Objectives : Thus this study attempted to look into the level of community residents' dental health and the state of their dental diseases and estimate the general dental health condition so that these data can be available as references in upcoming public dental health planning, and to provide fundamental data for promotion of the level of residents' dental health by performing dental health education. Methods : Among community residents who visited the department of Dental Hygiene of Shinsung University for scaling from March to May 2009, the data of total 346 subjects of 129 women and 217 men were selected, and DMFT rate, DMFT index, dental health capacity of the first permanent molar, and tooth morality rate were investigated. For statistical analysis, SPSS 14.0 was used, for general characteristics of the subjects, frequency analysis was conducted, for caries experience in the permanent teeth of the subjects, mean and standard deviation were calculated, for caries experience in the permanent teeth by sex and residence, independent t-test was performed, and for caries experience in the permanent teeth by age, one-way ANOVA was conducted. The significance level applied to these analyses was 0.05. Results : As a result of investigation and analysis on caries in the permanent teeth of community residents who visited the department for scaling in this study, the findings are as follows: 1. For sex, DMFT rate and tooth morality rate were found to be higher in women, while dental health capacity of the first permanent molar was found to be higher in men. 2. For age, DMFT rate and DMFT index were found to be highest in 40~49 years old, while DMFT rate, DMFT index, and tooth morality rate were found to be lowest in under 20 years old. Dental health capacity of the first permanent molar was found to be highest in under 20 years old, 20-29 years old, and 30-39 years old and found to be lowest in more than their sixties as 39.78 points(p<.000). Tooth morality rate was found to be highest in more than their sixties compared to other age groups.(p<.000). 3. For residence, DMFT rate and dental health capacity of the first permanent molar were found to be high in the Metropolitan area, while tooth morality rate was found to be high in Chungcheong area. Conclusions : Seen from the above-mentioned results, great importance shall be attached to the maintenance of residual teeth, and with this, efficient efforts are required to be made for upkeep and promotion of dental health.

In order to evaluate the community dental health level the actual health capacity of the lower-first permanent molar is suitable as a indicator for assessment. So we had surveyed decayed, missed and filled lower permanent first molar of 460 persons who were in the age from 20 to 29 in Iri City. The obtained results were as follows: 1. The DMFT indices of the lower first permancent molars showed in 1.40 in the age group of from 20 to 24 and 1.44 from 25 to 29. 2. The actual dental health capscities of the lower first permanent molars showed in 84.86% in the age group of from 20 to 24 and 81.03% from 25 to 29. 3. The DMF indices of the lower first permanent molars showed 15.15% in the age group of from 20 to 24 and 18.98% of from 25 to 29. 4. The DMF rates of the lower first permanent molars showed 85.66% in the age group of from 20 to 24 and 88.70% of from 25 to 29. 5. The DMF rates of the lower first permanent molars showed 70.00% in the age group of from 20 to 24 and 71.96% of from 25 to 29. 6. The DT rates of the lower first permanent molars showed 48.84% in the age group of from 20 to 24 and 39.55% of from 25 to 29. 7. The FT rates the lower first permanent molars showed 40.22% in the age group of from 20 to 24 and 43.98% of from 25 to 29. 8. The MT rates of the lower first permanent molars showed 10.94% in the age group of from 20 to 24 and 16.17% of from 25 to 29.
