Title

MICROLEAKAGE OF CLASS II COMBINED AMALGAM-COMPOSITE RESTORATIONS USING DIFFERENT COMPOSITES AND BONDING AGENTS

Pages

  126-130

Abstract

 Objective: The purpose of the present study was to assess the microleakage of composite restorations with and without a cervical amalgam base and to compare the results of different composites and bonding agents. Materials and Methods: One hundred and twenty mesioocclusal (MO) and distoocclusal (DO) Class II cavities were prepared on sixty extracted permanent premolar teeth. The teeth were randomly divided into four groups of 30 and restored as follows: In group A, the mesioocclusal cavity (MO), Scotchbond multi purpose plus + Z250 and in the distoocclusal (DO) cavity, Prompt-L-Pop + Z250 were applied. As for group B, in the MO and DO cavities, Clearfil SE Bond + Clearfil APX, and varnish + amalgam (In box) + Clearfil SE Bond + Clearfil APX were used respectively while in group C; the teeth were restored with amalgam and varnish mesioocclusally and with amalgam only distoocclusally. As for group D, varnish + amalgam (in box) + Scotchbond multipurpose plus + Z250 were applied mesioocclusally and Varnish + Amalgam (in box) + Prompt–L–Pop + Z250 distoocclusally. Marginal leakage was assessed by the degree of dye penetration into various sections of the restored teeth. Chi-square and Fish-er's exact tests were used for data analysis. Results: Microleakage in gingival margin was more than that in occlusal margin (P<0.05) and microleakage of combined amalgam composite restorations was significantly lower than that of conventional composite and amalgam restorations. Conclusion: Marginal microleakage decreased by using amalgam at the base of the box in Class II composite restorations.
