Abstract
Background and aims. Blood-borne infections such as hepatitis B, hepatitis C and HIV might be
transmitted from one individual to another during dental procedures. Therefore, sterilization and personal
protection procedures are of utmost significance in dental offices. The importance of awareness of crossinfection
and antiseptic principles lies in the fact that in most cases it is not possible to identify patients with
hepatitis or AIDS. The aim of the present study was to evaluate awareness of infection control procedures
among dental practitioners in Tabriz.
Materials and methods. In this descriptive study, 150 dental practitioners working in clinics and private
offices of Tabriz were randomly selected. Data was collected by means of a self-administered questionnaire,
which included respondents’ personal profile and questions on infection control and sterilization methods.
Results. There were no statistically significant differences in the level of knowledge between male and female
dental practitioners regarding infection control; however, there was a decline in awareness as age increased.
Conclusion. The results of the present study suggest that in some cases dental practitioners neglect the
principles for personal protection and cross-infection control. Therefore, our society is subject to widespread
infection in dental offices and clinics. This potential risk necessitates careful monitoring along with government
support of treatment procedures, the inclusion of infection control costs into treatment expenses and an
emphasis on continuing education about infection control procedures through seminars and congresses.
