Abstract

Introduction: Ceramic inlays are alternative systems for restoring dental cavities with tooth colored materials. These restorations may have some benefits over direct composite restorations such as reduction in the bulk of the cured composite. The aim of this study was to evaluate the microleakage of direct composite restorations and ceramic inlays with two different resin cements. Materials & Methods: In this experimental study, 45 class V cavities (15 teeth in each group) were prepared in buccal surfaces of human extracted molars. For 30 cavities, ceramic inlays were prepared and were cemented either with Variolin k / Excite DSC or Panavia F / ED primer. Fifteen samples were restored with Excite / Heliomolar (direct composite). Then the teeth were thermocycled and were covered with sticky wax and were immersed into the 2% Methylene blue for 48 hours. The teeth were sectioned longitudinally and dye penetration was determined. Data were statistically analyzed using nonparametric tests of Kruskal Wallis, and Mann Whitney with significance level 0.05. Results: Enamel margins showed less microleakage than dentin margins in all groups (P<0.05). No significant differences were observed between the materials used in this study (P>0.05). Conclusion: The materials used in this study can not completely prevent microlekage. It seems that ceramic inlays can not reduce microleakage over direct composite significantly. Key words: Ceramic inlays, Microleakage, Direct composite.
