Abstract
Automatic apparatus for cleaning dental handpieces and turbines is in the form of a housing having a compartment with hinged door. Standard motor noses project down from the top of the compartment to receive handpieces or turbines to be cleaned. Cleaning fluids, namely water, a disinfectant and oil are supplied sequentially to the motor noses while internal shafts of the motor noses are rotated by a set of pinions to drive the handpieces or turbines while the fluids are passed through them. The hinged door has an inflatable tube seal.
