Abstract
A dental handpiece structure has a head and a handle. A mounting passage is formed through the head. A positioning recess is formed in a handle end and connected to the mounting passage. A curved narrow tip is mounted to a tip end of the head. The mounting passage extends toward the narrow tip. A water outlet is formed in a proximal end of the narrow tip and is adjacent to the mounting passage. A light guiding strip is disposed in the mounting passage. The handle has a light source corresponding in position to the light guiding strip. As a result, light emitted by the light source is concentrated on the narrow tip, thereby improving visibility.
