[Multicentric survey on hygienic aspects in private dental practice].

The aim of this research was to evaluate the knowledge of cross-infection hazards in private dental practices, and their control procedures. The survey, carried out by questionnaire in 11 Italian cities, showed that dental personnel do not completely follow the main procedures for infection control. The interviewed subjects usually wear gloves (95.5%), masks (90.1%) and glasses (91.2%), less frequently caps (23.9%) and coats (54.9%). They use steam sterilizers (92.9%) and periodically check the effectiveness (80.6%). Regarding individuals protection, 20.5% is not vaccinated against HBV and only 55.2% of those previously vaccinated has checked their immunity. Moreover, the majority of subjects underestimate the infection hazards especially for air-transmitted diseases.
