title: [Marginal defects in amalgam fillings after the use of 2 intermediate substances].
abstract: Thirty-six Class V amalgam restorations were placed in 29 patients. Prior to insertion of the amalgam in 12 cavities the walls were treated with Amalgam Liner and in another 12 cavities with Copalite. The remaining 12 cavities were not treated before amalgam insertion. The margin quality was determined quantitatively with the SEM using replicas obtained immediately after the polishing of the restorations and 6 months later. At baseline the cavities treated with Copalite showed a margin quality identical to the untreated cavities. Cavities treated with Amalgam Liner showed an inferior margin quality. After 6 months the margin quality of the three groups showed no statistical differences. With neither of the liners tested was it possible to improve the margin quality of amalgam restorations.
