RESUMO
To achieve adequate infection control in the dental practice, dental students should be fully aware and prepared to adopt necessary procedures. But most studies of students' infection control behaviors rely on self-reported data. This study verified, through direct observation, how senior dental students performed basic infection control procedures and assessed how close to reality the reported behavior is to the observed behavior. Eight students were observed in three clinics: pediatric dentistry, minor oral surgery, and primary care promotion. The students were not aware of who was being observed or why. Later all twenty students comprising that clinical subgroup answered a questionnaire. Seventy-two patient-student contacts were observed. Students considered basic infection control procedures as relevant. The reported intention of adoption of these procedures after graduation dropped in relation to their reported relevance. Although the observed behavior in the three clinics was considered satisfactory, when compared to the reported behavior, it was found that the intention was more positive than the behavior itself. Even though the students were conscious about the importance of cross-infection control in the dental practice, the reported intention of future use and mainly the observed behavior should be improved.
