Influence of dentin-bonding agents and a glass-ionomer base on the cervical marginal seal of Class II composite restorations.
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.
