Cross infection in the high-touch areas of dental radiology clinics.
Disinfection and sterilization have received considerable attention due to the spread of AIDS and HIV. Several infections hazards to the patient and personnel of dental surgery have been identified from blood, saliva and water of dental unit. The high touch areas of dental x-ray equipment is a potential source of infection. The present study was undertaken to determine the extent of cross-infection present in the dental radiology clinics with and without the use of surface disinfectants. Swabs taken from high touch areas of the x-ray equipment in 15 different sessions with in one month were cultured in three different media. The study revealed, almost all high touch areas in dental radiology clinic had bacterial contamination in the absence of surface disinfection. "Webcol" and "Superficid" disinfectants showed minimum or no contamination. To remove risk of cross-infection, disinfection of high-touch areas of dental x-ray equipment is mandatory.
