Effects of approximal finishing strips.

Abstract

The effects of a representative sample of approximal finishing strips on the surfaces of restorations, the approximal margins of restorations and on the surfaces of enamel adjacent to restorations have been evaluated using scanning electron microscopy. The results indicate that the sample of finishing strips investigated tend to damage the surface of enamel and fail to leave restorations with either ideal surface finish or marginal adaptation. Guidelines are suggested for the choice of approximal finishing strips in selected clinical situations.
