Abstract

결론
불소를 유리하는 것으로 알려진 glass ionomer cement의 우식저지 효과를 연구할 목적으
로, glass cermet cement와 아말감이 원심면에 각각 충전된 유구치와 그 인접영구치에 인공
우식의 유발을 통한 실험을 실시하고, 인접영구치면에 대한 조직학적인 관찰을 시도하여 다
음과 같은 결론을 얻었다.
1. 충전후 우식유발실험에서 glass cermet cement충전군의 인접영구치의 근심면에서의 우
식병소의 깊이는 54.17±12.56μm로서, 아말감 충전군(91.67±19.51μm)에 비하여 얕게나타

#초록#
The purpose of the study was to evaluate the anticariogenic effect of glass ionomer
cement which is known to release fluoride. Artificial carious was produced on the
restored primary tooth and its adjacent permanent tooth before and after class Ⅱ glass
cermet cement restoration on distal surfaces of primary molars. Amalgam restorations
were used as control group. The specimens were processed for histologic investigation
and observed under polarized light microscope. And the lesion depths were measured on
the photos taken.
The results were as follows ;
1. In experiment of artificial carious lesion-induction after restoration, the lesion depth
of the adjacent tooth surface to glass cermet cement restoration group was 54.17±12.56
μm, which was less than of amalgam restoration group(91.67±19.51μm) (P<0.01).
2. In experiment of restoration after artificial carious induction, the depth of carious
lesion of the adjacent tooth surface to glass cermet cement restoration group was 67.50
±18.77μm, which was less than that of amalgam restoration group(120.00±21.21μm)
(P<0.01).
