목적: 중합방법 및 측정시기에 따른 여러 이중중합 레진 시멘트의 기계적 성질인 압축강도와 간접인장강도를 비교 평가하는 것이다. 연구 재료 및 방법: 1개의 레진강화형 글래스아이오노머 시멘트인 FujiCEM 2, 2개의 전통적인 이중중합 레진 시멘트인 RelyX ARC와 Multilink N, 2개의 이중중합 자가접착 레진 시멘트인 RelyX U200과 G-CEM LinkAce를 사용하였다. 제조사의 지시에 따라 시멘트를 혼합하여 압축강도와 간접인장강도 측정을 위한 시편을 제작하였다. 중합방법 및 측정시기의 영향을 평가하기 위해 시멘트에 따라 4가지 실험 조건으로 나눴고, 만능시험기로 압축강도와 간접인장강도 측정하였다. 각각의 강도 값을 계산 후 통계처리 하였다. 결과: 압축강도에서는 RelyX ARC의 광중합과 Multilink N의 광중합, 간접인장강도에서는 RelyX ARC의 광중합을 제외하고 모든 중합방법에서 24시간 뒤 측정된 강도가 즉시 측정한 강도보다 더 높은 값을 보여주었다. FujiCEM 2는 시멘트간 비교에서 가장 낮은 강도 값을 보였다(P < 0.05). 결론: 치과용 시멘트 중에서 최근 출시된 이중중합 자가접착 레진 시멘트는 기존의 레진 시멘트와 비교시 제품별로 차이가 있었으나, 압축강도와 간접인장강도에서는 유의한 차이를 보이지 않았다.
Abstract
Purpose: The purpose of this study was to evaluate the mechanical properties of several dual-cure cements by different curing modes. Materials and Methods: One resin-modified glass ionomer cement (FujiCEM 2), two conventional dual-cure resin cements (RelyX ARC, Multilink N), and two dual-cure self-adhesive resin cements (RelyX U200, G-CEM LinkAce) were used. To evaluate the influence of the curing methods, each cements divided into four conditions (n = 20); Condition 1: self-curing for 10 minutes, Condition 2: immediate after 20 seconds light-curing, Condition 3: 24 hours after self-curing, Condition 4: 24 hours after lightcuring. The compressive strength and diametral tensile strength were measured with a universal testing machine. All data were statistically analyzed using t-test, one-way ANOVA and Scheffe’s test. Results: The results showed the compressive strength and diametral tensile strength after 24 hours in all curing modes were higher than immediate except RelyX ARC light-cured and Multilink N light-cured. The FujiCEM 2 showed lowest values (P < 0.05). Conclusion: The outcome was cement-depend, but there is no significant difference about compressive strength and diametral tensile strength between dual-cure self-adhesive resin cements and conventional resin cements. And this result will be used as a base line data selecting resin cement for favorable long-term prognosis.
