This invention relates to a hardening material for medical and dental use, in which at least either one of α-tricalcium phosphate and/or tetracalcium phosphate is an essential component. n Since the hitherto-known hardening material for medical and dental use, in which α-tricalcium phosphate and/or tetracalcium phosphate are essential components, have used an aqueous solution of one kind of organic acid as a setting solution, it was difficult to safisfy working efficiency for kneading as well as time necessary for hardening. Thus, the subject of this invention is to provide a hardening material for medical and dental use by which the working efficiency for kneading and the time necessary for hardening are satisfied. n To solve said subject, the hardening material for medical and dental use relating to this invention involves, as a hardening adjuster, use of the following: (a) tannin and an organic acid, or (b) at least two kinds of organic acids. |
