title: Influence of dentin-bonding agents and a glass-ionomer base on the cervical marginal seal of Class II composite restorations.
abstract: The cervical dentin marginal seal of Class II composite resin restorations was assessed in vitro. Elimination of marginal contraction gaps by specific dentin-bonding treatments led to a reduction in the extent of cervical microleakage as assessed by a silver staining method. The use of a "sandwich" technique employing a glass-ionomer material to seal the cervical cavity margin did not prevent cervical microleakage occurrence.
