유구치의 제2급 와동에서 Glass lonomer Silver Cermet Cement (Ketac-Siker**(R))으로

충전한 경우의 변연누출과 일반적인 구치부 충전재료인 구치부용 복합레진과 아말감으로

충전한 경우의 변연누출을 비교하기 위하여 치관부나 인접면에 치아우식증, 충전물, 파

절등의 육안적 결함이 없는 68개의 유구치를 선택하여 93개의 제2급 파동을 형성하여 3군

으로 분류한후 제1군은 Ketac-Silver, 제2군은 P-50, 제3군은 Amalgam으로 충전한후 Meth

ylene Blue를 이용한 색소침투법에 의하여 변연누출을 측정하여 다음과 같은 결론을 얻었

다.

1. 교합 변연부와 치은 변연부 모두에서 Ketac-Silver충전군의 변연누출은 P-50충전군

에 비하여 유의성있게 크게 나타났으며 Amalgam충전군에 비하여 유의성있게 적게 나타났

다.

2. 모든 실험군에서 치은 변연부의 변연누출이 교합변연부외 변연누출보다 크게 나타났

으며 통계학적인 유의성이 있었다.





AN EXPERIMENTAL STUDY OF MICROLEAKAGE IN CLASS Ⅱ FILLING ON PRIMARY MOLARS WITH

GLASS I0NOMER SILVER CERMET CEMENT (KETAC SILVER**(R))

The propose of this study is the comparision of marginal leakage of the cases

filled with glass ionomer silver cermet cement (Ketac silver) and those of

posterior composite resin and amalgam which have been widely used as filling

materials in class Ⅱ cavity of primary molars.

The experimental primary molars were selected without any sign of dental caries,

filling bodys, tooth fracture and gross defects.

93 cavities were prepared and randomly divided into 3 group : the first group

were filled with Ketac silver, the second group were filled with P-50 as posterior

composite resin and the third group were filled with amalgam, resfectively.

Dye penetration method with methylene blue was applied for measuring marginal

leakage of 3 groups and the conclusion obtained was as follows ;

1. Marginal leakage of Ketac silver filling group was greater than P-50 filling

group and lessor than Amalgam filling group in occlusal, gingival margin and the

results showed statistical significance.

2. The gingival leakage was greater than occlusal marginal leakage in all groups

and this result showed statistical significance.
