A method and apparatus provides for treating hard deposits in body cavities. The apparatusand accordingly the methodis comprised of introducing at least one first-component comprising a material with a redox potential for preventing anions precipitation; and introducing at least one second-component comprising a material with a redox potential for preventing cations precipitation.

In a functionalization method for use in dentistry, and a method for same, the application device includes a support for receiving a partially processed shaped dental part for producing a dental restoration, and a dispensing device for the at least partial infiltration of a functionalization material onto the surface of the shaped dental part.

A biocompatible composite material for controlled release is disclosed, comprising a biocompatible metal oxide structure with a loaded network of pores. The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.

In one aspect of the present invention, a dental glass powder contains zinc, silicon, and fluorine and does not substantially contain aluminum.

An aspect of the present invention relates to a dental cement that includes a first agent including an organic peroxide and a (meth)acrylate; and a second agent including a thiourea derivative, an ascorbate, a vanadium compound, and a (meth)acrylate, where the first agent and the second agent each have a water content that is less than or equal to 1 mass %.

The present invention relates to oral care and dental implants. In particular, the present invention is a dental implant with a removable protective film that is used to prevent implant loss and remove unwanted residual cement.

Provided is a fluoroaluminosilicate glass powder that can provide a dental glass ionomer cement hardened body excellent in acid resistance, the glass powder including sodium and potassium which have an effect of lowering the reflective index of glass. A mass ratio of potassium to sodium in the component is in the range of from 1.2 to 1.9 in terms of oxide.

A dental composition comprising: a) about 1 to about 80% by weight of particulate material including: (i) calcium silicate, calcium aluminate, tetracalcium aluminoferrite, calcium phosphate, calcium sulfate, silica, alumina, calcium oxide, calcium hydroxide, or mixtures thereof; wherein the particulate material has an average particle size of less than 40 microns; and b) about 1 to about 50% by weight liquid carrier including: (i) water-soluble polymer, and (ii) water.

A temporary root canal sealer dispersion having a pH of at least 9 and comprising: (i) an aqueous dispersion medium comprising an oligomer and/or polymer having Lewis basic groups, and optionally a hydroxide of an alkali metal and/or a hydroxide of an alkaline earth metal, and (ii) a dispersed phase comprising a radio-opaque filler, wherein the weight ratio of oligomer and/or polymer having Lewis basic groups to hydroxide of an alkali metal and/or hydroxide of an alkaline earth metal is at least 0.5 when said aqueous dispersion medium comprises a hydroxide of an alkali metal and/or a hydroxide of an alkaline earth metal.

A method and apparatus, for treating plaque and calculus in the mouth cavityparticularly on teethare disclosed. The apparatusand accordingly the methodis comprised of introducing at least one first-component comprising a material with a redox potential for preventing anions precipitation; and introducing at least one second-component comprising a material with a redox potential for preventing cations precipitation.
