A 5-year study comparing a posterior composite resin and an amalgam.

Eighty class I and class II light-cured posterior composite resin restorations were compared with 43 class I and class II amalgam restorations during a 5-year period after placement. The results of this clinical study showed that both materials were satisfactory during the time period and that the only significant statistical differences are a poorer marginal integrity for the amalgam and a greater wear rate for the composite resin.

The effect of finishing composite resin surfaces at different times.

This study was designed to compare the surface smoothness of two composite resins finished at different time intervals. The results indicate that the surfaces of the composite resins are unquestionably smoother when polymerized against a matrix. However, when finishing procedures are needed, none of the time intervals tested in this study produced a smoother surface. This investigation demonstrates that smoothness of composite resin after finishing is not a function of the time at which it is finished.
