Clinical evaluation of a polyacid-modified resin composite (compomer) Academic Article uri icon

abstract

  • The purpose of this study was to evaluate the clinical performance over 1 year of the proprietary polyacid-modified composite resin Dyract (DeTrey Dentsply). Forty-one restorations (five in interproximal anterior cavities, 36 in noncarious cervical cavities) were placed following the manufacturer's instructions. After 1 year, one of the cervical restorations had been lost, and eight restorations showed some degree of marginal discoloration. Overall, Dyract showed mixed results as a tooth-colored restorative material in nonstress-bearing areas. The long-term clinical performance and reasons for incipient marginal discoloration need further investigation.
