Abstract
A dental handpiece having a mechanism for mounting a bur in one end thereof. A fiber optic system is mounted within the handpiece, and is adapted to direct light adjacent the bur when it is rotating to aid a dentist in using the handpiece. The fiber optic system includes a bulb mounted within the handpiece, which bulb is secured in a housing formed from a heat-resistant plastic. Air used for driving the handpiece is also used to cool the heat generated by the light. A pneumatic switch is provided for automatically turning on the light when the handpiece is used and for automatically turning off the light when use of the handpiece is terminated.
