title: Microleakage of pin-retained amalgam and composite resin bases.
abstract: The marginal leakage of a composite resin (Adaptic) and an amalgam (Tytin) utilized as pin-retained bases was studied. The results indicated that the amalgam bases had less leakage than composite resin bases. No significant difference was found between the degree of leakage at enamel margins and dentinal margins.
