title: Marginal penetration of composite resin restorations as indicated by a tracer dye.
abstract: There was no evidence of marginal penetration of a tracer dye around Class V preparations lined with a BIS-GMA sealant, filled with Nuva-fil (a composite restorative material), and covered with the sealant. In the control group, 72 per cent of the Adaptic restorations showed varying degrees of marginal penetration.
