Abstract

A population-based epidemiologic survey about dental caries status of permanent teeth was conducted over 6 years old Korean people who were selected through a random sampling method. The purpose of this study was to assess the current status of caries distribution, the DMFT index, the SiC index, and tooth and surface pattern of dental caries by age. The results are as follows; 1. A detailed analysis of the caries prevelance showed skewed distribution of the disease: at specific age, a subgroup had high or very high DMFT values, while the rest of the population showed low DMFT or were totally caries-free. Therefore, expressing caries prevalence as the mean DMFT value does not correctly reflect the skewed distribution, leaving high caries groups to remain undiscovered in the population. 2. The DMFT index of the 12-year-olds was 2.86 and the Sic index was 6.14. 3. The study showed almost an linear relation between the mean DMFT values and the SiC index. The SiC index increased(decreased) by around 3 DMFT units when the mean DMFT included in this study increased(decreased) by around 2 units. 4. Females experienced more caries than males(p <0.01). The SiC index in females was higher than in males at the age of 6-8 and 10-13years(p <0.05). 5. The DMFT index in urban areas was higher than in rural areas at the age of 8 and 14 years, and vice versa at the age of 60-69years. The SiC index in rural areas was higher than in urban areas at the age of 6-8, 14, and 30-49years, and vice versa at the age over 60 years. Based on the results, the caries prevalence shows skewed distribution of the disease and there was a high caries risk group. The new 'Significant Caries Index' will be very useful to express caries experience and will provide the data about the individuals with the higher caries scores in each population. Also the SiC index will be appropriate for setting the oral health goal. Using the SiC index can lead to more specific and targeted approach focusing the interest on the high risk group.
