Background: Proper and timely post-exposure prophylaxis (PEP) after needle stick exposure to high-risk body fluids significantly reduces occupational transmission. Objectives: This study was conducted with the aim of demonstrating the level of knowledge and practice amongst general dental practitioners in Hamadan city, Iran in ۲۰۱۳ - ۱۴, in terms of prevention after dealing with blood-borne pathogens. Materials and Methods: In this descriptive cross-sectional study, all general dental practitioners in Hamadan provided information on their preventative approach after dealing with blood-borne pathogens, via a pretested self-administered questionnaire in three parts. The first part consisted of demographic features, the second part (۱۵ questions) demonstrated knowledge level, and the last part (۵ questions) measured dentists’ practice in terms of prevention after dealing with blood-borne pathogens. Data from the ۸۲ questionnaires was analyzed using SPSS ۱۶ software, Mann-Whitney, and chi-square test (α = ۰.۰۵). Results: The mean score of knowledge was ۷.۹ ± ۲.۵۲۲ (from a possible total score of ۱۵). The lowest and highest scores were ۲ and ۱۴. ۶۰.۷% of the dentists had trained their staff; ۵۸.۸% of them accepted infected patients, and ۶۵.۹% had attended a PEP workshop. It was found that, of the demographic features, only gender had a significant correlation with level of knowledge (P = ۰.۰۰۰۱). Conclusions: This study revealed a low level of knowledge and practice regarding post-exposure prophylaxis, with the mean score of some respondents being below ۵۰%.
