Materials and Methods: This cross-sectional study was carried out on ۱۰۰ dentists in Zahedan in ۲۰۱۳. A reliable and valid questionnaire on knowledge, attitude and performance of the dentists toward the infectious diseases of HIV, hepatitis B and C was distributed to all dentists who worked in Zahedan. Data were analyzed using one-way analysis of variance (ANOVA), independent sample t-test and Spearman rank correlation coefficient. Results: The mean score of the knowledge, attitude and practice of the dentists were ۵۱.۴۵ ± ۳.۱۶ out of ۶۳, ۲۰.۲۲ ± ۳.۷۴ out of ۳۹ and ۶۴.۴۱ ± ۴.۴۹ out of ۷۲, respectively.

The relationship between demographic variables and the level of knowledge, attitude, and practice of dentists was not statistically significant. Conclusions: Although the dentists had a proper knowledge in the field of transmission of HIV, HBV, and HCV infections, fear and concern of being infected make them to refuse these patients.
