不同粘接剂对金属烤瓷冠边缘微渗漏影响的研究
A comparative study of marginal microleakage using different cements in porcelain-fused-to-metal crown
摘要
Abstract
Objective To evaluate the marginal microleakage of porcelain-fused-to-metal crown truing four different cement. Methods Sixteen porcelain-fused-to-metal crowns were built and randomly divided into 4 group, luted onto standard prepared human forward molars using four different cements (glass ianomer cement, resin-modified giass ionomer cement, PanaviaF, Super-Bond C&B adhesive luting system). After temperature cycling test, all the crowns were then submerged in 2% fuchsin for 24 h. The marginal microlenkage at tooth cement interfaces was observed uaing light stereomicroscopy and evaluated in clarification index. The marginal microleakage grade of 4 groups were analyzed by SPSS 13.0. Results The PanaviaF demonstrated the least marginal microleakage, Super-Bond C&B adhesive luting system, resin-medified glass ionomer cement showed an intermediate level of marginal microleakage, glass ionomet cement was aasociated with severe marginal microleakage (total, X2=157.60, P<0.01; among the different groupa,P<0.05). Conclusion Adhesive resin luting system which is the first selection in clinical is better than glass ionomer cement and is good at porcelain-fused-to-metal crown.关键词
