Using a biological indicator to detect potential sources of cross-contamination in the dental operatory

Article Abstract:

Viridans streptococci may be useful biological indicators of contamination of dental equipment and supplies with saliva from a previous patient. Viridans streptococci are bacteria that normally live in the human mouth. They can be easily identified when grown on blood agar and can be distinguished from other organisms. Surfaces of dental equipment and supplies can be wiped with a damp swab, and fluid from the swab can be cultured for viridans streptococci. The presence of the bacterium would indicate that the equipment and supplies have not been properly sterilized.

Article Abstract:

Disinfecting dental waterlines with hydrogen peroxide can substantially reduce bacterial contamination. Although no outbreaks of communicable disease have been linked to dental waterlines, the water does contain potentially serious bacteria, including Legionella, Pseudomonas, and Mycobacterium.
