To provide a liquid for improving translucency for dental zirconia calcined body which may impart high translucency which is similar to an enamel of a natural tooth to a zirconia sintered body and a method for using thereof.

The liquid for improving translucency for dental zirconia calcined body of the present disclosure contains a solvent and an indium compound, wherein a content of the indium compound based on the total amount of the liquid improving translucency for dental zirconia calcined body is within a range of 2.0 wt. % to 20.0 wt. % in terms of indium.

[Problem]

A technique for imparting high translucency which is similar to an enamel of a natural tooth to a zirconia sintered body, has been required.

[Solution]

To provide a zirconia mill blank for dental cutting and machining, containing, an yttrium compound and an indium compound as stabilizers, wherein, an amount of the yttrium compound is within a range of 3.0 mol % to 6.0 mol % in terms of oxide, an amount of the indium compound is within a range of 0.2 mol % to 3.0 mol % in terms of oxide, and a total amount of the yttrium compound and the indium compound is within a range of 5.5 mol % to 7.0 mol % in terms of oxide.

Provided herein are compositions and their methods of use to adhere (e.g., in wet and dry environments) a variety of materials together.

The present invention provides novel multi-functional (e.g., repelling biofilms, promoting formation of minerals, and having anti-infection properties) biocomposites and methods of use thereof. In various embodiments, the present invention also provides method for simultaneously treating biofilms, promoting mineralization, treating infection, or any combination thereof.

The present invention relates to a composition of an intracanal medication agent for medicating root canals for a predetermined period of time. According to one aspect of the invention, there is provided an intracanal medication composition based on a calcium hydroxide component, comprising: calcium hydroxide or a calcium hydroxide producing component as a powder component; and at least one of diethyl sulfoxide (DMSO), N-methyl-2-pyrrolidone (NMP) and diethylene glycol monoethyl ether (DEGEE) as a liquid component.

A method for enhancing optical properties of sintered, zirconia ceramic bodies and zirconia ceramic dental restorations is provided. The porous or pre-sintered stage of a ceramic body is treated with two different yttrium-containing compositions and sintered, resulting in sintered ceramic bodies having enhanced optical properties. The enhanced optical properties may be substantially permanent, remaining for the useful life of the sintered ceramic body.

Provided is a method for producing a calcium carbonate sintered body whereby a good sintered body can be obtained without having to use any sintering aid. A method for producing a calcium carbonate sintered body includes the steps of: compacting calcium carbonate to make a green body; heating the green body under a condition of a temperature of 500° C. or lower to remove an organic component contained in the green body; and sintering the green body under conditions of a carbon dioxide atmosphere and a temperature of 450° C. or higher to obtain a calcium carbonate sintered body.

The present invention relates to a synthetic mineral composition. The present invention also relates to a method of forming a synthetic mineral composition. The present invention also relates to uses of a synthetic mineral composition.

The present invention relates to a glass-ceramic material. The present invention also relates to a method of forming a glass-ceramic material. The present invention also relates to uses of a glass-ceramic material.

An object of the present invention is to provide a dental resin-reinforced glass ionomer cement composition which exhibit high surface curability even under wet conditions, which makes it difficult for the surface to become cloudy even if moisture comes in contact with at the initial stage of curing, exhibits high mechanical properties, low water absorption expansion and excellent coloring resistance in the set product and is also excellent in storage stability. The dental resin-reinforced glass ionomer cement composition consisting of a powder material and a liquid material, wherein the powder material contains (a) acid-reactive glass powder, the liquid material contains (b) water, (c) polymer of acidic group-containing polymerizable monomer, (d) hydroxyl group-containing (meth)acrylate-based polymerizable monomer and (e) tri or more functional (meth)acrylamide-based polymerizable monomer, and at least one of the powder material and the liquid material contains (f) polymerization initiator.
