Periodontal disease is the most common disease in the oral cavity, with a prevalence rate of 90% among adults. Periodontal disease causes great pain, damages health and affects the quality of life. Modern medicine proves that after suffering from periodontal disease, the gums are inflamed, bleeding, painful and bad breath in the light cases, and the periodontal tissues are destroyed in the heavy cases, causing the teeth to separate from the gums, resulting in loose and displaced teeth, sour and soft teeth, weak chewing, and even falling off, and also, many diseases can be induced, such as rheumatism, depression, heart disease, blood disease, etc. What is periodontal disease? Periodontal disease is a disease of the supporting tissues of the teeth, including the gums, bone, periodontal ligaments and alveolar bone due to inflammation, and is one of the most common oral diseases and a major cause of tooth loss. However, not all of these tissues are affected at the same time, and depending on the severity and extent of local inflammation, periodontal disease can actually be divided into two major categories: gingivitis and periodontitis. The gums are prone to bleeding when physically stimulated; 2. The gums in the affected area are congested and edematous, and periodontal pockets can be detected in cases of periodontitis, and the teeth are loosened to varying degrees; 3. Radiographs show varying degrees of alveolar bone resorption in cases of periodontitis, and no alveolar bone resorption in gingivitis. Clinical manifestations 1, gingivitis is mainly manifested as the gingiva and gingival papillae become round and pure, bright, dot color disappears, gingiva is soft and fragile, lack of elasticity, gingival probing easy to bleed, local tartar or calculus exists; 2, periodontitis in addition to the performance of gingivitis, there are periodontal pocket formation, periodontal pockets can have pus overflow, teeth are loose to varying degrees, radiographs can be seen in different degrees of alveolar bone resorption. The etiology of periodontal disease is mostly due to local plaque, tartar, tartar, food embedding, poor restorations, etc. Some of them can be caused by systemic diseases, such as defective R function, endocrine disorders, malnutrition, tuberculosis, kidney disease, genetics, etc. The disease can develop in all age groups, and there is no significant difference in gender. The main cause of periodontal disease is plaque, which is simply the damage caused by poor oral hygiene, the main component of the dental class is bacteria, and intermingled with some cells that have been shed in the mouth and some organic matter, but not the general chunk of food debris, plaque is usually difficult to see with the naked eye, you must use plaque stain to show, if you let the plaque grow, you will see a yellowish-white layer on the surface of the teeth. This is a very thick layer of plaque. Treatment method Western medicine treatment method of periodontal disease 1, remove local bad stimulus, remove calculus and plaque (also known as scaling) and actively treat systemic diseases; 2, more serious periodontitis feasible gingival flap surgery, gingival hyperplasia excessive feasible hyperplastic gingival resection; 3, antibiotic treatment; 4, guide patients to establish good oral hygiene and health care. For periodontal disease medication is mainly for the acute inflammation period, through the use of effective antibiotic drugs to control the development of inflammation and improve the symptoms, after the inflammation is controlled more important treatment is to carry out local treatment, such as thorough removal of tartar, tartar or removal of bad restorations, so that both the symptoms and the root cause. If the disease is caused by a systemic disease, it should be treated with medication from the relevant specialist.
