The invention relates to a method and an arrangement for the cleaning of a circumferentially closed canal by means of a light guide conducting a laser beam. The entry of the laser beam into the light guide is interrupted when the free end of the light guide is outside of the canal and/or the movement of the light guide within the canal is monitored and that if there is no movement or the movement is below a threshold value then a signal is triggered and/or the laser radiation is turned off or its output is reduced.

A heating device for heating a dental material. The heating device has a body and a socket. The socket is removably received within the body and has a socket wall that forms a receptacle for positioning a container for the dental material therein. The body has a light source for emitting light toward the socket wall in a direction toward the receptacle. The socket wall is at least partially transmissive for infrared light. The heating device allows for heating the dental material within the container.

The invention relates to the application of photon energy to energize dental materials to enhance their physical handling characteristics, efficacy, ability to be delivered, reactivity, polymerization, and/or post-cure mechanical properties, among other attributes.

The present invention discloses an induction heating type dental filling device including a body unit grippable by a user, a filling unit containing a refillable filling material and connected to the body unit so that one side thereof is insulated from the body unit, a heating unit disposed in close contact with the filling unit and heating the filling material using induced current to convert the filling material into a liquid state, a pressing unit for pressing the heated filling material to discharge the heated filling material to the outside of the filling unit, and a shielding unit for shielding the heat and magnetic field of the heating unit. According to this configuration, heat loss through the filling unit may be prevented and clamping force for the body unit may be excellent, so that the efficiency of filling a filling material for dental treatment may be improved.

The present invention relates to methods for the restoration of a decayed portion of an anterior tooth or re-restoration of a previously filled anterior tooth, and to dental matrices and composite resin dispensers that may be used in the methods for the restoration of a decayed portion of an anterior tooth.

A cartridge includes a chamber structure configured to contain endodontic material. An electrically conductive heating layer is provided adjacent to the chamber structure. A first electrode is positioned at one side of the cartridge, with the first electrode being in electrical contact with the heating layer, and a second electrode is positioned at a second side of the cartridge, with the second electrode being in electrical contact with the heating layer. An outer sleeve encases the chamber structure, the heating layer, and the electrodes, with an air gap being formed between the outer sleeve and the heating layer.
