Abstract
Statement of Problem: Hepatitis C is a relatively common infection which can be transmitted through accidental inoculation consequently dentists are highly at the risk of exposure to this virus.
Purpose: The aim of this study was to determine prevalence of Hepatitis C among the dentists of Yazd and to evaluate their knowledge about the existing ways for the transmission and prevention of this infection.
Materials and Methods: In this descriptive- analytic study which was performed periodically (2002), the sera of all dentists practicing in Yazd were tested (104 samples) in the laboratory of Yazd blood transfusion organization initially by 1st generation of Elisa for Anti HCV followed by Riba on positive samples to confirm the results. Meanwhile a questionnaire assessing their knowledge about hepatitis was completed the by the dentists. Data were analyzed by ANOVA and t test.
Results: None of the one hundred and four samples of sera were positive for Anti HCV. Mean score of their knowledge was 14.80 (of 20). The knowledge of 92.1% of them was at moderate to high level. No significant difference was observed between Yazd's dentists knowledge about hepatitis C in different age, gender and length of professional experience groups.
Conclusion: According to this study, the absence of HCV among the dentists of Yazd is mainly attributed to the low prevalence of HCV infection among general population, though it can also be an indicative of the knowledge and excellent performance of the dentists to prevent the transmission of infection through blood and saliva.

Abstract
Background and Aims: Fissure sealant therapy is a national program in elementary schools in Iran. Therefore, evaluation of the parents' knowledge and attitude is necessary to improve the program.
Materials and Methods: In this cross-sectional and descriptive-analytic study, Iranian students were chosen in a randomized cluster manner. The questionnaires were filled-out by students' parents to evaluate their general information, knowledge, and attitude. Moreover, students were examined for having any fissure-sealed teeth. Data were collected and analyzed by multiple logistic regression tests.
Results: 414 boy students and their parents were participated in this study. 57.6% of parents knew that fissure sealant prevents the caries and 44.5% believed that fissure sealant is important to prevent caries. However, only 8.9% of children had fissure sealant. Parents' knowledge was significantly related to the source of oral health information and oral health education. Regular dental visits and high level education was effective in increasing the knowledge about sealant therapy. There was a significant relation between parents' attitude toward fissure sealant and level of education, oral health education and numbers and times of dental visit (P<0.001). There were a significant relation between tooth sealing and parents' oral health information.
Conclusion: Regular dental visits and oral health education have positive role in parent's knowledge and attitude and practice. So parents must be encouraged to have regular dental visit and dentists must be emphasized to give them necessary education. School is the best place for giving proper information to parents.

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.
