摘要： A color-changeable cement composition for dental use is disclosed, which comprises a first component comprising a metal oxide as a major ingredient, and a second component which can react with the first component to form a set body, wherein the composition contains a substance which changes its color tone with the change in pH so that the color tone of the cement composition can change upon intital setting of the cement composition. The composition enables one to visually observe the degree of setting of the cement composition.

摘要： Dental restorations are prepared by preparing a cavity within a carious tooth for receiving a dental amalgam filling;Coating the surfaces of the cavity with a layer of an adhesive-metal lining composition, the metal of the composition being characterized by the capability of being amalgamated by diffusion of the mercury from a subsequently applied dental amalgam filling, and which is further characterized by a corrosion resistance which is higher than the corrosion resistance of the subsequently applied dental amalgam filling; and packing the remaining adhesive-metal coated cavity with Ag-Hg-Sn dental amalgam, whereby free mercury present in the amalgam is diffused into, and amalgamates with the metal of the adhesive-metal lining coating, so as to form an integral restoration of the dental amalgam and the coating, and the adhesive effectively promotes bonding between the integral restoration and the cavity surfaces.

摘要： This invention provides an adhesion promoter composition, comprising: a primer composition comprising an oxidant having an oxidation potential greater than the absolute value of the E.sup.O reductant of the adherend and optionally a solvent; and an adhesive composition. This invention also provides a method of adhering a restorative material to an amalgam substrate, comprising the steps of: applying a primer composition and an adhesive to an amalgam substrate; hardening the adhesive; and optionally overcoating the adhesive with a restorative material. These methods and materials have utility for applications that require adhesion to existing dental amalgams including, for example, the esthetic veneering of an amalgam restorative with a composite restorative material, and the repair or modification of old amalgam restorations with a fresh amalgam or with a composite restorative material.

摘要： A dental anchor magazine housing a dental anchor therein is disclosed, where the dental anchor is for anchoring a superstructure to a tooth. The dental anchor includes threaded sections and an L-shaped manipulating end section joined together by frangible reduced thickness portions. The dental anchor magazine includes a body member having a conical front end, and a square shaped rear end for rotating the magazine about its longitudinal axis. A centrally located passageway extends longitudinally through the body member to receive the dental anchor therein. A slot extends transversely through the body member into communication with the passageway for longitudinal movement of the manipulating section of the dental anchor therein. A pair of notches are provided in the wall of the slot for receiving the manipulating section of the dental anchor to prevent movement of the dental anchor towards the rear end when the forward end of the dental anchor is being initially threaded into a channel of a tooth, where the forward end of the dental anchor extends outwardly from the front end of the body member when being threaded into the channel. The square shaped rear end of the body member is engageably received in either a manual holder for manual rotation thereof or a handpiece holder for power rotation thereof by a dental handpiece. Both the manual holder and the handpiece holder include a pin member for advancing the manipulating section to a first one of the notches.
