Publication number: 20230301751Abstract: A distinguishing device for dental plaque and dental calculus includes a light-emitting diode, an image sensing unit, and a processor. The light-emitting diode movies in a first direction and is separated from teeth in an oral cavity by a predetermined distance in a second direction. The second direction is perpendicular to the first direction. The light-emitting diode generates a blue light to illuminate the teeth, so that dental plaque on the teeth generates a first autofluorescence and dental calculus on the teeth generates a second autofluorescence. The image sensing unit is configured to sense the first autofluorescence and the second autofluorescence. The processor is coupled to the image sensing unit to distinguish a dental plaque area from a dental calculus area on the teeth according to the first autofluorescence and the second autofluorescence.Type: ApplicationFiled: August 4, 2022Publication date: September 28, 2023Inventors: Kai-Ju CHENG, Yu-Hsun CHEN, Hao-Ping LEE, Tong-Ming HSU, Chin-Yuan TING, Shao-Ang CHEN, Kuan-Chung CHEN, Hsin-Lun HSIEH
