Abstract
[한글]
심미성 수복재료의 구치부용 복합레진은 점차 널리 사용되어지고 있는바, 교합압에 저항할 수 있는 적절한 형태의 와동을 형성하기 위하여 폭과 깊이에 따른 압축강도를 측정하여 다음과 같은 결과를 얻었다.
Ⅰ. 각 와동형태에 따라 압축강도의 통계적 유의성이 있었다(P<0.05).
Ⅱ. 두 종류의 복합레진의 와동형태에 따른 통계적 유의성은 없었다(P>0.05).
Ⅲ. 깊이 3mm의 군에서 폭 증가시 통계적 유의성이 있었다(P<0.05).

Composite resins has been widely used in dental clinics because of esthetic restoration.
The aim of this study was to assess the effects of the cavity designs on the compressive stress of resin restoration.
So, the author made the standardized specimen of four types(Type of speciemen are width 1.5mm, depth 2mm, width 1.5mm, depth 3mm, width 2mm, depth 2mm, width 2mm, depth 3mm). The compressive strength was measured by universal testing machine(Tong Kwang Co.)
The results indicating following;
1. There was a statistic significance of compressive strength between four cavity forms.
2. There was no difference of significance of compressive strength between two resins.
3. There was a significance of compressive strength between depth 3mm width 1.5mm and depth 3mm width 2mm.
