Document Type and Number:
WIPO Patent Application WO/2018/042829
Kind Code:
A1
Abstract:
This toothbrush comprises: a main body, further comprising a head part which includes an erect bristle surface whereupon bristles are disposed in an upright state; a light emitting part which is mounted upon the main body and which irradiates light toward a tooth surface via a specific region among the erect bristle surface; and photoreceptor parts which are mounted upon the main body and which receive reflected light from the tooth surface via said specific region, said reflected light being produced by said irradiated light. The toothbrush further comprises a detection unit (S2, S3) which, on the basis of an output of the photoreceptor parts, simultaneously detects the presence or absence of the plaque or the tartar upon the tooth surface. The toothbrush further comprises an assessment unit (S5) which, when a state of the detection of presence of the plaque or the tartar which is performed by the detection unit has continued for a predetermined interval from the commencement of brushing with regard to the tooth surface, assesses that the tartar is present upon the tooth surface.
