An adhesion promoter for endodontic sealant compositions for filling and sealing a root canal.

The present invention provides a dental curable composition and a dental prosthesis therewith with which shade changes in the base material can be reduced, and that exhibit excellent gloss retention in the cured product while demonstrating excellence in operability. The present invention relates to a dental curable composition comprising a polymerizable compound (A), a polyfunctional thiol (B) having two or more mercapto groups per molecule, a polysiloxane (C), and a polymerization initiator (D).

A dental composition for the desensitization and covering of an area of a human tooth comprising a finger malleable base material made up of a product consisting of either: one or more hydrocarbon-based waxes, possibly with either or both of an organic filler and an inorganic filler, an uncured, uncross linked silicone high consistency rubber base; or a hydrophobic water insoluble solid material that is malleable at 37 C. or lower and safe for a human oral environment. The dental composition also includes a combination of dry, powdered materials dispersed on a tooth-engaging surface of the finger malleable base material. The combination of dry, powdered materials comprises a water-soluble polymeric adhesive and at least one dental tubule blocking agent or hypersensitivity desensitization ingredient.

A radically polymerizable composition including at least one urethane group-containing (meth) acrylate monomer, at least one fracture toughness modifier and at least one transfer reagent of the general formula I

##STR00001##

The composition is particularly suitable as dental materials, for example for the production of dental moldings by generative processes, and is characterised by a high fracture toughness.

The present invention provides a dental composition that exhibits excellent storage stability even under severe conditions, and shows sufficient mechanical strength in its cured product. The invention also provides a method of production of such dental compositions, and surface-treated fillers for dental use. The present invention relates to a dental composition comprising a polymerizable monomer (A), a polymerization initiator (B), and a filler (C), wherein the filler (C) comprises a surface-treated filler for dental use (C-1) surface-treated with a silane coupling agent (a) having a polymerizable group, and an end capping agent (b), and the surface-treated filler for dental use (C-1) shows a dissolution rate of less than 100 ppm for metallic components in an acid resistance test.

The present disclosure is generally directed toward a pontic material that is pliable and easily moldable, possesses a higher tear resistance to resist fragmenting and thus is long lasting, can be pigmented to achieve a good color match to adjacent teeth, and be fashioned into a pontic by the patient at home so as to free the orthodontist and their staff from having to do this purely aesthetic and time-consuming procedure. In addition, the pontic material of the present disclosure is typically permanently pliable so that an untrained person such as a patient would have unlimited time to make corrections to the shape of the material to obtain an aesthetically pleasing shape and typically do so without the use of tools or any specialized tools or equipment.
