Plaque Detecting Device and Toothbrush Incorporating Same |
abstract |
A plaque detecting device including a light emitting unit which irradiates light toward a tooth, and first and second light receiving units which receive radiated light from the tooth. The first light receiving unit extracts the spectral component of a first wavelength region containing fluorescent light specific to plaque and obtains a first output value corresponding to intensity of that spectral component. The second light receiving unit extracts the spectral component of a second wavelength region containing fluorescent light specific to enamel and obtains a second output value corresponding to the intensity of this spectral component. Determination of the relative magnitude of the ratio between the first output value and the second output value as compared to a first threshold value is performed. Determination of the relative magnitude of the difference between the first output value and the second output value as compared to a second threshold value is performed. |
