Periodontal disease includes gingivitis and periodontitis. Periodontal disease can develop regardless of age and race. According to the 1995-1998 oral health epidemiological survey in China, about 80% of the 12-18 age group suffer from periodontal disease, and more than 98% of the 35-44 age group. Therefore, people and adults are at risk of periodontal disease. In addition, periodontal disease is a chronic disease, the early symptoms are not very obvious, it is easy to be ignored. However, as time passes, its destructive power is superimposed, and in advanced stages, treatment is very unsatisfactory, and in some cases, the diseased teeth even have to be extracted. Periodontal disease is the disease that occurs in the periodontal tissues and is primarily inflammatory in nature. Inflammatory periodontal diseases can be divided into two main categories: gingivitis and periodontitis. Gingivitis occurs mostly in adolescents, and the tissue changes caused by the disease can be completely restored to normal after treatment; some gingivitis cannot become periodontitis if it is prolonged. Periodontitis occurs mostly in adults, and its lesions affect the gums, alveolar bone, and periodontal membrane. The tissue changes caused by the disease are difficult to recover after thorough treatment. Formation: Plaque is the most important causative factor of periodontal disease, and all other factors act through plaque. Periodontal disease can be avoided and eliminated with complete control of plaque. Tartar can be found as a layer of yellow or brown material that builds up at the junction of the teeth and gums when you look in the mirror, or sometimes you may feel a very hard piece coming off your teeth. There are two conditions for the formation of tartar, one is the mineralized core and the other is the deposition of minerals. The bacteria within the plaque is the main mineralized center, and minerals such as calcium and phosphorus come mainly from saliva and are mostly deposited on the plaque in the form of calcium hydrogen phosphate, forming tartar. Tartar is very closely related to periodontal disease, with a positive correlation between the amount of tartar and gum inflammation. It constitutes an environment for plaque to attach and breed, preventing the implementation of oral oral health care and causing more plaque to form. Therefore, in order to protect your teeth, in addition to carefully brushing your teeth every day to remove plaque, regular dental cleaning to remove tartar is also necessary. In addition, there are some etiologic factors that can lead to periodontal disease. The surface of tooth filling (filling) is not smooth or the medication sealed by endodontic treatment spills out of the tooth; the edge of crown (braces) is not tightly fitted and the edge is not properly positioned; poorly restored prosthesis; orthodontic treatment is too strong and too fast, and the metal piece on the tooth is too much extended to the subgingival area. Prevention of periodontal disease First of all, we should develop good oral hygiene habits and insist on brushing teeth after meals; secondly, remove plaque and tartar that cause gingivitis; thirdly, control deep periodontal tissue lesions that have occurred, eliminate trauma, fix loose teeth and extract teeth that cannot be retained; fourthly, carry out gum massage and percussion points to enhance periodontal tissue health; fifthly, enhance physical fitness and adjust the organism to strengthen local resistance. Early examination, early detection and early treatment are necessary. Tooth loosening and displacement, periodontal tissue and alveolar bone damage to a certain extent can produce symptoms such as loose teeth and chewing without. It can also cause teeth to shift and larger gaps to appear. In our daily life, the easiest and simplest sign to detect periodontal disease is bleeding gums while brushing teeth. Please remember: healthy gums do not bleed when brushing. Also, if you feel that your gums are dark red or bright red, your mouth smells bad, your teeth are loose, your teeth are elongated, you are weak in chewing, and your gums are abscessed, you should be alert to whether you have periodontal disease. Prevention and treatment methods: Frankly speaking, so far, there is no special medicine to treat periodontal disease. The most effective way to treat periodontal disease is to use mechanical methods such as scaling and scraping to completely remove the plaque and tartar attached to the surface of crowns and roots. This effect cannot be achieved by medication alone, which can only reduce inflammation. Scaling: commonly known as “scaling”, is one of the basic means of periodontal treatment. It usually takes 2-3 times to clean the whole mouth thoroughly. Through scaling, the tartar and most of the pigment such as tobacco plaque on the surface of teeth will be removed, and then the mouth will be fresh and the gum bleeding will be reduced or even disappeared. The method of preventing dental caries: Firstly, we should develop good oral hygiene habit, insist on brushing teeth after meals; secondly, remove the plaque and tartar that cause gingivitis; thirdly, control the deep periodontal tissue lesion that has occurred, eliminate the trauma, fix the loose teeth and extract the teeth that cannot be kept; fourthly, carry out gum massage and percussion to improve the health of periodontal tissue; fifthly, enhance the physical fitness and adjust the body to strengthen the local resistance. Early examination, early detection and early treatment are necessary. Good oral hygiene habits to develop Brush your teeth, in fact, the toothbrush was invented by the Chinese. When you read “Dream of the Red Chamber”, it was recorded that Jia Baoyu and the girls of Da Guan Yuan brushed their teeth in the morning and in the evening. It can be seen that the ancient people began to pay attention to oral health care. Modern science also proves that mechanical means such as brushing is the most effective way to remove plaque. Therefore brushing becomes a lifelong task for you. Toothbrushes should be small-headed toothbrushes with bristles that are not too hard, preferably bristle brushes. The brush handle should be long enough for easy grip. Toothbrushes should generally be replaced after 3-6 months of use because long-used toothbrushes contain a lot of bacteria. Cardiovascular doctors also believe that there is a direct relationship between acute myocardial infarction and poor oral hygiene. Therefore, doctors suggest that cardiovascular patients should pay more attention to improve their oral hygiene, it is best to periodontal cleaning once every 6 months, ask the dentist to use ultrasonic cleaning instrument to remove tartar, tartar and plaque around the teeth thoroughly, which can significantly reduce the pathogenic bacteria in the mouth, thus preventing bacteria and toxins from invading the blood, reducing the blood side of the abnormal, to prevent the occurrence of acute myocardial infarction. Oral health care for the middle-aged and elderly 1, found to have “high tooth tip”, should go to the hospital as soon as possible to ask the dentist to grind away the high tooth tip; 2, timely set the missing teeth to restore or maintain a better chewing function; 3, adhere to dozens of morning and evening knocking exercise; 4, moderate amount of rough fiber-rich food; 5, the conditions of the middle-aged and elderly, should be regularly Go to the hospital for dental examination to treat early dental diseases.
