Title

EFFECT OF ADHESIVE CEMENTS ON REDUCTION OF MICROLEAKAGE AT THE AMALGAM/COMPOSITE-RESIN INTERFACE

Pages

  6-11

Abstract

 Background and Aim: Patients always complain about metallic color of amalgam restorations. Covering amalgam by composite can solve this problem. Since polymerization shrinkage is a serious shortcoming in composites, application of the combined amalgam and composite restoration is one of the methods to reduce leakage in the cervical margins of posterior restorations. The aim of this invitro study was to evaluate the MICROLEAKAGE of amalgam/composite interface when Rely-X ARC ADHESIVE RESIN CEMENT was used in the joint.Materials and Methods: Twenty-four sound extracted premolars were chosen. Mesial and distal class II conventional cavities were prepared and the samples were divided into 4 groups of 12. In all groups, the bases of the cavities were restored with amalgam and then the remaining part was filled by COMPOSITE RESIN. Specimens in groups 1 and 2 were restored with composite-resin, immediately after condensing amalgam without or with application of Rely-X ARC (3M, ESPE) respectively. In groups 3 and 4, COMPOSITE RESIN were applied 24 hours after condensation of amalgam, without or with application of Rely-X ARC respectively. After polishing and thermocycling, all specimens were prepared for DYE PENETRATION and the degree of leakage was scored and analyzed using Kruskall Wallis test with p<0.05 as the level of significance.Results: The frequency of DYE PENETRATION in different groups was obtained. The most and the least scores were observed in groups 3 and 4 respectively. No statistically significant difference was observed in different methods.Conclusion: None of the methods in this study could seal the amalgam/composite-resin interface.
