Gingival detection using a photodetector in a dental hygiene detector

摘要

The detection device 1000 detects the material 116 that may be present on the surfaces 30, 31 based on the measurement of the stream probe signal that correlates with the substance 116 that at least partially obstructs the passage of the fluid 30, 35 through the stream probe 500. Including a distal optical gingival detector transmitter 620 and a distal optical gingival detector receiver 720 that respectively transmit and receive optical signals controlled by the controller 2251 and stream to invalidate false positive signals Whether the opening 526 of the distal tip 522 of the probe 500 is in contact with the substance 116 that at least partially obstructs the passage of the fluids 30, 35 through the opening 526 and is not in contact with the subject of the detection device 1000 or the user's gingiva. Allows controller 2251 to determine.
