The invention relates to fine and uniform copolymer powders of partial mixed metal salts of lower alkyl vinyl ether-maleic acid copolymers having a defined particle size distribution. In particular; it relates to powders that are suitably used in the areas of oral care and pharmaceuticals and to methods for preparing the powders. Provided is a composition of powders of partial mixed metal salts of lower alkyl vinyl ether-maleic acid copolymers having: (i) a Dv50 of less than or equal to 25 microns; a Dv90 of less than or equal to 50 microns; and (ii) a particle uniformity reflected by a Dv90/Dv10 ratio of less than or equal to 10.

The invention relates to a kit of parts for preparing a glass ionomer composition for dental use, the kit comprising a Paste A and a Paste B, Paste A comprising water, acid-reactive inorganic filler A, phyllo silicate(s), Paste B comprising water, poly-acid, non acid-reactive filler B, optionally chelating agent. The invention also relates to a hardenable composition obtainable by combining the pastes of the kit or parts and to the use of such a composition as or for preparing a dental cement, dental filling mater ial, dental core build up material or dental root channel filling material.

The invention relates to a curable dental retraction composition comprising alginate and a solvent, with the proviso that essentially no crosslinker in an amount effective to start setting of the curable dental retraction composition is present. The invention also relates to a container containing said composition and to a kit comprising two parts, wherein the first part comprises the curable dental retraction composition of the present invention and the second part comprises a crosslinker being able to start setting of the dental retraction composition.

A bone-repairing agent excellent in workability and applicability to clinical surgical techniques and having a drastically enhanced bone formation rate, obtained by including an elastin hydrolysate in a complex of DNA and at least one selected from the group consisting of protamine, a protamine derivative, and a protamine hydrolysate can be provided. A medical or dental material for bone formation using this bone-repairing agent can be provided.

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

Addresses the invention of product comprising: metal particles and/or free or complexed metal ions; fluoride; organic acid and polysaccharides, with or without additives, designed to prevent the occurrence of tooth lesions caused by dental caries, interrupt the development of such lesions, and to promote the remineralization of the affected teeth and a process of obtaining this product.

Cellulose cyanoacrylate is employed to bond two surfaces, fill voids or duplicate the shape of a three-dimensional object, Two surfaces may be bonded by placing a sheet of cellulose material between the surfaces and applying cyanoacrylate glue around the edge of the sheet until saturated and allowing it to cure. Paper toweling may favorably be employed as the cellulose material. A break or fracture in an article can be overlaid with a sheet of cellulose that when saturated with cyanoacrylate glue and temporarily held in place and shaped with a releasable film, the fracture can be corrected. A dry powder comprising highly abrasion-resistant particles can be mixed with the cellulose material to enhance abrasion resistance and to improve long-term color stabilityespecially important for dental cavity treatment. To duplicate the shape of a three-dimensional object, a sheet of releasable film is placed over the object, followed by a sheet of cellulose that is then saturated with cyanoacrylate glue. A sheet of releasable film is then placed over the cellulose and used to hold the cellulose in place and shape it as it hardens.
