Disinfection Trends of Dental X-ray Machines in North American Dental Schools

Introduction: This study evaluates the trends in the disinfection of the dental X-ray machines in North American dental schools. The methods of disinfection were compared to the Centers for Disease Control (CDC) guidelines. Materials and Methods: A survey posed the question of whether plastic barrier wrap, bag, disinfecting wipes, or a combination were used for infection control of the tube head. Additional information was gathered from the dental schools’ infection policy guides and clinic manuals available online. Results: Of the forty-two Canadian and US dental schools surveyed, 24% used disinfectant wipes, 19% used bags, 19% used plastic surface barriers, and 38% used a combination. Conclusion: The majority of schools used a combination of the three methods, and all institutions abided by the CDC guidelines. As bags are more cumbersome to use with a rectangular collimator, wipes and barriers are arguably better methods to disinfect the X-ray tube head.
