Abstract: Improved compositions comprising a mixture of particulate materials with water-based liquids containing water-soluble polymers and surfactants are provided. Examples of particulate powders include mixtures of calcium silicate, calcium aluminate, calcium sulfate, and hydroxyapatite. Examples of water-soluble polymers include polyvinyl alcohols, polyvinyl pyrrolidone, partially hydrolyzed polyvinyl acetates, polyacrylic acid, and polymethacrylic acid. Surfactants such as sodium dodecyl sulfate are added to the composition to interact with the polymeric materials. The compositions are particularly suitable for sealing and obturating dental root canals and root apices. The composition provides a stable barrier to bacterial and fluid leakage in the root canal system of a tooth. In addition, the compositions help promote the growth of new bone and tissue surrounding the root-tip area or dentin tissue that covers an injured or amputated pulp.

Abstract: A method of polishing a tooth surface without mechanical abrasion is provided. Kits and compositions are also provided.

Abstract: The invention provides a dental method including forming a polishing member sufficient, when rotated, to polish a cut unpolished dental tooth surface to a surface roughness of less than 0.07 sRa ?m and, to polish an unpolished dental restorative material supported by a tooth in a patient's mouth to a surface roughness of less than 0.03 sRa ?m. The dental polishing material preferably includes elastomeric polymer impregnated with blocky synthetic diamonds. The synthetic diamonds effectively have particle sizes less than 50 microns. The synthetic diamonds are more than 50 percent by weight of the dental polishing material.

Abstract: The application of a dental material to a site in the oral cavity includes the application of vibrational energy and heat to the dental material in order to substantially impart a preselected or desired viscosity to the dental material.

Abstract: The specification describes an applicator for the treatment of teeth with small amounts of dental materials, such as polymerizable sealants and adhesives, prophylactic treatment materials and the like. The applicator is in the form of a disposable tube having an applicator brush at one end. The tube is fitted to an applicator head that facilitates drawing an amount of the material into the tube and the selected filling of the brush. The applicator may include an elongated member having an applicator head that contains a chamber enclosing a similarly-shaped resilient member. A closure fits over the end of the applicator head and serves to close off the base of the chamber and seal the peripheral edge of the resilient member to prevent leakage. The closure is provided with a smaller chamber which communicates with a channel extending out through the closure and adapted to receive the disposable tube. The channel is positioned at an angle to the main body of the applicator.

Abstract: There are several techniques that are recommended for removal of cement after cementation of castings, veneers, and all ceramic units. With the introduction of resin and resin ionomer cements and their inherent hardness after setting, removal of excess cement has become more difficult. To determine by means of an in vitro study whether the marginal integrity and seal of indirectly fabricated restorations cemented with a resin-based cement are affected by the technique of cement removal. Materials & Methods. Chamfer preparations were made on extracted human teeth. Impressions of the preparations were pour in die stone and wax patterns were fabricated and cast in gold using conventional laboratory techniques. A resin cement was used for cementation and 5 techniques (three castings per technique) were employed for removal of excess cement. After cementation the samples were immersed in methylene blue dye solution for 24 hours and sectioned.

Abstract: A tooth surface treatment composition includes an acidic component which is at least one water-soluble acid in an aqueous solution, such that when the composition is applied to the tooth surface and not subsequently washed, it will increase the adhesiveness of the tooth structure. A method of treating a tooth structure includes contacting the tooth structure with such a composition.

Abstract: A method of restoring a tooth using a dental construct of the type wherein the construct is placed onto the tooth using a dental cement to bond the construct to the tooth. After placement of the construct onto the tooth, excess cement is removed with a soft, pointed brush. The dental margins are then brushed with a photocurable dental resin cement which is the same as or different from the dental cement used to bond the construct to the tooth. The resin cement is then light cured.
