An endodontic tool for activating a disinfectant liquid sprayed in a cavity of a tooth, includes: a body, elongated along an axis and including a handgrip, for allowing an operator to hold the tool; a tip, connected to the body, configured to be immersed in the liquid; an actuator associated with the body and configured to transmit a vibration to the tip; a heater, associated with the body and configured to heat the disinfectant liquid in the tooth. The heater is designed to heat the tip and the tip is designed to heat the disinfectant liquid.

There is provided an endodontic apical plug including a wall, an open base and a closed tip, wherein the wall defines a longitudinal cavity extending from the open base of the plug to the closed tip of the plug. A width of the longitudinal cavity is greater at the open base of the plug and narrower towards the closed tip of the plug, the longitudinal cavity being configured to accept an injection tube connected to the injection device for filling the plug towards a root of a tooth. The longitudinal cavity comprises at least one lateral longitudinal opening in the wall of the plug, the at least one lateral opening being configured to, in use, enable a tooth filling material to pass through the at least one longitudinal opening and into a tooth.

A carrier based root canal obturator, with the carrier core provided with predefined surface features including axially and/or circumferentially distributed protrusions along the surface of the carrier core. The protrusions provide a stop, and also a support for the layer of surface coating dental filling/sealing material to guide insertion and seating of the carrier based obturator in the root canal. The carrier core includes a conical body having a flat surface in the axial direction, with a conical taper. The surface features defined at the surface of the conical body include discrete protrusions at two or more axial locations. In one embodiment, the heights of the protrusions are substantially flush with the external surface of the coating material. In manufacturing, the protrusions of the carrier core provide a mechanism to set the thickness for over-molding the surface coating layer onto the carrier core.

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.

A combination heater assembly made of positive temperature coefficient (PTC) material such as barium titanate ceramic that may be self-regulating. A dental compule 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, an orifice or opening positioned at one end of the compule, an inner chamber; and extrudable dental material held within the inner chamber.

Devices and methods for dispensing material from a dental handpiece. In one example, the method includes receiving an input that indicates that an amount of the material is to be dispensed from the container of the dental handpiece. The method also includes rotating an electric motor to rotate an imbalanced mass to vibrate a vibration transmission element that vibrates the material in the container. The method also includes dispensing the amount of the material from the container with a piston based on the input.
