The study evaluated the perception of dental students who have or have not experienced accidents with sharp objects regarding the institutional strategy for controlling hepatitis B vaccination. A retrospective observational case-control study was conducted involving 139 participants, of whom 36 had experienced accidents with sharp objects in a dental clinic (case group – CG) and 103 had not (control group – CGt). Information about accidents was obtained from institutional notification forms. Participants completed an online questionnaire assessing their perceptions of the institutional policies on mandatory vaccination and the occupational risks faced by dental professionals. A total of 204 students were enrolled across six classes in which cases were reported (36 cases, 17.6%). The most common cause of accidents was the anesthesia needle, and 72.2% of accidents occurred with students in the fifth and sixth semesters of the undergraduate program (third year). CGs assigned higher scores to the importance of mandatory vaccination and reported lower confidence levels regarding the risk of contracting hepatitis B and HIV in the event of a biological accident. It was concluded that one in six students reported sharp objects-related accidents, the majority of which could have been prevented by adherence to biosafety protocols. For most students, the experience of such an accident led to a deeper understanding of the biological risks involved.
