Objectives: This case-control study aimed to compare patients with temporomandibular disorders (TMD) and healthy controls in terms of oral health-related quality of life (OHRQoL) considering Graded Chronic Pain Scale (GCPS) scores, pain duration, psychological impairment and demographic characteristics.Methods: A total of 75 patients with TMD and 75 healthy controls were recruited. The short version of Oral Health Impact Profile (OHIP-14) was administered for evaluating the OHRQoL. Psychosocial impairments were assessed using the General Health Questionnaire-28 (GHQ-28). The Research Diagnostic Criteria for TemporomandibularDisorders (RDC/TMD) axis I and II were also used for patient diagnosis and collecting GCPS scores, pain duration, age and gender. Independent-sample t tests, Pearson's chi-square tests and multiple logistic and linear regression models were applied for statistical analysis. Results:The mean age of the patients was 34.3±12.4 years. A female-to-male ratio of 6:1 was seen in the TMD group. The prevalence and severity of the OHIP were significantly different between the TMD and control groups (66.7% vs 12.0% and 18.0 vs 9.2, respectively). According to multiple logistic regression for OHIP prevalence and multiple linear regression for OHIP severity in the TMD group, GCPS scores and pain duration, followed by psychological impairment, were the most important predictors of the OHRQoL. Conclusion:TMD negatively affected the OHRQoL, particularly in patients with psychological impairments. Meanwhile, age and gender did not seem to have a serious effect. Hence, promoting the quality of life of patients with TMD requires emphasis on chronic pain management and maintaining good mental health.

BACKGROUND: Propolis is a resinous substance obtained from the beehives that has antioxidant, anti-bacteria, anti-virus, antifungal, anti-tumor and anti-inflammatory activity. The aim of this study was to review the studies about the role of propolis in improving dental and oral health.METHODS: This study reviewed the published articles regarding the applications of propolis in dentistry. An electronic search of the literature was carried out in Farsi electronic databases includingGoogle, Medlib.ir, SID, Iranmedex and Magiran as well as English electronic databases such as PubMed and ISI Web of Knowledge.These databases were searched for articles published between 1997and October 20, 2017. Non-dental books and journals were also manually searched.RESULTS: This study reviewed published articles on the efficacy of propolis for surgical wound healing, caries prevention, treatment of dentin hypersensitivity, treatment of aphthous ulcers and propolis as a storage medium for avulsed teeth, root canal irrigating solution and mouthwash.CONCLUSION: The result of the reviewed article showed that propolis is effective an agent that is used for multiple purpose in oral health.KEYWORDS: Propolis, Dentistry, Honeybee, Oral health

The study assessed the need for revision surgery and the relating factors in alveolar cleft autogenous bone grafting in patients with complete cleft. It was a retrospective study carried out in 2009. The medical records of the 54 patients with alveolar cleft who underwent autogenous bone grafting in the maxillofacial department in Shariati Hospital from 2005 to 2008 were studied. The patients' age, sex, cleft type, age at palatal and alveolar clefts repair, tooth missing, surgery turn, and presence of orthodontic treatment were assessed. The patients' alveolar bone height was evaluated from their postoperative and follow-up panoramic radiographs. In general, 41% (n = 22) of patients needed revision surgery. Among all patients, 20 (37%) had secondary bone grafting and 34 (63%) had tertiary bone grafting. For 77% of the secondary unilateral clefts and 71% of bilateral ones, the remaining bone was at least three-fourths of the normal. Logistic regression model controlling for grafting time, surgery turn, orthodontic supervision, and age at palatal cleft closure showed that orthodontic treatment is associated with a lower need for revision surgery (odds ratio = 0.3; 95% confidence interval, 0.1-1.0). In conclusion, although alveolar cleft bone grafting is necessary for the reconstruction of the complete clefts, all these patients must be under the supervision of orthodontists to benefit from the surgical treatment.

Received: October 2017, Accepted: April 2017 Background: One of the most important epidemiologic indices for the assessment and measurement of dental caries is the Decayed, Missing, and Filled Teeth (DMFT) index which is used as an important criterion for the evaluation of the oral and dental health status of individuals. Therefore, the present study was conducted to determine DMFT6 (DMFT of the first permanent molar) index and the related factors with the caries free status in students of 12 years of age in Larestan, Iran, in 2014. Materials and Methods:The present cross-sectional survey was conducted on 2436 students. Data were collected using the National Oral Health Promotion Plan Checklist. If the features of decayed, missing, and filled were observed in any of the first permanent molars, they received a score of 1. Data were analyzed using chi-square test, chi-squared test for trend, independent two-sample t-test, and multiple logistic regression model. Results: The mean and standard deviation of DMFT6 in all students was 1.00 ± 1.36. It was 1.07 ± 1.39 and 0.93 ± 1.33 in girls and boys, respectively, and this difference was statistically significant (P = 0.0080). In addition, more than half of the students (51.5%) were caries free. The variables of gender (P = 0.0007), mothers' education (P < 0.0001), and fathers' occupation (P = 0.0045) were determined as the related factors of the caries free variable in the logistic regression model. Conclusions: It seems that the amount of the DMFT6 index in students of 12 years of age in Larestan was high compared to the World Health Organization (WHO) standards in 2010. Therefore, it is recommended that efficient plans be made to promote the oral and dental health of students.
