title: The effect of finishing composite resin surfaces at different times.
abstract: 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.
