PROBLEM TO BE SOLVED: To obtain a curing composition capable of being adhered to a tooth, especially a dentine, with no gap by simple adhering operation even under a damp or wet condition, and further to obtain a curing composition having adhesive properties to a dentine without an acid etching or a primer treatment and a high viscosity of the curing composition itself to generate no gaps in the adhered interface and capable of adhering by simple operation. SOLUTION: This curing composition capable of being adhered to an in vivo hard tissue without gap is either one of three compositions; a first curing composition comprising a polymer containing sulfonic acid groups in the molecule, a polymerizable monomer containing hydroxyl groups in the molecule and an initiator, a second curing composition prepared by adding a polymerizable monomer capable of copolymerizing with the aforesaid polymerizable monomer containing hydroxyl groups in the molecule or a third curing composition prepared by adding at least one kind of additive selected from an organic filler, an inorganic filler and an organic composite filler to the first or second curing composition. |
