Abstract
결 론
저자는 발거된 소구치 120개의 치경부에 5와동을 형성하고 2종류의 복합레진으로 4가지 충
전방법에 의해 충전하고, 각각 교합변연부와 치은변연부에서 변연누출 정도를 측정하여 다
음과 같은 결론을 얻었다.
1. 교합변연부에서 SiluxR군과 Alpha-dentR군 공히 충전방법
에 따른 변연누출 정도의 차이는 없었다.
2. 치은변연부에서 SiluxR군은 여러번 나누어 충전한 군들이 한번에 충전한
군들에 비해 변연누출이 적었으며 통계학적 유의차가 있었다(P<0.05)
3. 치은변연부에서 Alpha-dentR군은 matrix를 이용해 가압한 군들이
matrix를 사용하지 않은 비가압 군들에 비해 변연누출이 적었으며 통계학적 유의차가 있었
다(P<0.05)
4. 충전방법에 관계없이 SliuxR군과 AlphadentR군에서 교합
변연부가 치은변연부 보다 변연누출이 적었으며 통계학적 유의차가 있었다(P<0.05)

The purpose of this study was to evaluate the marginal leakage of class V composite
resin restorations by the changing insertion method. The cavities were frilled with two
composite resin systems in accordance with following four insertion methods, first,
incremental with pressure, second, incremental without pressure, third, single incremental
with pressure, and fourth single in cremental without pressure. The composite resin
systems used in this study were SiluxRscotchbondR (3M
Co.) which were light curred, and Alpha-dentR Enamel
BondR which were chemically cured. All procedures were directed by
manufacturers' recommendations. All specimens were thermocycled by alternatly
immersing them in water at 4℃ and 60℃ for 100 cycles. They were immersed in 0.5%
Methylene Blue solution for 24 hours, and sectioned buccolingually through the
restorations with diamond disk into two parts. The sectioned specimens were observed
with light microscopy.
The following results were obtained.
1. No significant difference in the degree of marginal leakage was observed among
insertion methods in SiluxR groupsR at the occlusal margins.
2. At gingival margins in SiluxR groups, incremental subgroups chow
less marginal leakege com-pared with single incremental subgroups and show significant
difference between them.(P<0.05)
3. At gingival margins in Alpha-dentR Groups, pressure subgroups show
less marginal leakage compared with non-pressure subgroups and show significant
difference between them.(p<0.05)
4. At occlusal margins, SiluxR and Alpha-dentR Groups
show less marginal leakage compared with gingival margins in all insertion methods and
show significant difference between them.(p<0.05)
