Disclosed is a dental curable composition whose curing time is from 30 seconds to 120 minutes. This dental curable composition is characterized by containing 0.01-80 parts by weight of a compound (A) having an acidic group in a molecule, 21-99.8 parts by weight of a polymerizable monomer (B), 0.01-30 parts by weight of an organic amine compound (C), and 0-30 parts by weight of a sulfur-containing reducing compound (D). (In this connection, the total of the components (A)-(D) is taken as 100 parts by weight. When there is a compound falling under the categories of two or more of the components (A)- (D), the parts by weight of such a compound is divided by the number of the corresponding components and the quotient is taken as the content of respective components.) The dental curable composition can be cured in a comparatively low temperature range near body temperature without using a peroxide polymerization initiator, while exhibiting good sealing property and good adhesion.

L'invention concerne une composition vulcanisable dentaire dont le temps de cuisson est compris entre 30 secondes et 120 minutes. Cette composition vulcanisable dentaire est caractérisée en ce qu'elle contient de 0,01 à 80 parties en poids d'un compound (A) ayant un groupe acidifère dans une molécule, de 21 à 99,8 parties en poids d'un monomère polymérisable (B), de 0,01 à 30 parties en poids d'un composé aminé organique (C), et de 0 à 30 parties en poids d'un composé de réduction contenant du soufre (D). (Dans cette perspective, le total des composants (A)-(D) est considéré comme de 100 parties en poids. Si un composé entre dans la catégorie de deux ou plusieurs des composants (A)-(D), les parties en poids d'un tel composé sont divisées par le nombre de composants correspondant et le quotient est pris comme la teneur des composants respectifs.) La composition vulcanisable dentaire peut être cuite dans une fourchette de température comparativement basse proche de la température corps sans utiliser d'initiateur de polymérisation de peroxyde, tout en présentant une bonne propriété d'étanchéité et une bonne adhérence.
