Description

Dental plaque monitoring method, monitoring equipment, monitoring system, storage equipment and toothbrush

Technical Field

The invention relates to the technical field of tooth brushing detection, in particular to a dental plaque monitoring method, monitoring equipment, a monitoring system, storage equipment and a toothbrush.

Background

Dental plaque is a biofilm that gradually deposits on the surface of teeth, consisting mainly of food residues, shed oral epithelial cells and saliva. After plaque builds up to a certain thickness, it provides a good survival condition for streptococci and other anaerobic bacteria that are common in the normal oral cavity. Bacteria in the mouth, which are close to the tooth surface, start to transfer to anaerobic respiration because of being isolated from air, so that the generated acid cannot be diluted and washed away by saliva in time, thereby corroding enamel and promoting the formation of dental caries. When plaque accumulated at the root of teeth approaches the gums, toxins and other harmful substances produced by bacteria can irritate the gums, leading to periodontal diseases such as caries and gingivitis. If the control is not carried out any more, gingivitis can develop into irreversible periodontitis, so that the alveolar bone is damaged, and finally the teeth are loosened or shed.

In people's life, tooth brushing is an important self-oral health care method for removing dental plaque. To guide users to brush their teeth correctly, tooth brushing monitoring devices are emerging on the market that monitor the user's tooth brushing process data. The tooth brushing monitoring device is connected to the toothbrush handle to detect tooth brushing behaviors of a user, obtain tooth brushing process data, and then analyze the tooth brushing process data to obtain tooth brushing results.

In carrying out the present invention, the inventors have found that in the prior art, dental plaque data is obtained by counting the area of plaque after staining a dental surface or by examining the bulk of plaque by a periodontal probe.
