摘要： A composition for use as a dental impression material including a polymerizable telechelic oligomer or polymer curable by ring-opening metathesis polymerization, a filler system, and a ruthenium carbene complex catalyst, whereby the catalyst initiates ring-opening metathesis polymerization of the composition. The invention includes a paste/paste system in which a base paste includes the polymerizable telechelic oligomer or polymer and a filler system and in which a catalyst paste includes the catalyst dissolved in an inert solvent and a filler system. The telechelic oligomer or polymer may be, for example, a polydimethylsiloxane end-functionalized with norbornenyl groups. The catalyst may be, for example, a ruthenium carbene complex with a ligand having a basicity higher than tricyclohexylphosphine. The composition of the present invention exhibits reduced sensitivity to sulfur impurities.

摘要： Compositions for conditioning a tooth surface prior to the application of a dental materials which will desirably form a substantially permanent bond with the conditioned tooth surface are provided. The conditioning compositions comprise an amount of an essential oil effective to alter the sensory properties, i.e. the taste, a smell, of the conditioning composition and that desirably imparts a more pleasing taste and/or odor. Also provided are methods of using the conditioning composition to prepare a tooth surface for the application of a free radically polymerizable dental material and for treating a tooth by forming a substantially permanent bond with a free radically polymerizable dental material.

摘要： Compositions, method and systems for bleaching tooth surfaces in an accelerated manner. The dental bleaching compositions include a bleaching agent and a stable radiant energy absorbing material that acts as a bleaching agent activator. The dental bleaching compositions of the present invention can be stable one-part compositions that do not require mixing at the time of treating a person's teeth but which remain stable over time. The dental bleaching composition is applied to the labial surface of teeth that are to be bleached. A source of radiant energy is directed onto the treated tooth surfaces to accelerate bleaching activity. The radiant energy source includes a dental light guide having an arcuate light directing member that is positioned in close proximity to the treated teeth. The light directing member has one or more light-emitting panels communicating with a radiant energy generating source that efficiently direct radiant energy onto the treated tooth surfaces. The dental light guide can irradiate all treated teeth of one or both dental arches simultaneously while in a fixed position relative to the one or both dental arches. The inventive dental compositions may also be activated using, e.g., conventional curing lights and lasers.

摘要： Composition and methods that include potassium nitrate for whitening and/or reducing tooth sensitivity. The dental compositions may optionally include a dental bleaching agent, such as hydrogen peroxide or carbamide peroxide. The dental compositions may be applied directly to the person's teeth, or they may be loaded into a comfortable fitting, flexible, thin-walled dental tray and placed over the person's teeth. In that case, the dental compositions will include a tackifying agent, such as carboxypolymethylene, dispersed within a solvent, which assists the composition in retaining the dental tray over the person's teeth as a result of the adhesive properties of the dental composition rather than due to mechanical interlocking of the tray over the person's teeth. The dental compositions may further include anticariogenic and antimicrobial agents.

摘要： A process and composition for bleaching teeth made up of two formulations blended together before each application. The invention offers faster results while significantly reducing the possibility of user discomfort. One of said formulations contains hydrogen peroxide (in a free form or in the form of an adduct), the other contains salts and hydroxides and/or oxides of metals belonging to the first or second group of the Periodic Table which stimulate the generation of radical oxygen. The invention allows for balancing pH and assuring adequate water concentration to avoid tissue desiccation and user discomfort without compromising shelf life of the device.
