Abstract

A dental handpiece having a gripping sleeve, a drive aggregate arranged in the handpiece for a dental treatment work tool retained in a head portion, and which includes its own built-in electrical light source. The light source, together with conduits for supply media, is arranged within an intermediate member which is exchangeably mounted between the gripping sleeve and the end member of a supply hose for the media for the handpiece. The light from the light source, with the aid of strand-like light conductors arranged interiorly of the handpiece, is conducted to the region of the handpiece head portion and exits therefrom the gripping sleeve directed towards the tooth treatment worktool, and in which the light source can be switched on and off through the intermediary of a compressed air-driven pneumatic switch device.
