Abstract:
Compositions and methods for priming or sealing dental or biological substrates for subsequent bonding. The primer is particularly useful for priming dentin of a tooth to prepare the dentin for bonding with a resinous material. The primer comprises a mixture of a polymerization initiator such as camphoroquinone and a polymerizable promoter such as methacrylic acid. Polymerizable promoters within the scope of the present invention have at least one ethylenically unsaturated group and at least one carboxylic acid group. The primer may further comprise a solvent such as ethanol, a natural resin such as Canadian balsam and a polymerizable resin such as 2-hydroxyethyl methacrylate (HEMA). The primer can also be formed from a mixture of a polymerization initiator, a natural resin and a polymerizable resin.
