한국인의 연령별 영구치 치아우식증 양상을 알아보고자 2000년도 국민구강건강실태조사에 근거하여 영구치 치아우식증 상태에 대한 분석을 시행하였다. 영구치가 맹출하기 시작하는 시기인 6세 이상만을 연구대상으로 선정하여 연령별 DMFT 분포, DMFT index와 SiC index, 치열 내 치아종류별 우식유병률과 제1대구치에서 치면별 우식증 상태에 대해 조사하여 다음과 같은 결과를 얻었다.1. 치아우식증은 모든 연령에서 정규분포하지 않았으며 우식병소의 대부분을 차지하는 소수의 집단, 즉 치아우식증 고위험군이 존재함을 확인하였고, 우식유병률이 한쪽으로 치우친 분포 양상(rightly skewed distribution)을 나타내었으며, 이러한 편향성(skewness)은 연령이 낮아질수록 두드러졌다. 2. 12세 아동의 DMFT index는 2.86, SiC index는 6.14로 나타났다..3. SiC index는 DMFT index보다 약 1.4~3.0배 높았다.4. 성별 분석에서 DMFT index는 모든 연령에서 남자보다 여자가 높았고(p<0.01), SiC index는 6-8세, 10-13세에서 남자보다 여자가 높았다(p<0.05). 5. 지역별 분석에서 DMFT index는 8세, 14세에서는 농촌보다 도시가, 60-69세는 도시보다 농촌이 높았고, SiC index는 6-8세, 14세, 30-49세는 도시보다 농촌이 높았고, 60세 이상에서는 농촌보다 도시가 통계적으로 유의하게 높았다(p<0.05). 6. DMFT index와 SiC index를 구성성분인 우식, 충전, 상실로 나누어 분석한 결과 6세에서는 우식이, 7세에서 49세까지는 충전이, 50세 이후로는 상실이 가장 주된 구성요소였다.7. 치열 내 치아종류별 우식경험률은 제1대구치가 가장 높았으며, 상악 제1대구치보다 하악 제1대구치가 더 높았다.8. 치면별 우식경험 분석에서 상악 제1대구치는 6세에서 49세까지는 교합면, 설면, 근심면, 원심면, 협면 순으로 50세 이후로는 교합면, 근심면, 원심면, 설면, 협면 순으로, 하악 제1대구치는 6세에서 29세까지는 교합면, 협면, 근심면, 원심면, 설면 순으로 30세 이후로는 교합면, 협면, 원심면, 근심면, 설면 순으로 우식 및 충전이 많은 것으로 나타났으며, 우식 및 충전에 가장 많이 이환된 치면이 교합면이었다. 9. 제1대구치를 상실하게 되는 가장 주된 원인은 우식이었다. 따라서 본 연구 결과 SiC index는 우식경험을 나타내는 새로운 지수로 이용될 수 있으며, 이 새로운 지수로 치아우식증 고위험군에 대한 자료를 확보할 수 있을 것이라 사료된다. 또한 공중구강보건 정책을 기획하고 실행함에 있어 고위험군 집중관리법으로 예방 전략의 전환이 요구될 것이고 여기서 SiC index가 유용할 것이며, 더불어 SiC index는 구강보건을 위한 새로운 목표 설정에도 이용될 수 있음을 시사하고 있다.

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 10-13 years(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 60-69 years. The SiC index in rural areas was higher than in urban areas at the age of 6-8, 14, and 30-49 years, and vice versa at the age over 60 years.6. D(Decayed) was the major component of the DMFT index by 6 years old children in Korea. F(Filled) was the major component of the DMFT index in Korean population aged 7-49 years. M(Missing) was the major component of the DMFT index in Korean population aged over 50 years. 7. Caries prevalence rate of the first permanent teeth was the most highest of all tooth types. Caries prevalence rate of the lower first permanent molar was more higher than the upper first permanent molar.8. Occlusal surfaces were the most common site for caries in first permanent molars. In upper first permanent molars, the order of caries susceptible surface sites was occlusal, palatal, mesial, distal, and buccal surfaces at the age of 6-49 years and the order was occlusal, mesial, distal, palatal, and buccal surfaces at the age over 50 years. In lower first permanent molars, the order of caries susceptible surface sites was occlusal, buccal, mesial, distal, and lingual surfaces at the age of 6-29 years and the order was occlusal, buccal, distal, mesial, and lingual surfaces at the age over 30 years.9. The major reason for missing of first permanent teeth was caries. Based on the results, the caries prevelance shows skewed distribution of the disease and there was a high caries risk group. Caries prevalence rate of the first permanent teeth was the most highest of all tooth types and occlusal surfaces were the most common site for caries in first permanent molars. The new
