Abstract
Background and Aims: The oral impact on daily performance (OIDP) is one of the oral health-related quality of life indices to measure physical, social and mental consequences of the oral health status. This study aimed to evaluate the OIDP index in patients referring to Tehran dental school.
Materials and Methods: Four hundred and ninety nine patients referring to patients' clinic in Dental School of Tehran University of Medical Sciences in spring 2011 participated in this study. They were interviewed for demographic factors including age, gender and level of education, and OIDP index questionnaire before receiving any treatment. Statistical analysis was carried out by means of linear regression modeling.
Results: 85.6% of patients confirmed that they had at least one oral impact on daily performance during the last 6 months. The most prevalent performances affected were eating (50.1%) and smiling and showing teeth without shame (12.8%). The mean OIDP score for the population was 5.6 ranging from 0 to 36. Linear regression modeling controlling for age, gender and years of education revealed that older patients and those with lower education had significantly higher OIDP scores.
Conclusion: The effect of oral health on daily performance was clear. The association among age, education and oral impact on daily performance indicates the need for more comprehensive preventive oral health care for adults with lower educational level.

Abstract
Background and Aims: This study was conducted to assess the psychological health status of dentists in Shiraz city.
Materials and Methods: In this cross-sectional study, subjects consisted of 106 dentists and 94 general practitioners (comparison group) from private and public clinics in Shiraz city. Subjects were requested to complete the standard general health questionnaire and a questionnaire on demographic variables. The data were analyzed by appropriate statistical tests. Chi-Square test and independent sample t-test were used to compare demographic and occupational variables of both groups. The questionnaires were scored and the overall score of each individual determined his/her psychological health status. Means of GHQ scores of both groups were compared using statistical tests.
Results: Both groups were similar in all demographic variables, except for age. The mean total score of GHQ-28 for both dentists (17.9) and physicians (16.34) groups were significantly lower than the cut-off point value of 23 (P <0.01). The means of scores for somatic problems, depression, anxiety and insomnia as well as unusual social performance scales were significantly different between both groups (P<0.05). A significant positive association was found between GHQ total score and job tenure.
Conclusion: Our findings revealed that psychological health status of dentists was poorer than that of physicians. Additionally, dentists' scores were significantly different from those of their counterparts in all GHQ sub-scales.

Abstract
Background and Aims: Apoptosis or programmed cell death plays an important role in the pathogenesis of many diseases. Previous studies suggest that apoptosis is involved in the pathogenesis of periodontal disease, on the other hand it is also suggested that diabetes mellitus enhances apoptosis of connective tissue cells. Thus, we measured expression of proteins which are relevant to apoptosis in the gingival tissue of diabetic patients with chronic periodontitis in comparison to non diabetic individuals.
Materials and Methods: 25 patients with diabetes and chronic periodontitis and 16 non diabetic controls were included in this study. 4 weeks after scaling and root planning and oral hygiene instructions, periodontal surgery was done and gingival tissues obtained during surgery, were sent to lab to investigate expression of Fas, P53, Bcl-2 and Survivin using real-time PCR technique. Data were analyzed using Mann-Whitney and Chi-squared.
Results: Pro-apoptotic proteins (Fas, P53) were significantly (P<0.05) higher in gingival tissues of diabetics (9.5×10-6, 2.4×10-6, respectively) in comparison to non diabetics (9.4×10-7, 5.6×10-7), whereas the difference in expression of anti-apoptotic proteins (Bcl-2, Survivin) between 2 groups was not significant (9.7×10-8, 3.5×10-7 in comparison to 1.4×10-7, 3.1×10-7, respectively)( P =0.91, P =0.29 respectively).
Conclusion: Apoptosis was increased in gingival connective tissue of diabetic patients with chronic periodontitis in comparison to non diabetic ones. Therefore , intervention in expression or function of pro-apoptotic proteins (Fas, P53) could be a new goal in the treatment of periodontal disease of diabetic patients.

Abstract
Background and Aims: Considering the complications of root canal system, debridement would not be effective only by mechanical instrumentation. Therefore, root canal irrigants with the antimicrobial effect that can eliminate more microorganisms during treatment, becomes important. The aim of this study was to compare the antimicrobial effects of 2% thyme essence, 2.5% sodium hypochlorite (NaClO), and normal saline as root canal irrigants for primary molar teeth.
Materials and Methods: This study was performed on 34 primary molars. Subjects were randomly divided into three groups (N=10). The root canals of the teeth were prepared up to the file #35 and all of the specimens were sterilized, and were then contaminated with entrococccus faecalis suspension (Enterococcus Faecalis ATTC 29212). After 48 hours of incubation, the specimens of each group were irrigated with corresponding irrigants. Then, the microbial specimens were collected with sterile paper points. After incubation, the numbers of Colony Forming Units (CFU) were counted using colony counter. Data were analyzed using Smirnov-Kolmogorov, Kruskal-Wallis and Mann-Whitney tests.
Results: Sodium hypochlorite showed the highest antimicrobial effect and showed significant differences compared with normal saline (P<0.001). However, the differences were not significant with thyme essence 2% (P=0.3).
Conclusion: Thyme essence could be considered as a natural irrigator with a comparable antiseptic effect to sodium hypochlorite.

Abstract
Background and Aims: Postoperativee endodontic pain is an outstanding problem for dental patients. Therefore, a successful management of endodontic pain has become as one of the main dental objectives. The aim of the present study was to compare the postoperative endodontic pain in patients under general anesthesia versus local anesthesia.
Materials and Methods: For conducting this clinical trial study, 50 patients having mandibular molars candidate for root canal therapy were selected. Twenty-five patients treated under general anesthesia because of their fear, anxiety or gag reflex. Other 25 patients treated under local anesthesia. All teeth were prepared using engine-driven rotary system in a crown-down technique and filled using lateral condensation technique. Heft- parker visual analog scale was used to measure the degree of pain at 6, 12, 24, and 48 hours after the treatment. Mann-Whitney, Chi-square, and T-tests were used to compare the intensity of postoperative pain between the groups.
Results: The mean intensity of postoperative pain in local and general anesthesia groups at 6, 12 and 24 hours had statistically significant difference (P<0.05).
Conclusion: Postoperative pain in patients who treated under general anesthesia was significantly less than the patients who treated under local anesthesia.

Abstract
Background and Aims: Dental students’ evaluation of teachers’ educational activity is crucial for the improvement of dental school’s performance. The process of the evaluation needs a valid and reliable tool. This study aimed to produce and validate a questionnaire for the evaluation of dental school teachers by students.
Materials and Methods: A group of 15 teachers in the Shahid Beheshti dental school gave their opinions regarding the characteristics of an ideal teacher using nominal group technique. These characteristics together with characteristics gathered from similar studies made the base of a questionnaire which later underwent a validity and reliability assessment by means of the calculation of Content Validity Index (CVI), Content Validity Ratio (CVR), and Cronbach’s alpha coefficient.
Results: The preliminary questionnaire included 94 items in four categories naming: ethics, educational capability, practical capability, and managemet. After calculating CVR and CVI for each item, 23 items with CVR<0.33 and 20 items with CVI<0.79 have been excluded from the questionnaire leaving a questionnaire with 54 items. The overall reliability of this questionnaire using Chronbach’s alpha coefficient was 0.96.
Conclusion: Consulting an expert group that are familiar with different aspects of educational performance of faculty teachers, it was concluded that applying various methods for validity and reliability, and considering local culture values are useful for the preparation of the questionnaire for similar studies in Iran.

Abstract
Background and Aims: Despite advances in trauma management, treatment of the consequent infections has remained a major challenge. Antibiotic prophylaxis has been widely applied to reduce such infections. Although bacteria are present in most body parts, severe infections after treatment are less frequent in the head and neck of healthy individuals. The aim of the present study was to review the reasonable application of antibiotic prophylaxis in maxillofacial trauma.
Materials and Methods: In this review article, PubMed and Google Scholar databases were searched for studies on antibiotic prophylaxis in maxillofacial trauma published during 2000-2014.
Conclusion: Antibiotics were not prescribed for tears and small clean wounds in the face and mouth. However, prophylaxis was applied for extensive mouth injuries which involved the facial skin. In case of maxillofacial fractures, 24-hour administration of antibiotics sufficed for compound fractures of the mandible and other parts of the face. Antibiotics were not required in other types of fractures. Prophylaxis should be applied over short pre- or post-operative periods based on the severity and complexity of maxillofacial fractures and their relations with intra- and extraoral environments. Apparently, more detailed studies are warranted to further clarify the subject.

Abstract
Background and Aims: Trauma to primary and permanent teeth caused post-traumatic complications affecting the health of teeth and led to specific problems in treatment. As prognosis of trauma has closed correlation with immediate and correct management after occurrence of the incident and the health educators are the first people in contact with children in this places, their awareness of how to deal with these injuries plays an important role in prevention and treatment. This study aimed to evaluate the knowledge of health educators in confrontation with dental injuries in primary schools of Sanandaj in 2018.
Materials and Methods: In this cross-sectional study, all of fifty-nine health teachers in primary schools of Sanandaj were identified after referring to education centre. The questionnaires were provided to the school health teachers after referring to schools and after completing questionnaires, collected data were analyzed. In order to test the research hypotheses, Multiple regression, Non-parametric tests of spearman correlation coefficient, Mann-Whitney and kruskal-wallis were utilized using SPSS software version 20.
Results: The mean knowledge score of fifty-nine health educators was 14.02±3.41 and knowledge score of females was higher. There was no significant statistical correlation between knowledge score, age,
work experience and education level (P>0.05). In this study, the knowledge score of experienced teachers in confrontation with injured persons and health educators who attended related training courses, was higher than others but this difference was not statistically significant (P>0.05).
Conclusion: The results indicated inadequate knowledge regarding emergency management of dental trauma. Thus strategies to improve the teachers’ knowledge about dental trauma can positively influence their knowledge and attitudes toward emergency management of dental trauma.

Abstract
Background and Aims: Selecting the appropriate education evaluation method and the effects of this choice according to different fields of medical sciences, is one of the current priorities of medical education. Therefore, the aim of this study was to design a checklist for evaluating the practical skills of dental students and to get compared with the global ranking method.
Materials and Methods: A checklist was developed for the assessment of clinical skills of the practical pediatric course according to an action research method. 32 students were evaluated by the checklist method and 32 students were evaluated by the conventional global rating method (sampling was based on available sample). Faculty staff and students’ satisfaction regarding the two methods were reported by a 6-scaled measure and statistically analyzed by Wilcoxon Signed Ranks test. The students' scores by the two methods were subjected to paired t test for comparison.
Results: The students were more satisfied with the checklist method (P=0.003). The faculty staff considered a greater ability of the checklist method to differentiate between the students (P=0.03). However, in terms of ease of use and suitability, most faculty staff preferred the traditional method (P=0.02). In other cases, there were no significant differences in the views of students and faculty staff towards the two methods.
Conclusion: In the present study, both Checklist and global rating methods were valuable for evaluation, although due to the greater satisfaction of students and faculty staff with the developed checklist method, the possibility of identifying the weak points leading to decreased scores and better assessment of capabilities, this checklist can be used for evaluation instead.
