Objectives: This study aimed at helping oral health prevention of the blind and related management plan, which is defined as the influence factors between missing and filled permanent teeth index and general feature and oral health behavior of the blind in Korea (estimates 229,678 persons) using data of the 6th Korea National Health and Nutrition Examination Survey from 2014 Korea Centers For Disease Control and Prevention. Methods: The blind over the age of 30 were selected as study subjects who have conducted health survey and dental inspections in KNHANES VI-2. Estimates of the subjects were 229,67 persons. For analyzing data, general linear models: GLM and covariance analysis were conducted to identify the relation between general feature and oral health behavior and missing and filled permanent teeth index. SPSS 21 statistical program was used, which is possible to conduct complex sampling design, and the significance level was 0.05. Results: The missing and filled permanent teeth index was 8.58 points. Regarding the results of the analysis, R-squared of the missing and filled permanent teeth index depending on general features of the blind was 0.839 points, which shows gender, age, residence, education level, individual income, disability rating, kinds of health insurance, marital status and recipient of basic living had an effect on the missing and filled permanent teeth index. R2 of the missing and filled permanent teeth index depending on oral health form of the blind was 0.728 points, which shows oral examination, dental treatment, smoking and toothbrushing after lunch had an effect on the missing and filled permanent teeth index. Conclusions: With the result of this study, we found the oral health actual condition of the blind in Korea. Therefore, it is considered that the government needs to introduce the personalized oral health education program to maintain oral health of the blind and to develop a program that uses braille and voice device which enables to access and utilize to improve oral health behavior that the government could use it as a reference to establish the policy plan.

Methods : The subjects in this study were performed with 235 people, who were over 65 years and resided in Daejeon Province, from June 20 to July 10, 2011. An individual interview was held, and they got a dental checkup. As for data analysis, chi-square test, t-test, one-way ANOVA, pearson correlation were utilized. Results : The older age in the whole research subjects and the lower educational level led to the less remaining teeth and the larger missing teeth index. The decayed missing filled teeth index and the decayed missing filled teeth rate were higher in more women and older age and in the lower educational level. Tooth mortality rate was higher in the older age, the lower educational level, and the group of living together with spouse. The maxillary-mandibular fixed-bridge status in the mouth was indicated to be the highest in the full-denture mounting ratio as for elders in over 80 years old. Oral Health Impact Profile(OHIP-14) average score was $56.05{\pm}11.64$ in the whole research subjects The decayed missing filled teeth index and the decayed missing filled teeth rate showed significantly positive correlation with the decayed missing filled teeth rate, tooth mortality rate and showed significantly negative correlation with OHIP-14. Tooth mortality rate showed significantly negative correlation with OHIP-14 Oral Health Impact Profile(OHIP-14) showed significantly positive correlation with its factors. Conclusions : Accordingly, the policy effort is considered to be necessary that implements in elders in order to spend active senescence, and that elders' health and oral-health behavior can be implemented continuously and preventively through classification according to elders' physical function.

Objectives: This study was taken to investigate factors related to dental caries in deciduous teeth of preschool children. Methods : this study was completed by oral examination on 623 kindergarten pupils and questionnaire on their mothers in Sangju city from April 1 to May 20, 2001. Study design is Cross-sectional Study. Results: The mean values for decayed teeth indexed(dt index), filled teeth index(ft index), and decayed and filled teeth index(dft index) was 2.46, 1.85, and 4.30 respectively. 2.05 for girl was significantly lower than 2.77 of boy in gender (p<0.01). As child ren got older, values were higher(0.7 and 2.84 of three years old, 1.6 and 4.01 of four, 2.42 and 5.02 of five) in ft and dft index(p<0.001). Also, Mother age was almost same, that is, 4.12 dft value for 30~34 years was smaller than 6.17 for above forties(p<0.001). 2.07 and 4.68 for mothers who graduated from high school were higher than 1.36 and 3.34 for university in the ft and dft index(p<0.05), that is, the more they had a high educational level, the lower they got a values. Value 2.76 for children who had non cariogenic food was lower than 5.11 for those who had cariogenic food in dft index(p<0.001). In dft index, 3.82 of children who have learned the education on oral health from mother frequently have lower than 45 of children who have never learned (p<0.05). The ft value of children who had a snack food with mother(1.29) was a smaller than children had it at out of home(1.97)(p<0.05).
