摘要： It is intended to provide a dental plaque detection system and a dental plaque detection method whereby dental plaque can be detected at a high accuracy while relieving the staining in parts (interdental space, gingiva, etc.) other than dental plaque. This dental plaque detection system comprises a dental plaque-staining agent containing at least one member selected from among a yellow pigment originating in red koji mold, a turmeric extract and curcumin and a light-emission unit (10) emitting light of from 250 to 500 nm in wavelength toward a subject (40) in the oral cavity having the dental plaque-staining agent attached thereto. The dental plaque detection method comprises attaching the dental plaque-staining agent having the composition as described above to a subject in the oral cavity and then irradiating the subject with light of from 250 to 500 nm in wavelength.

摘要： A dental-plaque detection system and dental-plaque detection method which are excellent in the detection accuracy of dental plaques and also capable of improving the situation to stain sites other than dental plaques (such as interdental parts and gums) are provided. The dental-plaque detection system includes a dental-plaque staining agent, which contains at least one selected from yellow pigment of beni-koji, turmeric extracts, and curcumin; and a light-emitting apparatus, which outputs light having a wavelength within a range of 250 to 500 nm to an object in the oral cavity where the dental-plaque staining agent is attached. The dental-plaque detection method includes attaching a dental-plaque staining agent, which contains at least one selected from yellow pigment of beni-koji, turmeric extracts, and curcumin onto an object in the oral cavity; and thereafter irradiating light having a wavelength within a range of 250 to 500 mn onto the object.
