Periodontal disease is one of the core factors affecting oral health and one of the four most common diseases of the oral cavity. There are many causes of periodontal disease, and poor oral hygiene habits are the main culprits that lead adults to contract periodontal disease. Incorrect oral hygiene habits make pathogenic bacteria triggered periodontal disease, and dental malocclusion, smoking, alcoholism, mental stress, irregular work and rest, unbalanced diet and nutrition may further aggravate periodontal lesions. However, many people do not take this seriously until the lesions destroy the periodontal fibers, resulting in pus, alveolar bone resorption, gum recession, loose teeth and even loss of attention. In 2007, China’s third national oral health epidemiology sample survey results have shown that China’s middle-aged and elderly periodontal health rate of 14.5% and 14.1%, and most of them have not been effectively treated. Currently, periodontitis has surpassed dental caries as the leading cause of tooth loss among adults over 35 years of age in China, therefore, improving the oral health of the general public is a very important public health task at present. “Disease enters through the mouth, and an unhealthy mouth poses a threat to general health, leading to and exacerbating many systemic diseases.” In recent years, studies have found that the formation of peptic ulcers is related to the presence of Helicobacter pylori, and many scholars believe that the latter is the main reason for the development of peptic ulcers, while some patients with periodontal disease have a large number of Helicobacter pylori in oral plaque, and the drugs can easily remove Helicobacter pylori in the stomach and intestine, but it is very difficult to remove Helicobacter pylori in the plaque; diabetic patients are often complicated with varying degrees of oral lesions The incidence of periodontal disease is also high, and the lesion damage is severe and rapid. At the same time, patients with insulin-dependent diabetes mellitus with severe periodontitis have significantly poorer glycemic control than patients without periodontal disease; patients with periodontitis have a higher incidence of coronary heart disease and stroke than people with normal periodontitis; periodontal disease as an infectious lesion can also cause a variety of inflammatory disorders, and the causative organisms and their toxins can invade the bloodstream, aggravating or causing subacute infective endocarditis, rheumatoid or rheumatoid arthritis, glomerulonephritis, and can also cause certain skin diseases. Periodontal inflammation can also lead to weakness in chewing, reducing the chewing function, causing partiality and loss of appetite, leading to weakening of gastrointestinal digestion and absorption, malnutrition, and affecting growth and development.
