The invention provides a dental caries diagnostic instrument and a periodontal disease diagnostic instrument capable of quantitatively diagnosing the severity of dental caries and periodontal disease; and a diagnostic method therefor. The invention also provides a diagnostic system comprising the diagnostic instruments. The optical dental caries diagnostic instrument 1 is provided with a light source 20, an indenter 30 which is contacted with a tooth, and a light receiving element 40. The indenter 30 is light transmissive and has a tapered shape. The light source 20 emits light to the indenter 30. The light receiving element 40 receives light from the tip of the indenter 30.
Description
technical field [0001] The present invention relates to an optical caries diagnostic instrument capable of diagnosing dental caries by holding a small device with one hand, an optical caries diagnostic method, a dental caries diagnostic system including the optical caries diagnostic instrument and the optical caries diagnostic method, and a periodontal disease diagnosis system. Optical periodontal disease diagnostic instrument. Background technique [0002] In order to maintain the health of teeth and gums, and thus maintain the health of the whole body, prevention and appropriate treatment of dental caries and periodontal disease are social needs. Especially for the elderly, it is known that the number of remaining teeth is highly correlated with the onset of dementia, and maintaining the health of the teeth is considered to be effective in preventing dementia. If the incidence of dementia can be reduced through preventive dental care, a significant reduction in care costs...
