Periodontal disease is a common oral disease, the early symptoms are not easy to attract attention, resulting in long-term recurrent infection of periodontal tissues, and by the time patients visit the clinic, the condition is quite serious, not only damage the function of the oral chewing system, but also seriously affect the health of the whole body. The prevalence of periodontal disease in the population is up to 90% or more, covering a variety of occupations and all age groups. As a periodontist, most of the people who come to the periodontal disease clinic every day are already in a serious or very advanced condition, and in the early stage they do not recognize or take periodontal disease seriously, and many of them not only do not accept the doctor’s advice for regular treatment, but also have serious misconceptions that the doctor is scaring people. It should be clear that any disease dragged to an advanced stage, the doctor’s medical skills are no longer able to return, periodontal disease is even more so, if the timing is right periodontal disease treatment effect is very good, advanced periodontitis patients, extremely painful. Many people’s neglect of oral health gives us medical professionals a headache, and they are totally ignorant of the effects of periodontal disease on oral health and general health. The impact of periodontal disease on oral health: First, depending on the extent of the disease, there can be gum redness, bleeding, bad breath, loose teeth, chewing weakness and even pain. Secondly, once the teeth are missing, trouble will ensue, and dentures will not only be costly, but also bring endless consequences. No matter which restoration method you choose, it will not be perfect: (1) movable denture repair every day to take off and clean, some people feel that movable denture wear in the mouth will be very uncomfortable, chewing effect is very poor, the cosmetic effect is not good, simply throw aside not to wear, or some dentures with a few years, the adjacent teeth often loose again, so most people are willing to set the fixed kind. (2) fixed restoration is the use of abutment teeth (good teeth next to the missing teeth) on the installation of the crown set, do not have to take off, but the teeth next to be ground out a thick layer, in order to leave enough space for the crown set to repair the missing teeth, in this process, the teeth next to the likely to discomfort, pain and other symptoms, and even to sacrifice the nerve. With the use of dentures for a longer period of time may appear on the abutment teeth and periodontal tissue, a variety of problems such as secondary caries (good teeth out of the hole), gingivitis, pulpitis, tooth or root fracture or fracture, crown loss, resulting in the eventual loss of abutment teeth, so the loss of more and more teeth, the difficulty of setting teeth has increased, some people even eventually can not set dentures, even to maintain the basic life It is very painful because they can’t even maintain three meals a day. (3) Of course, the emergence of dental implant restoration is relatively minimal damage to the good teeth, it is in the gap between the missing teeth in the alveolar bone, plant a nail implant, so that it and the bone completely grow together, and then on the basis of this set a porcelain teeth. This type of restoration is good in terms of chewing function and aesthetics, but it requires a high enough height and thickness of the dental bed (bone grafting if the dental bed is not enough) and is expensive (about 10,000 RMB). In case of peri-implantitis, implant failure may also occur. This shows how important it is to keep your teeth! The impact of periodontal disease on systemic health: In periodontitis, a large number of bacteria gather on the tooth surface and periodontal pocket wall, the epithelial thinning of the periodontal pocket wall and the structural integrity of the surface are damaged, forming a vesicular ulcer surface, and when there is a large accumulation of bacteria on the broken surface of the periodontal pocket, daily chewing activities can cause bacteria and toxic products to enter the blood circulation, increasing the risk of systemic disease. Recent studies have shown that periodontitis has become a risk factor for a number of systemic diseases and a direct threat to systemic health! Bacterial infection during periodontitis not only acts directly on the cardiovascular system, but also induces an immune and inflammatory response throughout the host’s body. Studies have shown that periodontal disease is associated with the development of stroke and myocardial infarction. The relationship between periodontitis and diabetes is bidirectional and affects each other. Patients with periodontitis have a higher rate of diabetes than those with healthy periodontium, and their blood glucose is not easily controlled. Periodontitis is now ranked as the 6th most common complication of diabetes, and diabetic patients are more likely to develop periodontal disease than non-diabetic patients, with a high incidence of periodontal disease, severe and rapidly progressive lesions, and often associated with gum abscesses and periodontal abscesses. Pregnant women with severe periodontitis have a 5-7 times higher risk of preterm low birth weight newborns than those with healthy periodontium. The oral cavity is another site of H. pylori (Hp) colonization and has been detected on oral mucosal surfaces, in saliva and dental plaque, with the highest detection rate in subgingival plaque. H. pylori is an important causative agent of chronic gastritis and peptic ulcers, and is strongly associated with the development of gastric cancer, and periodontal treatment reduces the likelihood of gastric disease. In addition, periodontal disease is associated with respiratory infections, rheumatoid arthritis, kidney disease, and other systemic diseases, causing various diseases with extremely high mortality rates. This shows how necessary it is to treat one’s periodontal disease early and promptly!
