A dental device is improved in its ability to produce hydroxyl apatite by having a layer of mineral trioxide aggregate (MTA) deposited thereon. A tile of MTA is prepared, heat treated and sintered to produce a micronized tile of MTA that can then be deposited by physical vapor depositions, hot isostatic pressing, molding or other conventional technique.

A method of direct pulp capping of a tooth including administering a dental composition comprising betamethasone and gentamicin onto an exposed pulp of a tooth, and covering the dental composition present on the tooth with a glass ionomer cement. The dental composition is administered in an amount effective to form a calcification over the exposed pulp. A dental composition having betamethasone, gentamicin, and optionally including a Portland cement. The dental composition is administered to an exposed pulp of a tooth to form a calcification over the exposed pulp.

Compositions of, methods of making, and methods of using alkaline earth phosphate bone cements are disclosed.

According to one aspect of the present disclosure, there is provided a single paste type hydraulic dental filling composition. The single paste type hydraulic dental filling composition includes hydraulic cement, non-aqueous liquid having hygroscopic properties, and a radiopaque material.

A dental composition comprising pre-reacted particulate mineral trioxide aggregate (MTA) dispersed in a hydrogel 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.

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.

The present invention generally relates to the use of pre-formed bodies of Chemically Bonded Ceramics (CBCs) biomaterial for implantation purposes wherein the bodies are prepared ex vivo allowing process parameters to be optimized for desired long term properties of the resulting CBC biomaterial. More particularly, the pre-formed CBC material bodies of the present invention are sintered. The pre-formed body of CBC material is machined to the desired geometry and then implanted using a CBC cementation paste for fixation of the body to tissue. The invention also relates to a method of preparing pre-formed bodies of CBC biomaterial for implantation purposes, methods of preparing an implant thereof having desired geometry, and a method of implantation of the implant, as well as a kit for use in the method of implantation.
