Description

Technical Field

[0001] The present invention belongs to the technical field of oral care, and in particular relates to a toothbrushing and oral care guidance system and method based on artificial intelligence. Background Art

[0002] Dental caries and periodontal disease are two major inherent diseases of the oral cavity. Dental caries is a bacterial disease caused by multiple factors. The lesions range from shallow to deep and can affect the enamel, dentin, and cementum. If not treated in time, the pathogenic bacteria can further penetrate into the pulp, causing pulpitis or apical periodontitis, and in severe cases, even leading to tooth loss. Dental plaque is the initiating factor of periodontal disease. Whether the plaque is controlled in time can directly affect the occurrence and prognosis of periodontal disease. Periodontal disease includes gum disease and periodontitis. The lesions spread from the gums to the periodontal membrane, alveolar bone, and cementum of the deep periodontal tissues, which can cause loose teeth, loss, and even loss of chewing function. In addition to the physical discomfort caused to patients, dental caries and periodontal disease will also seriously affect the patient's appearance like abnormal coloration, and cause psychological problems such as inferiority complex and social phobia.

[0003] Brushing teeth is a well-known oral care method. It is also the most basic and main method to remove dental plaque and reduce abnormal coloring. First of all, you should brush your teeth in the morning and evening, and brushing your teeth at night is especially important. If food residues on the tooth surface are not removed in time, it will provide bacteria with extremely rich nutrients. Bacteria can proliferate in large quantities and produce more harmful substances. During sleep, saliva secretion decreases, and these harmful substances cannot be neutralized and diluted well, which will cause serious harm to teeth. Functional toothpastes that assist in fluoride-containing anti-caries can also be used to control and prevent caries. Functional toothpastes that assist in inhibiting plaque have the effect of resisting plaque and reducing gingival inflammation.

[0004] Caries, plaque and abnormal coloring are difficult to detect, and there is no effective detection and detection equipment at home. Until the symptoms of pain appear, the best time for prevention and control has been missed, and you can only go to the hospital to spend more time, money and energy. Many people have not learned the scientific method of brushing teeth, and brushing teeth is an invisible process. If you don’t know whether your brushing method is reasonable and standard, it is easy to brush teeth ineffectively and fail to achieve the desired care effect. Summary of the invention
