The high occupational risk due to perforating injuries and the frequent contact with organic fluids of dentistry students are a reality that has been successfully faced by São Leopoldo Mandic. The prior study analyzed between the years 2006 and 2013, 100% of the students were vaccinated and 91.3% were seroconverted based on the results of anti-HBs. The strategy consists in demanding vaccination proof and conduct seroconversion confirmation tests, in some cases restricting the access to the clinic. In this context, through a retrospective case-control study, the current study is going to aim to evaluate the students' perception of the institution's demands regarding the experience or not of perforating injuries. Students with notifications of perforating injuries from the biosecurity sector will form the case group, and non-injured students from the same period will form the control group, following a proportion of 1:3. It's expected that the results may update the information about the efficiency of the Biosafety strategy adopted by the HEI, completing the amount of vaccination and seroconversion data in the period from 2014 to 2017, besides allowing to understand, from the perspective of the student, how is the perception of this strategy.
