Abstract
Background and Aims: Evaluation of the training is a principle for successful education. This study evaluated the effect of the theoretical course of community oral health on knowledge, attitude and self-reported practice of preventive dentistry in dental students at Tehran University of Medical Sciences and assessed the students' satisfaction from the course.
Materials and Methods: The intervention group comprised the forth-year students of Tehran University of Medical Sciences, Dental School and the controls were the forth year students of Shahid Beheshti Medical University. The questionnaire included questions on backgrounds, knowledge, attitude and practice of students towards preventive dentistry, and students' satisfaction from the course. The intervention was 17 weekly sessions (hours) of the community oral health course. The sum of scores for questions on backgrounds, knowledge, attitude and practice were calculated and changes were analyzed by General Linear Model.
Results: The mean baseline knowledge score in the intervention group was 16.9 (SD=4.0) and for the control group 16.3 (SD=3.5). Corresponding figures were 23.7 (SD=3.4) and 17 (SD=3.3) after intervention. General linear model showed the intervention to be successful in increasing the students' knowledge scores on preventive dentistry (P<0.0001). Most students (92%) were satisfied with learning several new items during the course.
Conclusion: The students' knowledge was successfully increased by passing the theoretical course of community oral health delivered by teacher-centered method of lecture. Student-centered methods may help in changing the students' attitude and practice of preventive dentistry.

Abstract
Background and Aims: The aim of the present study was to investigate self-perceived need to learn practice management and self reported knowledge in this regard among dentists.
Materials and Methods: A group of five academic staff members of Community Oral Health Department (Tehran Dental School) and four dentists formed an expert panel to develop the content of the course. This group developed a list of topics related to principles of successful dental practice. To investigate the necessity of educating the topics and self-assessed knowledge of the topics, a questionnaire was designed and administered to 55 volunteer dentists. Forty six dentists completed the questionnaire. T-test and Chi-square test were used for statistical analyses.
Results: Totally more than two-third of the dentists believed that a huge need exists for education of all the topics. The corresponded figure for such topics as ergonomics and medical emergencies was about 90%. About 80% of the dentists felt that they had a vast knowledge of safety and infection control. On the other hand, 54.3% of them reported weak knowledge regarding professional rules and regulations. Self-reported educational need and knowledge of the dentists did not show significant association with their age, gender, and work experience
(P>0.05).
Conclusion: The dentists believed in the necessity of educating such topics and evaluated their knowledge as deficient in these areas. This shows the necessity of developing courses on these topics.

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: Debonding at the cement-dentine interface is the main reason of failure in restoration of endodentically treated teeth with fiber posts. The aim of this study was to compare the effect of Starfill 2B danville and Panavia F2 kuraray cements on the retention of fiber posts to root canal dentin.
Materials and Methods: Twenty extracted mandibular premolar teeth which had single root canal were endodentically treated and decoronated. Teeth were randomly divided into 2 groups, (n=40). Fiber posts were cemented using 2 dual cure resin cements. Group A was cemented with Starfill 2B Danville and group B was cemented with Panavia F2 Kuraray. Each root was mounted in acrylic resin and then sliced in 2 parts. The retention strength of each specimen was determined using push-out test using a universal testing machine. Data was analyzed using T-test.
Results: The retentive strength for groups A and B were 48.16±12.11 and 61.44±9.16 MPa, respectively. There was significant difference in the retentive strength between group A and B (P<0.05).
Conclusion: It seems that type of cement had effect on the retention of fiber posts. Panavia F2 Kuraray resin cement significantly provided higher retention than that of Starfill 2B Danville cement.

Abstract
Background and Aims: One of the most effective methods in reducing the prevalence of caries is oral health education. The aim of this study was to evaluate of two educational interventions regarding prevention of early childhood caries on self-reported practice of parents of 2-5-year-old children receiving dental treatment under general anesthesia.
Materials and Methods: In this interventional study, the effects of two different educational interventions
(pamphlet and pamphlet along with reminder) on self-reported practice of parents of 2-5-years-old children receiving dental treatment under general anesthesia was assessed. Thirty seven couples of children and mothers in two groups were randomly selected. Before and three months after interventions, a standard questionnaire regarding self-reported practice of mothers on prevention of early childhood caries was completed by respondents. Moreover, oral examination including Simplified oral hygiene index (S-OHI), dmft, and white spot lesions were rerecorded at the beginning and three months after interventions. At this time in one of the groups reminder phone calls were made every month. Finally, the answers were scored and data were statistically analyzed to be compared in pre- and post-test.
Results: Comparing each of the groups before and after interventions showed that in both groups there were significant differences in mothers’ perception of perceived ability to make child brush his teeth twice a day (P=0.001), and child’s tooth brushing frequency more than once a day (P=0.03). S-OHI had no significant difference after the intervention between two groups. But each group had a significant decrease three months after intervention (P=0.003). Also the mean number of white spots showed a significant decrease before and after intervention in each groups. Regarding mothers’ self-reported practice no significant difference was observed between two groups (P>0.05).
Conclusion: Using pamphlets along with or without reminder as educational measures had similar enhancing effects on the mothers’ self-reported practice on oral health of children within three months.

Abstract
Background and Aims: Trauma to the permanent and deciduous incisors is an undesirable common event in childhood. Proper immediate management of injured teeth is depended on the knowledge of unprofessional people, including teachers, who are usually present at the scene prior to dental treatment. The aim of this study was to assess the knowledge and self-reported practice of primary school teachers on the emergency management of traumatic dental injuries (TDIs) in Arak.
Materials and Methods: In this cross-sectional study, 624 primary school teachers were enrolled in census in Arak. An anonymous questionnaire containing demographic data, the history of previous exposure to traumatic dental injuries, teachers’ knowledge regarding emergency management of TDIs and their practice towards TDIs was used. Questionnaires were distributed among all participants and then were collected on the same day. Descriptive statistics and linear regression were performed to analyze the data.
Results: A total of 292 completed questionnaires (response rate 46.8%) were collected. The mean score of knowledge was 2.65±1.69 out of 10. The mean score of self-reported practice was 3.46±2.04 out of 8. Regarding the demographic variables, knowledge had a significant relationship with the education (P<0.001). No significant relationships were observed between the self-reported practice and demographic variables. The correlation coefficients between the knowledge scores and the practice scores of teachers was 0.2.
Conclusion: This study revealed that insufficient knowledge exists among primary school teachers on emergency management of TDIs. Furthermore, a high percentage of respondents enjoy a significant deficiency regarding favorable practice encountering TDIs.

Abstract
Background and Aims: Disabled individuals are involved with several oral health problems. The aim of this study was to assess the knowledge and perspective of dentists towards oral health promotion in disabled individuals.
Materials and Methods: Dentists participating in the fifty-fourth International Congress of Iranian Dental Association in 1392 in Tehran were invited. A valid and reliable questionnaire including the information about age, gender, city of practice, the working experience with the disabled was distributed. There were also 13 questions on knowledge and one question about the importance of training in the field of “oral health promotion of the disabled” in this questionnaire. The data were analyzed by linear regression model by SPSS 18 software.
Results: 117 questionnaires were collected and evaluated. The mean age was 35.5 (10.1) years. Among the participants, 53.8% were male and 46.2% were female. Average score of knowledge was 6.5 of the maximum attainable 13. Among the dentists, 60% believed that receiving education on oral health promotion for the disabled is important. Liner regression model which evaluated the effect of confounding factors showed that aging led to reduction in dentists' knowledge of oral health of the disabled. Furthermore, working experience with the disabled led to the increase in knowledge. Dentists who had previously treated a disable individual were more interested in receiving related training.
Conclusion: Knowledge of dentists in the field of oral health promotion of the disabled is not desirable while most dentists recognize the need for training. This issue emphasizes on the need for a broader educational effort.

Abstract
Background and Aims: Dental anxiety and fear can act as a barrier to seek dental care leading to insufficient oral health in people. The aim of this study was to determine the relations between dental fear and anxiety with dental caries status (DMFT) and clinical consequences of untreated dental caries (PUFA) among the adult patients referred to the faculty dental clinic of Tehran University of Medical Sciences.
Materials and Methods: In this cross-sectional study in 2019, the patients above 18 years old were assessed. Two standard questionnaires, Dental Fear Scale (DFS) and Modified Dental Anxiety Scale (MDAS), were used to assess the scores of dental fear, and dental anxiety, respectively. The demographic data of the patients were recorded. Dental caries status and clinical consequences of untreated dental caries, using DMFT and PUFA, respectively, were measured. Pearson correlation coefficients and multiple linear regression model (Backward method) were used for statistical analysis.
Results: Totally, 283 patients with the mean age of 38.6±11.8 years old participated. The mean scores of MDAS, and DFS were 12.04±4.49, and 41.33±16.87, respectively. Educational level (P=0.03, β=-0.14) and marital status (P=0.01, β=0.17) had significant relationships with MDAS scores. Moreover, a significant relationship was found between marital status and DFS scores (P<0.001, β=0.25). Significant correlations were found between dental anxiety level and D (P<0.001, r=0.36) and M components (P=0.02, r=0.14) of DMFT index. Moreover, there was a significant correlation between dental anxiety and U components of PUFA index (P=0.045, r=-0.12). Furthermore, the correlations between dental fear and D and M component of DMFT were significant (P<0.001, r=0.36; P<0.001, r=0.23; respectively).
Conclusion: Dental anxiety and dental fear were infrequent in the studied population; however, significant relationships were found between dental anxiety and dental fear with dental caries indices. Therefore, it was concluded that the more MDAS and DFS scores, the worse dental caries status.

Abstract
Background and Aims: The increase in life expectancy and decrease in birth rate enhances the elderly population in different societies and consequently, the demand from the health system for providing the treatment needs has been elevated. It has been proposed that dentists must improve their attitude, knowledge, and practice to meet these needs. The present study aimed to assess the knowledge, attitude, and practice of general dentists regarding geriatric oral health.
Materials and Methods: In this descriptive-analytic cross-sectional study, 150 general dentists participating in the annual congress of the Iranian Dental Association in 2018 were selected and completed a valid and reliable self-administered questionnaire including 5 parts about knowledge, attitude and practice regarding old age and oral health of elders. SPSS23 and multiple regression were used for data analysis.
Results: The mean age of dentists was 34.3 (SD: 9.1) and 92 (61.3%) of participants were women. The mean knowledge score about the old age was 16.67 (of maximum: 26, SD: 4.31) and the mean knowledge on the geriatric oral health was 11.01 (of maximum: 18, SD: 2.81). The mean general attitude about elderly was 19.1 (of maximum: 30, SD: 4.26), the mean attitude on geriatric oral health was 13.09 (of maximum: 20, SD: 2.65), and the mean practice about geriatric oral health was 6.5 (of maximum: 10, SD:2.96). Age was significantly associated with knowledge regarding the elderly (P<0.034); i.e. with increase in age lower scores in knowledge were gained.
Conclusion: General dentists participating in the congress of the Iranian Dental Association demonstrated a medium level of knowledge, attitude, and practice regarding the oral health of elders. Proper educational programs should be planned in dental schools to improve dental student's knowledge, attitude and practice about geriatric oral health.

Abstract
Background and Aims: Considering the problems associated with occupational stress and burnout caused by this stress, this study aimed to determine the academic burnout, dental environment stress, and their association among dental students in Isfahan.
Materials and Methods: This analytical cross-sectional study was conducted in 2020, applying a convenient sampling method. Data collected from undergraduate dental students from Isfahan University of Medical Sciences and Azad University of Isfahan using the validated Persian version of BCSQ-12-SS (Burnout Clinical Subtype Questionnaire) including 12 questions and DES (Dental Environment Stress) including 32 questions. Volunteer students filled in the online questionnaires using social media including WhatsApp and Telegram. Data were analyzed using SPSS26, U Mann-Whitney test, Kruskal-Wallis test, Spearman correlation coefficient, and a linear regression model (level of significance P<0.05).
Results: Among 300 participants (response rate=64%), the mean age was 24.25±2.72, and 54.7% were women. The mean score of academic burnout was 2.61±0.66 of the maximum score of 5. Overload was the most effective dimension of academic burnout. The mean score of DES was 2.80±0.51 of the maximum score of 4. Clinical education was the most effective dimension of DES. A direct correlation was observed between the dental environment stress and academic burnout (P<0.001; r=0.33).
Conclusion: The academic burnout among dental students in Isfahan was moderate and dental environment stress was high. Considering the direct association between the stress and burnout, more efforts should be made to reduce dental environment stress especially in the field of clinical education.
