A method for masking the appearance of a support structure underlying a highly translucent ceramic dental restoration is provided. The porous form of a zirconia ceramic dental restoration is treated with a liquid masking composition comprising 0.4 wt % to 50 wt % of one or more masking agents. The masking composition is applied to the internal surface of a restoration and a region of the facial surface of the restoration that is opposite the internal surface. After application of the masking compositions, treated zirconia restoration is sintered to greater than 98% theoretical density.

According to one aspect of the present disclosure, there is provided a single paste type hydraulic dental filling composition. The single paste type hydraulic dental filling composition includes hydraulic cement, non-aqueous liquid having hygroscopic properties, and a radiopaque material.

The disclosure provides biocompatible dental material that is moldable and biodegradable and provides sustained and/or controlled delivery of one or more local anesthetics within a dental cavity or space. Such dental material is customizable for the size and shape needed for a particular patient or particular application. The dental material may also provide customizable sustained and/or controlled delivery of one or more local anesthetics.

The present invention provides a dental adhesive kit whereby a separate-pack type dental adhesive composition exhibits excellent bond durability with respect to the surface of a one-pack type self-adhesive dental composite resin coating a prepared tooth surface. The present invention relates to a dental adhesive kit comprising: a one-pack type self-adhesive dental composite resin (X) that comprises a monomer (a-1) having a divalent phosphoric acid group with a backbone C8 to C16 alkyl or alkylene group within the molecule, a monomer (b) having no acidic group, a photopolymerization initiator (c), and a filler (d); and a separate-pack type dental adhesive composition (Y) that comprises a first agent and a second agent that are separately packed from each other, with the first agent comprising a monomer (a) having an acidic group, and a chemical polymerization initiator (e), and the second agent comprising a monomer (b) having no acidic group, wherein a cured product of the self-adhesive dental composite resin (X) after light curing has a flexural modulus ranging from 1.5 to 6 GPa, and a cured product of the separate-pack type dental adhesive composition (Y) after chemical curing has a flexural modulus ranging from 1.5 to 6 GPa.

A pharmaceutical formulation for topical dental administration or medical (e.g., implant) treatment, including effective amounts of: at least one antimicrobial compound; at least one peroxide source compound; and at least one gel agent. Also disclosed are methods of oral anatomy treatment. The pharmaceutical formulation and treatment methods provide the patient with oral anatomy benefits including, for example, decreased or arrested gum recession; decreased or arrested bone recession; decreased or arrested bone mass loss; decreased or eliminated pain; decreased or eliminated bleeding; decreased or eliminated swelling; enhanced regeneration of bone; enhanced soft tissue repair; or a combination thereof.

The invention relates to a coloring solution for coloring a dental ceramic article, the solution comprising: a solvent and a coloring agent, comprising rare earth element metals or ions being present in the solution in an amount of at least about 0.05 mol/1 solvent and transition metals or ions being present in the solution in an amount of about 0.00001 to about 0.05 mol/1 solvent. The invention also relates to a process for coloring dental ceramic articles, dental ceramic articles treated either with the coloring solution or obtainable by a process comprising the step of firing the dental ceramic articles.

Aerogel, calcined articles, and crystalline articles comprising ZrO.sub.2. Exemplary uses of the crystalline metal oxide articles include dental articles (e.g., restoratives, replacements, inlays, onlays, veneers, full and partial crowns, bridges, implants, implant abutments, copings, anterior fillings, posterior fillings, and cavity liner, and bridge frameworks) and orthodontic appliances (e.g., brackets, buccal tubes, cleats, and buttons).

Dental cement compositions (including two-part compositions), kits, and related methods are used for bonding a dental prosthetic appliance to a tooth. A first part includes an amine activator component and a zinc oxide reactive filler, while a second part includes a polymerization initiator (e.g., benzoyl peroxide) and a polymerizable component having a structure including at least one acrylate or methacrylate group at one end and a carboxylic acid group at another end. A temporary cement composition advantageously exhibits reduced compressive and/or bonding strength relative to permanent cement compositions, which provides sufficient strength to facilitate normal use of the teeth while the provisional appliance is in use, while also facilitating easy removal of the provisional appliance for replacement with a permanent appliance at a later time.
