Abstract：AIM:To compare the microleakage of Ceramage polymerization ceramic inlay after cemented by 4 kinds of resin cement.METHODS:Mesial-occlusal cavity was prepared on 40 extracted caries free premolars.40 Ceramage polymerization ceramic inlays were made and were cemented into the cavities of the teeth by Rely X ARC, Rely X Unicem,Panavia F and ResiCem respectively(n =10).After 500 psychro-thermal cycles,the teeth were stained by fuchsin.The inlays were cut longetively and dye penetration was measured under microscope.RESULTS:In terms of shaft wall,significant difference in microleakage was found among the 4 groups by single factor analysis of variance (F=8.04,P<0.05).Microleakage of Group Rely X Unicem was significantly higher than that of group Re-ly X ARC (q=6.56),group Panavia F(q=5.579)and group ResiCem (q=5.158),(P<0.05).No significant difference was found among the other three groups(P>0.05).In terms of gingival wall,no statistically significant difference of microleakage was found among the 4 groups (F=2.112,P>0.05).In all groups,microleakage in gin-gival wall was significantly higher than that in shaft wall(P<0.05).CONCLUSION:The cementing effect of Rely X Unicem is the poorest among the 4 resin cements.
