The gingival marginal discrepancies of posterior composite restorations

The purpose of this study is to assess the gingival marginal discrepancies of various types of composite restoratives using contoured matrix bands. The result of this study demonstrated that despite the great care taken during insertion and adaptation of the various composite restoratives, and inspite of bevelling of all cavosurface enamel margins, gingival deficiencies and/or excesses do still occur.
