摘要： A dental bleaching gel composition having a long shelf life for use with an activator system to cause accelerated bleaching action of a peroxide bleaching agent in the bleaching gel composition when applied upon a tooth surface and to a method for applying and activating a dental bleaching gel upon a tooth surface for cosmetically whitening the tooth and/or for the treatment of stains or discolorations over a shortened time period. The dental bleaching gel has a pH independent thickening agent, a stabilizing agent for the peroxide bleaching agent and a FD & C approved dye. The activator system comprises an activator for accelerating the bleaching action of the peroxide bleaching agent and an applicator for storing the activator in a dry form separated from the bleaching gel composition such that upon contacting the applicator to the bleaching gel composition the peroxide bleaching agent contained in the gel is activated with the applicator being used to substantially simultaneously apply the bleaching gel to the tooth or teeth to be bleached.

摘要： A system for heating and extruding dental material from a compule, the system comprising a combination heater assembly (405) made of positive temperature coefficient (PTC) material such as barium titanate ceramic that may be self-regulating. A dental compule (403) may be generally cylindrical, or another shape, and may hold a dental (e.g. composite) material. The compule may be made from conventional plastic or thermally conductive plastic. A compule may also be made from electrically conductive plastic that is self-heating when an electric current is passed through the compule. A compule may be generally cylindrical and include an electrically conductive polymer that may exhibit PTC characteristics while generating heat when electric current is applied to the polymer through two flat contact areas each disposed along one portion of the generally cylindrical compule (403), an orifice or opening (412) positioned at one end of the compule, an inner chamber; and extrudable dental material held within the inner chamber.

摘要： A dental bleaching system and method having two separated components adapted to be dispensed from a single dispenser as a mixed viscous dental bleach composition. The first component comprises aqueous hydrogen peroxide and the second component includes a gelling agent, catalyst, a ph alkaline buffer, a redox color indicator adapted to oxidize in the presence of a peroxide from a visible color into a neutralized color and a second dye stable in the presence of a peroxide with the concentration of the redox color indicator selected relative to the second dye such that the redox color will predominant during the bleaching operation and the second dye will predominant at the end of a controlled time period corresponding to when the bleaching treatment may be discontinued.

摘要： A dental device for assisting in the filling and curing of a dental restoration when used with a light guide. The dental device includes an insert member and either a conical adapter or handling means adapted to accommodate a light guide. The insert member is tapered at one end thereof has an indicator means to monitor the depth of the restoration to the pulpal floor and to provide alignment of the preparation relative to the marginal ridge of the adjacent tooth. The conical adapter has an opening at the base to accommodate the light guide and an opening at the apex to accommodate the insert member. The handling means funtions in combination with the insert member to form an instrument into which a dental light guide can be mounted and has an elongated body of triangular shape with a first and second opening at the opposite ends of the elongated body adapted to receive insert member(s) which are interchangeable for facilitating mesial and distal contact with an adjacent tooth.

摘要： A dispenser for controllably heating a compule of dental material removably inserted in the dispenser and for extruding dental material from the compule. The dispenser includes an elongated tubular barrel having a substantially semi-cylindrical front end to accommodate the body of the compule, a cavity at the front end of the dispenser open to the atmosphere and a slot disposed transverse to the longitudinal axis of the cavity for accommodating an end flange of the compule when the compule is inserted into the dispenser. The dispenser further includes a plunger reciprocally mounted in the tubular barrel in alignment with the longitudinal axis of the cavity for engaging the compule to express dental material from said compule by means of a motorized assembly or manual control under the control of the operator and a heating unit disposed in the cavity at the front end of the dispenser for heating the compule.
