Statement of problem: As HIV/AIDS transmits through direct contact and via blood (possibly also saliva), the risk of cross-infection in a dental practice has become important. Dentists play an important role in detecting and treating oral manifestations of HIV. Purpose: The aim of this study was to evaluate knowledge and attitudes among general dentists working in Tehran towards HIV/AIDS. Materials and Methods: In a cross – sectional descriptive study, knowledge and attitude among ۳۷۰ dentists towards HIV/AIDS were evaluated by a questionnaire consisting of ۲۹ questions. Results: Three hundred and seventy dentists, consisting of ۲۶۲ males (۷۰.۸%) and ۱۰۸ females (۲۹.۲%), participated in this study. The mean age was ۳۸.۶ (range ۲۵-۵۷ years) .The mean years of work experiences after graduating was ۱۲.۹±۸.۳ years (range ۰-۲۹ years). In this study, the total maximum score was ۷۲ (۴ scores for each correct answer). Conclusion: In general, level of dentists’ knowledge about HIV/AIDS was low. An educational program about AIDS is highly recommended.
