Objectives: This study aimed to analyze the variables affecting the survival of the four permanent centralincisors in an adult Korean population using logistic regression analysis. Methods: The Korean government has been collecting oral health data at the national level at 3-yearlyintervals since 2000. In addition, a national survey was conducted in 2006 of 15,777 persons aged 2 to95 years old who were stratified by age, gender, and region. The raw data were input and the relationshipbetween each of eight objective variables and tooth survival was analyzed by frequency, crosstabulation,and logistic regression analysis, with age, gender, and economic status as functional variables. The inclusion level was =0.05 and the exclusion level was =0.10. The eight variables were age,economic status (jobs), monthly family income, gender, frequency of toothbrushing per day, presence ofdiabetes, education level, and smoking years. Results: The survival rate of the incisors decreased with an increase in age, while that in individuals whoengaged in farming, stock breeding, and fishing was 5 to 7 times lower than that in individuals in toppositions in terms of jobs and society. Further, the survival rate in individuals with diabetes was 2 to 3times higher than in those without diabetes. Conclusions: The most significant predictor of the survival rate of the four permanent incisors in Koreanadults was age, followed by economic status and presence of diabetes.

Objectives: This study aimed to analyze the variables affecting the survival of the four permanent first molars in an adult Korean population using logistic regression analysis. Methods: The Korean government has been collecting oral health data at the national level at 3-year intervals since 2000. In addition, a national survey was conducted in 2006 among 15,777 persons aged 2-95 years who were stratified by age, gender, and region. The relationship between each of nine objective variables and tooth survival was analyzed by frequency, cross-tabulation, and logistic regression analysis, with age, gender, and economic status as functional variables. The inclusion level was α=0.05 and the exclusion level was α=0.10. The nine variables were age, occupational status, monthly family income, gender, frequency of brushing the teeth, snack intake per day, presence of diabetes, education level, and smoking (packs per year). Results: The survival rate of the molars decreased with increased age. In individuals who engaged in farming, stock breeding, and fishing, the rate was 2-5 times lower than that of individuals in higher positions in terms of jobs and society. Furthermore, the survival rate for smokers was 5-10 percent lower, compared with non-smokers. Conclusions: The most significant predictor of the survival rate of the four permanent molars in Korean adults was age, followed by jobs, smoking, and gender.
