Evaluating chemical inactivation of viral agents in handpiece splatter.
The water spray used with a modern high-speed dental drill is a significant vehicle for dispersion of infectious agents into the environment, putting patients and the dental staff at risk of infection. This study examines whether disinfectants added to the handpiece water supply could inactivate viral contaminants in splatter. Results supporting use of ethanol or sodium hypochlorite are presented.
