Description

ABSTRACT:
A primer composition for the treatment of a tooth surface, which comprises a) at least one metal compound selected from the group consisting of an iron compound, a copper compound and a cobalt compound, b) a polymerizable monomer having an acidic group, and c) water or water and an organic solvent miscible with water; and a method of forming an adhesive layer on a tooth surface, which comprises applying this primer composition to the tooth surface and then applying a curable composition containing trialkylborane or partial oxide thereof and a polymerizable monomer. According to the present invention, both the enamel and the dentin of a tooth can be simultaneously surface-treated without acid treatment or washing with water, and adhesion dental treatment can be reliably carried out by a simple operation without causing pains on a patient.
