Survival of herpes simplex virus and other selected microorganisms on patient charts: potential source of infection.
This study indicated that when inoculated onto dental charts, both viruses and bacteria were capable of survival allowing the potential for transmission of infection within the dental office. The conscientious dental practitioner can take steps to reduce this possible mode of infection by removing contaminated surgical gloves or washing hands before handling the chart. An additional method of reducing this potential would be to wipe the chart with an antiseptic solution. Although this study has shown that there is a potential for the spread of infection with the organisms tested, the actual extent of dental chart contamination and resultant illnesses contracted are the basis for further study. Additional studies are needed to follow the pattern of chart distribution from person to person within the dental office, determine the types and quantities of pathogens present in the mouth that would contaminate the charts, and sample the charts under actual clinical conditions to determine the types and viability of the organisms present.
