Methods and apparatuses for taking, using and displaying three-dimensional (3D) volumetric models of a patient's dental arch. A 3D volumetric model may include surface (e.g., color) information as well as information on internal structure, such as near-infrared (near-IR) transparency values for internal structures including enamel and dentin.

Disclosed herein is an obturator and methods of manufacturing an obturator for filling an endodontically prepared root canal. The obturator comprises an elongated carrier having a distal end, proximal end, and working portion with a combination of filler materials having multiple viscosities coated on the working portion.

A dental device is improved in its ability to produce hydroxyl apatite by having a layer of mineral trioxide aggregate (MTA) deposited thereon. A tile of MTA is prepared, heat treated and sintered to produce a micronized tile of MTA that can then be deposited by physical vapor depositions, hot isostatic pressing, molding or other conventional technique.

A motor driven syringe dispenser which has a syringe mounting part, a slider, and a connection for an endodontic motor. The syringe dispenser connects to an endodontic motor which is used to drive a plunger of a syringe placed in the syringe mounting part thereby expressing irrigant into a root canal for root canal therapy.

A treatment instrument can include a fluid platform comprising a chamber and an access port to provide fluid communication between a treatment region of the tooth and the chamber, the chamber having a central axis. The treatment instrument can include a first fluid supply port disposed to direct a fluid stream of a first material into the chamber along a stream axis non-parallel to the central axis. The treatment instrument can include a second supply port distal the first fluid supply port, the second supply port disposed to direct a second material to be entrained with the fluid stream into the chamber.

The endodontic point containing ultrasonic deformable material is a filler for root canal therapy that decreases in viscosity when subjected to ultrasonic waves. Once the point is inserted into a prepared tooth space, such as a prepared and cleaned root canal, the point is subjected to ultrasonic waves. The ultrasonic waves cause the viscosity of the point to lower, thus allowing the point to flow into voids in the tooth space and allow air to escape from the voids. The point then hardens and remains in the shape acquired when at low viscosity once application of the ultrasonic waves is stopped.

A dental tool includes: a hand piece; an endodontic hand file; a stopper, wherein the stopper comprises a first hole for receiving a portion of the endodontic hand file; and a mechanical motion module that imparts mechanical motion to the endodontic hand file. A dental system includes: a hand piece; an endodontic file; and a stopper comprising at least two holes, wherein a first hole receives a portion of the endodontic file, and wherein a second hole receives a portion of a first tube for delivering a liquid to the endodontic file. The dental system can further include a second tube partially contained in a third hole of the stopper for suctioning liquids from a patient's mouth. The dental system can also further include a mechanical motion module.
