The purpose of this study was to investigate the amount of bacterial contamination of waiting room chairs in a private practice dental office. The Center for Disease Control (CDC) states that any medical clinic should include policies and procedures for routine cleaning and disinfection of environmental surfaces as part of the infection control plan. The CDC also encourages these types of clinics to use a checklist regarding prevention control so that the clinic can be assessed periodically to make sure that the clinic is reaching a minimum requirement for safe care. A study was conducted in two private practice clinics and three separate clinics at the University of Detroit Mercy School of Dentistry. 45 Swabs were taken of the three surfaces of the arms of three chairs in each of these clinics. The swabs were tested in a Ruhof ATP Complete machine and revealed that these surfaces were contaminated with bacteria. These results indicated that bacteria is contaminating waiting room chairs and creates a potential for cross-contamination
