First, oral health education and periodontal disease prevention and control 1, the reality of the country: 97.24% of the elderly gingival recession; 65-75 years of age, the average number of lost teeth 9.86, 10.51% of edentulous jaws; the need for oral health education up to 99.44%; oral hygiene is generally poor, the good rate of less than 1%; brushing rate has increased from 50% in 1989 to 74.18% in 2000 90% of people brush their teeth incorrectly (the effect of brushing needs to be improved). 2, the disease status of periodontal disease: in the age group of 12 to 18 years old for 75 to 88%, 35 to 44 years old age group is as high as 98%; involved in all age groups, even 5-year-old children; periodontal disease is hidden, early pain is not great, only manifested as bleeding and oral odor, is mistaken for “fire” and ignored; there are 40 More than 40% of people do not know that gum bleeding is a disease; 1/4 of people do not have the habit of brushing their teeth in the morning and evening; clinically, tooth extraction due to periodontal disease has become the first among tooth extractions, and its number accounts for 44% of the total number of tooth extractions; periodontal problems are widespread: not only in the general population, but also among medical workers, and even dental professionals have a high incidence; if they do not know they have a problem, they will not go to the hospital; if they do not know they have a problem, they will not go to the hospital. If you don’t know you have a problem, you won’t go to the hospital; you don’t think you have a problem, you don’t want to go to the hospital, you know you have a problem, but you don’t know how to go to the doctor, and the medical staff can’t give the right guidance. Misconceptions – “old tooth loss”, “toothache is not a disease”. Dental disease often does not get enough attention, many people often wait until it is really unbearable before remembering to see a doctor, delaying the time for treatment. “Losing teeth in old age” is an undesirable and unscientific concept, and is a completely avoidable phenomenon. It is possible to grow old without losing teeth! Periodontal disease is usually painless in its early stages, so you may not notice that your gums are gradually swelling, or that you occasionally bleed when you brush your teeth, or that you think it’s normal for your teeth to look longer for your age. The truth is: 80% of teens and adults have periodontal disease, and many more are unaware of it, which is why periodontal disease causes more tooth loss than all other causes of tooth loss. “Be aware of periodontal disease” is a useful advice for anyone! Several symptoms of periodontal disease bleeding gums; red and swollen gums; bad breath; receding gums; gaps starting to appear between teeth; one or more teeth starting to loosen or bite weakly and painfully; 7. unexplained pain, itching or other discomfort. Third, the cause of periodontal disease: dental plaque and its calcification formed by calculus. The calculus on the outside of the gums is usually visible, brown or black, and builds up and surrounds the neck of the teeth. However, it is the calculus hidden under the gums (subgingival calculus) that does the most damage. Preventive measures for periodontal disease: You yourself: can remove the sticky plaque on the teeth. Not able to remove calculus. Not able to remove plaque from any calculus surface.
