Abstract
A dental tartar detection system (10), especially for detection of subgingival tartar (S), comprises a probe (12) adapted to be displaced along a tooth (T) an illumination system (14) for illuminating with an incident light a region on the tooth (T), a detection system (16) for collecting the light reflected thereat, and an analysis system (34) for providing a signal to an operator of the probe (12) when measurements on the reflected light in one or more predetermined range of wavelengths fall within any predetermined range of values that are characteristic of tartar (S). Typically, the detection of tartar (S) is achieved on the basis of the possible colors that tartar (S) can have such that the aforementioned one or more predetermined range of values cover wavelengths associated with colors of tartar (S).
