title: Infection control update: beware of the ragwheel.
abstract: Previously, concern about infection control in dentistry emphasized the handpiece, operator safety, barrier technique, and patient protection in the dental operatory. As current knowledge of infection control increases an expanded understanding of other sources of disease transmission is indicated. Often overlooked is the dental laboratory of which particular interest focuses on the lathes used in preparing prosthetic appliances, castings, orthodontic appliances, and surgical stents. Specifically, the potential threat of the ragwheel to the patient and operator is significant. Ragwheels and pumice samples were collected and cultured, the results of which mandate the need for infection control guidelines for the dental laboratory.
