Abstract: Disclosed herein are dental temporary filling material and cement formulations comprising a hydrophobic matrix of a hydrophobic material in which an inorganic hardening material and fine, hydrophilic, water-insoluble solid particles are dispersed. The hydrophilic particles serve to conduct water into the hydrophobic matrix to increase the depth and degree of cure in the oral environment as compared to a similar or substantially identical formulation lacking said hydrophilic component.

Abstract: Disclosed herein are acrylic and methacrylic acid ester-based polymeric materials containing as flexibilizing and brittleness reducing agents 1-60% of C4-C8 polyalkylene or polyalkyldiene compounds, preferably having a molecular weight of 300-2100, and the use of such materials in dentistry and medicine.

Abstract: Disclosed are dental varnishes comprising reaction products of rosins with polyalcohols dissolved in mixtures of C2-C4 alcohols with C5-C7 hydrocarbons or C5-C7 hydrocarbons alone which have been found effective in preventing tooth decay and alleviating tooth sensitivity. Such varnishes may, optionally, incorporate therapeutic, antimicrobial and sensory enhancing ingredients.

Abstract: At least one shock-sensitive device is mounted within an enclosure using a shock-absorbing element as an exclusive point of contact between the shock-sensitive device and the enclosure. The shock-sensitive device may comprise a disk drive and/or a printed circuit board. The enclosure may comprise an end cap having at least one mounting bracket or flange to receive the shock-absorbing element. The shock-sensitive device may comprise a mounting tab to receive a fastener, wherein one end of the fastener is received in the mounting tab, and wherein the other end of the fastener is received in the shock-absorbing element. The shock-absorbing element may comprise a resilient material such as rubber, silicone, urethane, or foam. In an embodiment, the end cap may include ventilation holes.

Abstract: Disclosed are dental varnishes comprising hydrogenated wood rosin and/or gum rosin dissolved in C2-C4 alcohols, C5-C7 hydrocarbons, or mixtures thereof, for use in preventing tooth decay and/or alleviating tooth sensitivity. Such varnishes may, optionally, incorporate therapeutic, antimicrobial and sensory enhancing ingredients.

Abstract: Disclosed is a novel glass ionomer type dental cement composition comprising a first component comprising an aqueous solution of polymers made from monomers comprising acrylic acid, and a second, preferably substantially anhydrous, component comprising alkaline glass flux in a medium comprising water soluble/miscible monomers or pre-polymers, of such monomers, having at least one —OH group per molecule. The compositions offer more convenient handling, excellent reproducibility of desired properties of the cured material, improved strength, and extended shelf life.

Abstract: Disclosed is a process and composition for bleaching teeth made up of two components blended together before each application. The method and composition offers faster results while significantly reducing the possibility of user discomfort. One of said components comprises carbamide peroxide, 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. In one embodiment, the first part comprises up to 50% water by weight and optionally comprises a stabilizer. In some embodiments, the first component is substantially colorless and the second component comprises a dye indicator which discolors or loses color when exposed to radical oxygen generated by the mixing of the two components.

Abstract: Securing a dental post or a crown or bridge onto the dentin portion of a prepared tooth by utilizing a no-mix, two component, self-curing cement wherein the first component of the cement is applied to the interior dentin surfaces of a post hole, or onto the dentin surface of the tooth receiving the crown or bridge, and applying the second component of the cement onto the surface of a post, or crown or bridge so that when the post or crown or bridge is fitted onto the exposed dentin of a prepared tooth, the complementary components of the cement immediately chemically set to firmly secure the post, crown or bridge onto the prepared tooth. The respective components of the no-mix, two component, self-curing cement formulation for practicing the method require that each include a methacrylate resin. One of the components also includes an aromatic tertiary amine and the other component includes an organic peroxide.

Abstract: Disclosed are compositions for bleaching teeth, comprising a single component part or two or more components blended together before each application. The compositions offer extended shelf life and accelerated bleaching action while significantly reducing the possibility of user discomfort. In preferred embodiments, the composition or one of its parts comprises a blend of hydrogen peroxide and carbamide peroxide in a solution having the consistency of a gel or a viscous liquid. The inventive system allows for water in the composition to avoid tissue desiccation and associated user discomfort, without compromising the shelf life of the composition.

Abstract: Described herein is a novel teeth whitening chewing gum formulation comprising bivalent metal peroxide(s) and anhydrous organic acids. Upon mastication in the oral environment, the acids react with the peroxide to form hydrogen peroxide in situ, in an environment stimulating the decomposition of such peroxide to form water and radical oxygen. The system is characterized by its efficacy and convenience. The teeth whitening composition of the preferred embodiment is also virtually insensitive to storage conditions, allowing for an extended shelf life.

Abstract: A method of securing a dental post in a prepared post hole of a tooth or a crown or bridge to a prepared tooth utilizing a no-mix, two component, self-curing cement wherein the first component is applied with a micro sized applicator to coat the interior surfaces of a post hole, crown or bridge, and wherein the second component is thereafter placed into the coated post hole or onto the surface of the tooth receiving the crown or bridge, and whereby the post, crown or bridge is then fitted onto the prepared tooth. Upon fitting of the post, crown or bridge, the components immediately set to firmly secure the post, crown or bridge onto the prepared tooth.

Abstract: Described herein is a novel high efficiency teeth bleaching system based on thesynergetic action of the combination of hydrogen peroxide (in a free form or in the form of its adduct with urea) and peroxide and/or percarbonates of metals belonging to the first or second group of the periodic table. In one embodiment, the system of the preferred embodiment comprises two components, one containing hydrogen peroxide or carbamide peroxide (hydrogen peroxide/urea adduct), and the other containing metal peroxides and/or percarbonates. Mixing of the two components results in the accelerated generation of radical oxygen, which relates to faster teeth bleaching action.
