摘要:
Thermally responsive compositions that include a thermally responsive viscosity modifier, a polymerizable component, and water are provided. The compositions, which optionally may be hardened, are useful for application to a surface of a body.
摘要:
Methods and compositions including an aqueous liquid that includes an acid-sensitive dye are disclosed for use in dental and orthodontic procedures. The aqueous liquid can be useful for providing a visible color change to indicate contact with acidic materials including, for example, etching compositions, self-etching adhesives, and self-adhesive compositions.

The abstract has been amended as follows: A method of dispensing a hardenable dental composition, which can form a temporary bond, comprising 1) providing multi-part hardenable dental composition comprising part (A) in the form of a paste comprising acid-reactive glass particles and a liquid selected from the group consisting of water, a monomer having at least one ethylenically 10 unsaturated group per monomer molecule, and a combination thereof; and part (B) comprising a water soluble polyacid and a liquid selected from the group consisting of water, a monomer having at least one ethylenically unsaturated group per monomer molecule, and a combination thereof; and 2) extruding the composition through a static mixer in fluid communication with a first reservoir containing the part (A) and a second reservoir 20 containing the part (B); wherein a plunger is positioned in each reservoir for simultaneously forcing part (A) and part (B) into the static mixer.
摘要:
This invention relates to polymerizable compositions comprising a salt of a barbituric acid derivative. The compositions are typically shelf-life stable and may be polymerized through mixing of an acidic component with the salt of a barbituric acid derivative.

The abrasive particle having an average diameter of less than about 200 micrometer.
摘要:
The present invention features ionomer compositions containing nanozirconia fillers. The compositions can be used in a variety of dental and orthodontic applications, for example, as adhesives, cements, restoratives, coatings and sealants.
摘要:
The present invention is directed to dental compositions that can be used as adhesives for bonding a dental material to a dental structure surface and/or as a dental restorative material. The dental composition is preferably applied to a dental structure surface under conditions effective to etch the dental structure surface.

摘要:
The invention features a photopolymerizable composition that comprises a cationically polymerizable resin, and a photoinitiator system comprising an iodonium salt, a visible light sensitizer, and one or more anthracene-based compounds as electron donors. Electron donor combinations used in the invention include multiple substituted anthracene compounds or a combination of at least one substituted anthracene compound with unsubstituted anthracene.
摘要:
Polymerizable compositions that include: (a) a cationically active functional group; (b) an initiation system capable of initiating cationic polymerization of the cationically active functional group; and (c) a filler composition that includes various radiopacifying fillers in an amount sufficient to render the polymerizable composition radiopaque. Components (a), (b), and (c) are selected such that the polymerizable composition polymerizes to form a polymerized composition having a Barcol hardness, measured using a GYZJ-935 meter, of at least 10 within 30 minutes following initiation of the cationically active functional group at a reaction temperature of 25° C.
