ORAL CAVITY CARE DEVICE

PROBLEM TO BE SOLVED: To store a care region of an oral cavity and a plaque amount detected correspondingly to the care region.SOLUTION: This oral cavity care device includes: a care member for caring the oral cavity; an attitude detection part 510 for detecting the attitude of the care member; a region estimation part 520 for estimating the care region of the oral cavity based on the detected attitude; a light source emitting light of a prescribed wavelength on which plaque reacts; a photoelectric conversion part receiving light and converting it into an electric signal; an imaging part 530 making the light source emit the light to the care region, and acquiring image data based on the electric signal obtained by converting reflected light from the care region by the photoelectric conversion part; a plaque detection part 540 for detecting the plaque amount of the care region based on the image data acquired by the imaging part; and a storage part 55 for associating the care region estimated by the region estimation part and the plaque amount detected by the plaque detection part about the care region, and storing them in a memory.
