摘要： Activating endodontic points (28a, 28b) and/or other dental tools are sized and configured to be placed in the root canal (12) of a tooth (10). The activating endodontic points (28a, 28b) or dental tools are coated or impregnated with a curing agent that initiates or accelerates polymerization of a sealer or filler composition (32) when placed in contact with the sealer or filler material (32). Curing agents can include amines that can destabilize a peroxide in the sealer or filler material (32) to initiate or accelerate polymerization, or they may comprise peroxide. An implement can be dipped in a concentrated curing composition just prior to inserting the implement into a root canal to contact the filler or sealer composition. Kits may include a plurality of curing agent compositions having different concentrations and/or amounts of curing agent. Kits may also include a curable resin material that includes a first part of a multi-part curing system and a curing composition that includes, as curing agent, a complementary part of the curing system.

摘要： A temporary dental cement composition temporarily affixes a dental prosthesis or appliance to a tooth or other dental substrate. The dental cement includes a mixture of: (i) an ion leaching agent; (ii) polycarboxylic acid; (iii) sugar; and (iv) water. The sugar is added in a sufficient amount that the ion leaching agent and polycarboxylic acid form a hardenable adhesive having an adhesive matrix which forms a relatively weak, temporary bond, as opposed to a permanent bond. The temporary cement composition is compatible with subsequent deposition of typical bonding materials, such as resin luting agents as well as non-resin permanent cements.

摘要： An exoskeleton support (114) and associated placement system (100) for use in placing a thin, flexible dental treatment strip (104) over a person's tooth surfaces. The exoskeleton support (114) includes an exoskeleton body (102) that is curved so as to approximate the curvature of a person's dental arch. The exoskeleton support (114) includes an inner surface (108) that is oriented toward a person's tooth surfaces during use, an outer surface (110) oriented away from the person's tooth surfaces during use, and adhesive material (112) for temporarily holding or attaching a flexible dental treatment strip (104) to the inner surface (108) of the exoskeleton support (114). The exoskeleton support (114) allows a user to more easily and accurately place a dental treatment strip (104) on tooth surfaces to be treated.

摘要： Valve syringes of the invention include a syringe barrel (12) and an applicator valve (30) adapted to rotate relative to the barrel (12) between closed and open positions. In the open position, one or more slots in the applicator valve (30) align with one or more holes in a discharge end of the syringe barrel (12) in order to allow fluid material to flow therethrough. In a closed position, the contact surface of the applicator valve (30) occludes the holes in the barrel (12) in order to seal them and prevent flow of fluid material therethrough. The valve syringe (10) may include structure that increases the sealing engagement between the syringe barrel (12) and applicator valve (30) when rotated toward at least one of the open or closed positions. The applicator valve (30) may include an applicator tip that is either integrally of detachably connected to the applicator valve (30). The valve syringe (10) may also include a plunger (20) adapted to expel fluid material contained in the syringe barrel (12) through the discharge end and into the applicator valve (30). An end of the plunger (20) may be tapered or otherwise configured so as to conform to the shape of the discharge end of the syringe barrel (12).

摘要： Dental bleaching devices (10) in the shape of a dental tray, strip or patch include a barrier layer (18), a dental bleaching composition (28), and a protective adhesive composition (24, 26) that protects a person's gums from the dental bleaching composition during use. The barrier layer (18) protects the bleaching and protective adhesive compositions (24, 26, 28) ftom saliva or moisture during use. The dental bleaching composition is positioned (28) so as to contact a person's tooth surfaces when the bleaching device (10) is in use. The protective adhesive composition (24, 26) is positioned so as to shield a person's gums from the bleaching composition when the bleaching device is in use. The dental bleaching composition (28) and protective adhesive composition (24, 26) can be in the form of a gel or they may be substantially solid. They preferably include a tissue adhesion agent comprising a hydrophilic polymer.

摘要： A dental bracket (104) is designed and used to attach a medicament-releasing pellet (102) to a tooth. The dental bracket comprises a base (1060) for attachment to a tooth and a socket (108) for receiving and retaining a correspondingly sized and shaped medicament-releasing pellet (102). The pellet (102) medicament-releasing is designed to provide slow release of fluoride or another medicament over a desired period of time. The dental bracket (104) may be included within a kit that also includes one or more of a bracket placement device, a medicament-releasing pellet (102), an etch, or an adhesive resin. The placement device aids the dental practitioner in placing the bracket (104) on a patient’s tooth. The bracket (104) may be installed by a dental practitioner and may remain attached to the patient’s tooth for up to 20 years.

摘要： Treatment compositions in the shape of a dental tray (10), strip or patch include an adhesive composition (20) and a treatment gel (28). A barrier layer (18) may be included to form a treatment device (10) that protects the treatment gel (28) from saliva or moisture during use. The adhesive composition (20) is substantially solid and has increased adhesiveness to oral tissue when moistened with saliva or water. The adhesive composition (20) is formed from an intermediate composition that is heated to drive off the solvent. Using a treatment gel (28) separate from the adhesive composition (20) improves the potency and stability of the active agent prior to use.

摘要： An endodontic irrigator tip (20) having a cannula (60) with an annealed distal portion (65) and a proximal portion (63) enables the cannula (60) to easily move within a root canal. The cannula (60) extends from a hub (22) that is adapted for coupling with a syringe or other delivery device. The cannula (60) has an outlet orifice for delivering an irrigant out of the endodontic irrigator tip and into the root canal. The outlet orifice may be defined by a rounded rim that optimally enables the distal insertion end of the cannula to be advanced within the root canal.

摘要： A delivery tip (14) for use on a delivery device for applying a dental composition to tooth surfaces includes a tubular member (30) having a proximal end (32) and a distal end (34). The proximal end (32) of the tubular member (30) is coupled to the delivery device, while a plurality of fibrous bristles (50) are disposed at the distal end (34) of the tubular member (30). The fibrous bristles (50) are attached to the distal end (34) of the delivery tip (14) in such a manner that the composition can be delivered through a passageway in the tubular member (30) without interference from the bristles (50). The fibrous bristles (50) can be used in an agitating action to remove entrapped air bubbles from the applied composition, and can also be used to coat the composition on tooth surfaces.

摘要： The invention generally provides for a dental wedge (10) with flexible members (20). The dental wedge (10) comprises a wedge shaped body (12) with sides that are serrated with multiple flexible members (20) extending away from the sides. When the dental wedge (10) is inserted between adjacent teeth (50, 52), the flexible members (20) bend and conform to the surfaces of the teeth (50, 52). This generally increases the frictional surface area between the dental wedge (10) and the teeth (50,52), thereby providing the dental wedge (10) with increased retention capabilities for remaining in place between the teeth (50, 52). In some embodiments, the flexible members (20) also comprise edges and/or gritty surfaces for further increasing the retention capabilities of the dental wedge (10).
