Abstract
A dental prophylaxis tool handpiece includes a motor section having a first connector; a sleeve section having a second connector with a first end extending over a portion of the motor section and engaging a prophylaxis tool at a second end; the first and second connector configured for engagement with each other and configured to limit relative axial movement of the sleeve section relative to the motor section while allowing for free rotational movement of the sleeve section relative to the motor section; and upon engagement of the sleeve section with the motor section, a portion of the motor portion is covered to substantially isolate the portion of the motor section from contaminants. Other embodiments incorporate a positive air pressure feature and/or an ozone generator. Associated methods of preventing contamination of at least a distal portion of a motor section of a prophylaxis tool handpiece are also described.
