Clinical evaluation of a polyacid-modified resin composite (Dyract) in class V carious lesions: 5-year results.

Abstract

This study evaluated the 5-year clinical performance of polyacid-modified resin composite, Dyract (DeTrey/Dentsply, Konstanz, Germany), restorations in class V carious lesions. Ninety-two class V carious lesions in 28 patients were restored with Dyract. Restorations were clinically evaluated at baseline, 1-, 2-, 3-, 4-, and 5-year recalls and were evaluated according to the modified Ryge criteria by two experienced calibrated examiners in regard to color match, marginal discoloration, wear or loss of anatomical form, caries, marginal adaptation, and surface texture. The retention rate after 5 years compared to baseline in class V carious restorations was 84%, with only 12 restorations failing. Color change and marginal discoloration in restorations were found to be statistically significant (p = 0.0238 and p < 0.0001, respectively) at the end of the 5 years, but did not require replacement of any of the restorations. The results of this study revealed that at the end of 5 years, Dyract exhibited a clinically acceptable success rate but had significant color changes and marginal discoloration in class V carious lesions.
