| Abstract | ||||
| Objective: this study aimed to compare microleakage of conventional glass-ionomer cement , highly viscous glass-ionomer cement (HVGIC), resin cement and resin modified glass-ionomer cement (RMGIC) with prefabricated posterior NuSmile® ZR crowns. Materials and Methods: forty prefabricated Nusmile zirconia crowns for lower primary second molars were cemented by different four types of cements. Group I: ten of crowns were cemented by ketac cement, Group II: ten of crowns were cemented by fuji IX cement, Group III: ten of crowns were cemented by panavia SA auto-mix cement and Group IV: ten of crowns were cemented by fuji II cement. After thermo-cycling, microleakage was evaluated to all of groups. Results: The results of ANOVA meaning there was a highly significant difference between groups, especially between GII (High viscous GIC) which had the highest mean of microleakage and GIII (Resin cement) which had the lowest mean of microleakage. Conclusion: after thermo-cycling resin cement (group III) showed the least microleakage with prefabricated Nusmile zirconia crowns, resin modified GIC Group (IV) showed more microleakage than resin cement ,conventional GIC (Group I )showed more microleakage than resin and modified resin GIC and Group II high packable GIC (fuji IX) had the highest microleakage. | ||||
