Survey of the knowledge and practice of infection control among dental practitioners

A survey on various aspects of infection control (overall knowledge/problem recognition, formal polices/reducing risk, and willingness to obtain additional education) was conducted among dental professionals and dental students. The survey was administered by a questionnaire at the offices of dental practitioners in Uberlândia and among dentistry students at the Federal University of Uberlândia. The two groups (professional dentists and students) differed significantly (P<0.0001) regarding recognition and reduction of the problem, but they were similarly willing to improve their knowledge of infection control. Dentists scored significantly higher than dental students on questions of recognition and reduction. A high proportion of students reported a lack of concern regarding routine handwashing before and after patient care (28.9% gave wrong answers). Of the dentists, only 8.8% reported a lack of knowledge about this matter. A higher proportion (P<0.0001) of dentists reported glove use and other basic barrier precautions (97.1% versus 51.9% among the students). However, the proportion of dentists who reported that they were aware of HBV vaccination was lower than among the students (81.5% versus 92.0%, p=0.0037). Additional education is required to promote a more realistic perception of the risks for HIV, HBV, and HCV transmission in dental offices and among dental students, and the use of all recommended infection control practices.
