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.
