    摘要: The present invention provides a paste-form two-pack type dental curable composition having an adequate working time range and superior bond strength to dentin, in addition to showing small variation in working time, small decline in bond strength to dentin, and low risk of paste solidification over extended storage. The present invention relates to a paste-form two-pack type dental curable composition comprising: a first agent that comprises an acidic group-containing polymerizable monomer (A), an acidic group-free polymerizable monomer (B), an organic peroxide (C), a nitrogen atom-containing ligand (D), and a filler (E); and a second agent that comprises an acidic group-free polymerizable monomer (B), a thiourea compound (F), and a filler (E).
