Abstract
[한글]

치면열구 전쇄재의 미세누출은 관찰하기 위해서 167개의 발거된 유치 및 영구치에서 몇가지 단순한 기계적인 전처치를 법랑질 부식 전에 시행한 후, 전쇄재를 도포하고 24시간, 2달 후의 누출여부를 Ca^^45로 추적하여 다음과 같은 결과를 얻었다.

1. 전체 167개 치아 중 53개 (37%)의 누출을 보였다.

2. 시간이 경과함에 따라서 영구치에서는 24시간 후 22%가 2달 후 35%로. 유치에서는 24시간 후 32%가 2달 후 43%로 누출이 증가되었다.

3. 법랑질 부식전의 전처치 내용에 의하면 유치 및 영구치는 fluoride로 처리한 것이 50%와 33%로 가장 누출이 많았다.

4. 전체적으로 유치(38%)가 영구치(28%)보다 누출이 많았다.

The purpose of this study was to observe the microleakage of a pit and fissure sealant at the tooth-restoration interface.

One hundred and sixty-seven extracted permanent and deciduous teeth were used and some simple mechanical pretreatment were done before etching. The degree of microleakage was assessed by Ca4s after 24 hours, and 2 months.

The results were as follows :

1. Among total 167 teeth, 53 teeth (32%) were demonstrated the microleakage.

2. After 2 months the leakage was increased from 22 percent to 35 percent in permanent teeth, and from 32 percent to 43 percent in primary teeth.

3. The group treated by fluoride paste was demonstrated the largest leakage, 50 percent in primary teeth and 33 percent in permanent teeth.

4. There are more leakage in primary teeth (38%) than permanent teeth (28%).
