ABSTRACT:
A measuring device for measuring the depth of a blind pocket formed around a tooth. A first embodiment of the measuring device has a measuring probe of optical material, such an optical fiber or rod, that has light-emitting notches or grooves near the probe tip, the notches being spaced to form a rule. The probe can be coupled to a light source, such as a penlight which can also be used as handle. The measuring probe is provided with an optical path to conduct light from the light source to the light-emitting ruler markings. A second embodiment of the measuring device has a measuring probe with a tapered tip formed by a staircase bundle of optical fibers covered by a transparent sheath. When light is introduced into a light source end of the staircase bundle of optical fibers, the opposite end in the probe's tapered tip is illuminated in a staircase pattern that can be used as rule.
