Abstract
The present invention provides a dental resin cement which is excellent in a mechanical strength, workability and storage stability, and a dental primer which significantly improves adhesiveness of the dental resin cement both to enamel and dentin of a tooth. According to the present invention, a salt of barbituric acid is used as a polymerization initiator in the dual-cure two-paste type dental resin cement being excellent in workability and storage stability to improve the storage stability, and a primer containing barbituric acid and amine is applied to a surface of a tooth to significantly improve adhesiveness of the dental resin cement both to enamel and dentin of teeth.
