Knowledge and practices about sterilization and disinfection.

Abstract

The aim of the present study was to evaluate the knowledge and practices employed for infection control in dental laboratories. A preformed questionnaire comprised of 16 questions related to infection control measures was prepared. This questionnaire based survey was then conducted among dental technicians of 60 dental colleges in East India. Data were then recorded and analyzed. Majority of impressions/prosthesis were carried in plastic bags (93.8%) by laboratory attendants to the laboratory. The responses revealed that majority of impressions were received after wearing gloves (54.6%) from dental attendant. Majority of dental technicians (78.1%) admitted in their responses that they are not aware of infection control measures taken in dental laboratory. Only 32.8% technicians were found to practice disinfection procedure after receiving impression/prosthesis in laboratory from dental operatory. Among protective wears, 70.3%, 95.3%, 32.8%, and 92.2% technicians were found to use gloves, Apron, eye shield, and face mask, respectively. Among all respondents, 59.3% were found to be vaccinated for hepatitis B vaccine. There is lack of knowledge and motivation among dental technician to practice infection control measures in dental laboratories of dental institutes in North India.
