Abstract

Purpose: To evaluate the knowledge of dental students about disinfection of irreversible hydrocolloid impression. Methods: The sample consisted of 80 dental students of the sixth and eight terms of the Dental Course at Centro Universitário da Fundação Educacional de Barretos, Barretos, SP. Data were collected using a questionnaire with eight multiple choice questions about disinfection of irreversible hydrocolloid impressions and biosafety. Data were analyzed in a descriptive and qualitative format. Results: Most subjects (90%) stated that they were aware of the risks of irreversible hydrocolloid impressions to spread infectious diseases. However, only 66% answered that they had learned a disinfection method for impressions. Many students (41%) did not know which solution should be indicated for impression disinfection and only 70% used to wash the impression in running water before chemical disinfection. Conclusion: The dental students are aware of the potential contamination risks by irreversible hydrocolloid impressions, but their acquired knowledge and practices on technical procedures to properly disinfect impressions and control cross-infection are insufficient. Key words: Biosafety; disinfection; dental impression
