The purpose of this study was to analyze the reasons and mean age for tooth extraction among patients living in Busan city. The researcher observed 1,119 patients' teeth extracted due to dental caries, periodontal disease and other reasons. This study examined the reasons for tooth extraction by age, sex, and tooth-kind. The reasons for tooth extraction were dental caries, periodontal disease, eruption problems and others. The obtained results were as follows; 1. Among the reasons for tooth extraction, dental caries accounted for 25.9%, periodontal disease 56.5%. 2. Periodontal disease was the main reason for tooth extraction and continued throughout life irrespective of sex. However dental caries was remarkably increasing in those aged 30 years old and under. 3. In the extraction of permanent teeth, males outnumbered females while upper teeth did lower teeth. 4. Although the third molars were most extracted in all kinds of teeth, the main reasons for the extraction were eruption problem. 5. The mean age of the tooth extracted was 47.9 years in both sexes for the mandibular first molars and the mandibular first molars had the shortest life except third molars of total teeth. The mandibular canines had the longest life of total teeth. Because dental caries and periodontal disease are the main causes of tooth extraction in Korea, the dental health policy should be focused on the prevention and treatment of these two diseases in the government level.

This study was conducted on 1,865 drunk elderly people who had teeth that were over 65 years old. As a result of analysis of factors related to tooth extraction, the higher the income, the lower the income, the higher the risk of having to remove teeth from smokers, poorer oral health status, and no oral hygiene products. The difference was statistically significant. In order to identify the risk factors of tooth extraction for the elderly and prevent tooth loss early and to extend the life of residual teeth as much as possible, it is necessary to improve the drinking culture and seek oral health care strategies in the previous life cycle, not the present, Oral health policy should be pursued.

This study used raw data from the 2013-2015 National Health and Nutrition Survey, and conducted a multivariate logistic regression analysis to identify factors related to teeth extraction from Korean elderly aged 65 and older (4.037). As a result, the risk of tooth extraction was 1.84 times higher in males, 1.52 times in age 75 or older, 2.36 times higher in income, 2.04 times higher in income, and 1.44 times higher in smokers. The results were statistically significant as 1.49 times without oral examination and 2.30 times without dental treatment for 1 year. Through this, the current health behavior and oral health behavior can reinforce the basis of risk factors related to the need for tooth extraction. At the national level, we need to look for diversification.
