Periodontitis is a chronic inflammatory disease that invades the gum and periodontal tissues and is a destructive disease characterized by the formation of periodontal pockets and inflammation of the pockets’ walls, resorption of the alveolar bone and gradual loosening of the teeth, and it is the main cause of tooth loss in adults. The disease is mostly caused by plaque, tartar, food impaction, poor restorations, bite wounds, etc. The gums become inflamed and swollen, while the plaque buildup increases and expands from supragingival to subgingival. Due to the characteristics of the subgingival microecological environment, the subgingival plaque contains a large number of virulent periodontal pathogenic bacteria, such as Bacillus gingivalis, Bacillus intermedius and Spirochetes, which aggravate and extend the inflammation of the gums, leading to the formation of periodontal pockets and alveolar bone resorption, resulting in periodontitis. Periodontitis has been identified by the medical community as the third largest killer of human health after cancer and cardiovascular disease, and is also the “number one killer” of oral health. Periodontitis has a number of pre-existing symptoms, and has become the main feature of the deterioration of oral “subhealth”. The vast majority of patients with periodontitis are accompanied by symptoms of gum recession, the survey found that in people over 45 years of age, more than 90% of the existence of varying degrees of gum recession, and gum recession, has always been the dental profession as irreversible physiological degeneration phenomenon. It is important to note that due to genetic, environmental, and food safety factors, the physiological degeneration of gingival recession has a tendency to decrease in age year by year, with the youngest patient with gingival recession being 18 years old. According to the latest research findings, due to the reduction or cessation of the secretion of certain growth hormones in the pituitary gland of adults, it will lead to serious impairment in the absorption of vitamin C in the mouth and gums, thus bringing about serious malnutrition in the mouth and gums, and the serious consequences of this malnutrition are reflected in the reality that the physiological degeneration of gum recession is greatly advanced, which is also the reason why, despite the importance people attach to oral cleaning such as tooth brushing, gum recession is still increasing. This is the fundamental reason why gingival recession is still increasingly present at a younger age, despite the importance people attach to oral cleaning such as brushing. The direct effect of gum recession is that the natural barrier that protects teeth and subgingival periodontal tissues is opened, causing various food residues and dirt in the mouth to cross the protection of healthy gums and invade the subgingival area, which is a “dead zone” of oral hygiene that cannot be cleaned by regular brushing, and accumulates for a long time to form tartar. Tartar is an indispensable “carrier” for the growth of various harmful periodontal bacteria under the gums, and due to gum recession, anaerobic bacteria can breed and spread under the gums, and attack the health of the gums and periodontal tissues for a long time; at the same time, as mentioned above, due to the malnutrition of the gums, this will lead to the growth of the adult oral resistance to disease. As a result, the ability of the adult oral cavity to resist disease declines dramatically with age, leading to various gingivitis, periodontitis, and pulpitis symptoms. These inflammatory diseases, especially periodontal disease, under the traditional treatment means difficult to completely cure the helpless, is due to the periodontal disease can be constantly recurring characteristics, and further endanger the health of the gums, back to more aggravate the degeneration of gum recession, resulting in loose teeth and early loss, missing, also make periodontal disease has become the cause of dental “non-healthy The main source of dental “non-healthy” diseases. Various inflammatory diseases caused by toothache to the patient’s pain needless to say, because each diseased tooth, itself is a constant production, replication of a large number of germs and viruses hotbed, every day through the blood to the whole body, and then infringed on the whole body health, at this time, the traditional oral dental treatment methods, had to take destructive extraction therapy (including tooth extraction, dental implants, root canal treatment, etc.), to stop However, this “mending” type of destructive treatment is at the expense of teeth. Therefore, how to start from the timely detection of oral and dental “subhealth” state, how to timely prevention and rehabilitation care of various oral and dental diseases hidden, is the only way to fundamentally eliminate periodontitis and avoid the deterioration of oral and dental state to “non-healthy”. The only way to prevent periodontitis and avoid the deterioration of oral and dental status to “unhealthy”.
