Problems solved by technology

This method uses external reagents to smear, and the indicator remains in the mouth, which is not easy to clean. The method of judging the plaque distribution based on visual observation is subjective, and quantitative non-destructive testing cannot be realized.

Description

technical field [0001] The invention belongs to the technical field of oral health monitoring, and relates to a dental plaque detection device, in particular to a device for detecting the content and distribution of oral dental plaque. Background technique [0002] Dental plaque is a bacterial film based on a sticky matrix that adheres to the tooth surface. The toxins and other harmful substances produced by the bacteria in the plaque directly stimulate the gums (commonly known as the gums) and inflame the roots of the teeth. Dental plaque is replaced by a new generation, decomposing sugar to produce acidifying substances, destroying the dynamic balance of demineralization and remineralization of dental hard tissues, and causing demineralization and caries. Dental plaque is a common cause of caries and periodontal disease. The detection of dental plaque is of great significance for the prevention of oral diseases. Since the human naked eye cannot directly observe the dent...
