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.

The study population consisted of 1035 kindergraten children which had been selected stratified random sampling. The survey is based on WHO, 2000 oral health assessment, which has been modified. From data dt index, ft index, dft index, dt rate, ft rate, percentage of active caries, percentage of pit and fissure sealant, and so on. The findings were as follows: (1) In 5 years children, the experience of dental caries was 73.0% and the percentage with active caries was 49.4%. Dmf index was 4.13 and this observation shows a statistical singnificance. (2) Average number of 5 years children the experience of dental caries surface index was 3.11 and dfts index was 8.91. (3) The experience of dental caries fo the frist molar was 1.9% and the percentage with active caries was 1.1%. Otherwise the percentage of pit and fissure sealant of the first molar was 6.7%. It is show the low percentage for preventive dental caries. (4) Shows percentage of teeth needing treatment for one surface and above two surface was each 27.3%, 34.0%. And percentage of children required single crown and pulp treatment & single crown and tooth extraction was each 3.8%, 4.7%, 3.3%. (5) Soojung-gu and jungwon-gu were having poor oral hygiene as compared to bundang-gu. So it is necessary to establish community oral health program effectively.
