Abstract
A dental composition comprising a pre-reacted particulate mineral trioxide aggregate (MTA) dispersed in a polymer matrix wherein the content of MTA in the composition is in the range of 20 to 50 percent by weight based on the total weight of the composition.
Claims11
A dental composition comprising a pre-reacted particulate of cured mineral trioxide aggregate (MTA) dispersed in a non-aqueous polymer matrix, wherein the content of cured particulate MTA is in the range of 20 to 50 by weight based on the total weight of the composition and wherein the pre-reacted particulate of cured MTA has an average particle size of from 0.1 to 100 microns;
- wherein the non-aqueous polymer matrix includes a silicone polymer or a polymerizable material selected from methacrylated polyisoprene, epoxy modified liquid polyisoprene or amine modified liquid polyisoprene.
A process for the preparation of a dental composition comprising the steps of:
- (i) providing a cured mineral trioxide aggregate MTA;
- (ii) milling the cured MTA to an average particle size of from 0.1 to 100 microns to form a pre-reacted particulate of cured MTA;
- (iii) dispersing the pre-reacted particulate of cured MTA in a non-aqueous polymer matrix for forming a composite composition;
- wherein the non-aqueous polymer matrix includes a silicone polymer or a polymerizable material selected from methacrylated polyisoprene, epoxy modified liquid polyisoprene or amine modified liquid polyisoprene.
