(A) study on dental health status and their decennial comparisons of Korean college girl students

치의학과/석사[한글] 저자는 서울시내에 소재한 E여대에 재학중인 학생에 대한 구강진사를 시행하여 그 중 15-22세에 해당하는 2,243명의 치아 우식증 및 수복물에 대하여 조사 분석하였으며. 이를 동일 기준과 방법에 의한 10년전, 20년전의 보고와 비교하여 다음과 같은 결론을 얻었다. 1. 평균 현존치아수는 28.86±1.65개로 1968년의 29.00±1.97개 1978년의 28.97±1.64개에 비하여 차이가 없었다. 2. 우식 이환률은 86.22%로 1968년의 83.25%, 1978년의 84.72%에 비하여 볼 때 지속적인 증가추세를 보였다. 3. DMF index는 19.98로 1968년의 14.56, 1978년의 15.51에 비하여 높았다. 4. DMFT수는 일인당 5.75±5.04개로 1968년의 4.23±3.88개. 1978년의 4.49±3.69개에 비하여 증가하였다. Ⅰ) 평균 우식치아수는 1.14±1.53개로 1968년의 1.16±1.57개, 1978년의 2.09±2.16개에 비하여 감소하였다. Ⅱ) 평균 결손치아수는 0.23±0.73개로 1968년의 0.691±1.11개, 1978년의 0.32±0.79개에 비하여 감소하였다. Ⅲ) 평균 충전치아수는 4.39±4.91개로 1968년의 2.35±3.33개, 1978년의 2.09±3.17개에 비하여 현저히 증가하였다. 5. 충전 재료별 관찰에 의하면 아말감, 금 인레이, 복합레진등의 crown을 제외한 단일 충전물이 90.5%로 1968년의 72.8%, 1978년의 83.6%에 비하여 증가하였다. 반면 crown 및 bridge는 각각 6.5%, 3.0%로 1968년의 12.1%, 15.1%, 1978년의 8.7%, 7.7%에 비하여 계속 감소추세를 보였다. 즉 치아발거의 감소로 보철치료는 감소된 반면 자연치아를 유지하는 보존적 치료가 계속 증가되는 추세이다. [영문] The author conducted a dental survey of college girl students and compared with that of college students 20 years and 10 years ago which based on the same criteria. The items of this survey included the prevalence of dental caries, DMFT and the kinds of restored materials. College girl students 2,294 were examined in May 1988, with the recommended criteria and method of W.H.0.. Among them, the data of 2,243 were analyzed and compared with the data of 1968 and 1978. The following results were obtained: 1. The average number of present teeth was 28.86±1.65, which does not show much difference when compared to 29.00±1.94 of 1968 and 28.97±1.64 of 1978. 2. The prevalence of dental caries was 86.22%, which increased in comparison to 83.25% of 1968 and 84.92% of 1978. 3. DMF index was 19.98, which considerably increased in comparison to 14.56 of 1968 and 15.51 of 1978. 4. The number of DMFT was 5.75±5.04 per student Compared to 4.23±3.88 of 1968 and 4.49±3.69 of 1978, there is a considerable increase. Ⅰ) The average number of decayed(D) teeth was 1.14±1.63, which decreased from 1.16±1.57 of 1968 and 2.09±2.16 of 1978. Ⅱ) The average number of missing(M) teeth was 0.23±0.73, which also decreased from 0.69±1.11 of 1968 and 0.32±0.79 of 1978. Ⅲ) The average number of filled(F) teeth was 4.39±4.91, which increased from 2.38±3.33 of 1968 and 2.09±3.17 of 1978. 5. According to the analysis of filling material, filling body including amalgam, gold inlay, resin, silicate cement and paladium inlay was 90.5%, which increased in comparison to 72.8% of 1968 and 83.6% of 1978. Among them, amalgam occupied 62.93%, which showed the most increase. On the other hand, crown and bridge was 6.5%, 3.0%, respectively, which skewed continuous decrease from 12.1%, 15.1% of 1968 and 8.7%, 7.7% of 1978. Therefore, the prosthodontic treatment reduced due to the decrease of tooth extraction. In contrast there is continuous increase of conservative treatment which maintaining natural tooth.prohibitio
