ABSTRACT:
Described are dental implements useful for inspecting tooth surfaces for abnormalities such as caries or plaque. Preferred implements of the invention include light-emitting diodes mounted on an implement body having a mirror for insertion into a user's mouth. Such implements also have on-board batteries mounted in chambers in the implement handle, and a switch for energizing and de-energizing the LED with the battery. Also described are methods for examining tooth surfaces for abnormal conditions indicative of plaque involving illuminating surfaces with radiation at a wavelength in the range of 390-450 nm wherein the radiation is effective to cause detectable fluorescence emissions from bacterial metabolites known to be associated with plaque-containing surfaces, and detecting the emissions.
