of teeth, chewing ability, and cognitive function. However, this pilot study had its limitations and was the first of its kind in the UAE and Gulf region; therefore, future research addressing the limitations is needed to further explore this association.

           Minor Aphthae: A Prospective, Parallel, Double Blind, Active Control,
           Preliminary Study

    • Abstract: Background and Objectives. Recurrent aphthous stomatitis is an inflammatory condition present since ancient era wherein numerous treatment modalities have been tried. But complete eradication of the disease has not been possible and hence newer agents are being introduced. One such agent is a flavonoid named quercetin with proven antioxidant, anti-inflammatory, and ulcer healing properties. Methods. 40 patients with minor aphthous ulcers were divided equally into two groups: A and B. Group A patients were advised to apply quercetin gel and Group B patients were advised to take benzydamine hydrochloride mouth wash. Clinical evaluation including assessment of ulcer size and pain score and questionnaire about the acceptability of both the drugs in terms of taste and ease of application was carried out. Each criterion was compared and statistically analyzed. Results. There was statistically significant reduction in the mean score of pain sensation and ulcer area in both the groups. Quercetin showed statistically highly significant ulcer size reduction as compared to benzydamine hydrochloride. Conclusion. From the present study, it is evident that quercetin is safe, well tolerated, and effective therapy which promotes complete ulcer healing in a short duration of time.

  • A Competition between Care Teams Improved Recording of Diagnoses in
           Primary Dental Care: A Longitudinal Follow-Up Study

    • Abstract: Introduction. A playful competition was launched in a primary dental health care system to improve the recording of diagnoses into an electronic patient chart system and to study what diagnoses were used in primary dental care. Methods. This was a longitudinal follow-up study with public sector primary dental care practices in a Finnish city. A one-year-lasting playful competition between the dental care teams was launched and the monthly percentage of dentists’ visits with recorded diagnosis before, during, and after the intervention was recorded. The assessed diagnoses were recorded with the International Classification of Diseases (ICD-10). Results. Before the competition, the level of diagnosis recordings was practically zero. At the end of this intervention, about 25% of the visits had a recorded diagnosis. Two years after the competition, this percentage was 35% without any additional measures. The most frequent diagnoses were dental caries (K02, 38.6%), other diseases of hard tissues of teeth (K03, 14.8%), and diseases of pulp and periapical tissues (K04, 11.4%). Conclusions. Commitment to the idea that recording of diagnoses was beneficial improved the recording of dental diagnoses. However, the diagnoses obtained did not accurately reflect the reputed prevalence of oral diseases in the Finnish population.

  • Superfast Set, Strong and Less Degradable Mineral Trioxide Aggregate

    • Abstract: Purpose. Despite the good sealing ability and biocompatibility of mineral trioxide aggregate (MTA), its slow setting, high degradation, and weakness limit its use in surgical endodontics and high stress-bearing areas. This study aimed to develop two new liquids to control these drawbacks. They were prepared from calcium chloride, fumed silica, and hydroxyapatite or calcium phosphate and coded “H” and “P,” respectively. Methods. Portland cement, Grey ProRoot® MTA, and white ProRoot MTA were mixed with distilled water (control) or liquid “H” or “P.” The pH, setting time, degradation rate, leachant/precipitate’ composition, compressive strength, and morphology were assessed. Results. Both liquids maintained MTA’s high alkalinity and reduced the setting time by 1-2 orders of magnitude. Both liquids, H in particular, significantly reduced the degradation rate of Grey ProRoot and White ProRoot MTA®. Calcite has been identified as the main phase of the leachant or precipitate formed during the cement’s degradation. Calcium hydroxide or hydroxyapatite was also identified with Grey ProRoot MTA mixed with H liquid. These liquids also significantly increased the compressive strength with no statistical differences between them; this was associated with the production of dense, consolidated structures. Conclusions. The modified MTA could be used in surgical endodontics and high stress-bearing areas.

  • Antibacterial Effects of Natural Herbal Extracts on Streptococcus mutans:
           Can They Be Potential Additives in Dentifrices'

    • Abstract: Background. Many plants or herbs exhibit potent antimicrobial activity against various microorganisms. They have no side effects and presumably act against and modulate the factors that are crucial for microbial survival or their activity. Streptococcus mutans is a pioneer bacteria implicated in dental caries. This study aims to evaluate the antimicrobial activity of garlic bulbs, pudina leaves, and mango and eucalyptus twig extracts on Streptococcus mutans by evaluating their zone of inhibition and determining their minimum inhibitory concentration (MIC). Methods. Microbiological assay (well diffusion method) to determine zone of inhibition against pure forms of Streptococcus mutans was performed. The antibacterial effects of methanolic extracts of mango twigs, eucalyptus twigs, pudina leaves, and garlic bulbs were studied. Test compounds were further evaluated for their MIC. Results. Extracts derived from mango and eucalyptus twigs showed significant antibacterial effects at test concentrations. Pudina and garlic extracts did not show any significant antibacterial effects at similar concentrations. Upon further evaluation of the 2 positive compounds for their MIC, mango twigs demonstrated more antimicrobial potential than eucalyptus twigs at a lower concentration. Conclusion. Our observations indicated that the mango twig extracts possess higher antibacterial effects against Streptococcus mutans than other compounds at specific test concentration.
