Apparatus and methods for endodontic treatment of teeth provide effective cleaning of organic material (such as pulp and diseased tissue) from the root canal system. In an embodiment, a compressor system generates high pressure liquid (e.g., water) that flows through an orifice to produce a high-velocity collimated jet of liquid. The high-velocity jet is directed toward a surface of a tooth, for example, an exposed dentinal surface, and impingement of the jet onto the surface generates an acoustic wave that propagates throughout the tooth. The acoustic wave effectively detaches organic material from dentinal surfaces and tubules. The detached organic material is flushed from the root canal system by the liquid jet and/or by additional irrigation.

An endoactivator tool for activating intracanal reagents in a dental root canal system during endodontic procedures, with the tool comprising a flexible activator tip having a proximal end connected to a coupler to a driver and extending distally from the coupler to terminate at a most distal end, wherein the activator tip being shaped such that when the driver is activated, the coupler will induce vibrations in at least an activating portion of the activator tip, wherein the activating portion comprises at least one curved offset section displaced from the vibration axis in a plane including the vibration axis, wherein the activating portion has a length extending through a prepared dental root canal and a diameter sufficiently smaller than the diameter of the prepared root canal such that the activating portion can vibrate in the dental root canal when activated, and wherein the activating portion being made from a flexible, non-cutting material having a hardness less than the hardness of a root canal wall such that the material will not damage the walls of the canal during use of the tool. The proximal end of the activating portion is connected to a location on the coupler displaced off the vibration axis, and/or the most distal end of the activating portion extends off the vibration axis when the activator tip is at a state not being inserted into a dental root canal. The longitudinal axis of the curved section of the activating portion meanders in a sinusoidal profile.

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.

A hard tissue stent, including an access hole formed in one side, may be placed over one or more of the patient's teeth where the access hole is accurately aligned at a location for drilling to, for example, remove infection. A soft tissue stent may be placed over one or more of the patient's teeth, where the stent can include a mark to cut to create an access flap in the soft tissue. By keeping the flap attached, the surgeon can more easily return the flap to the proper position. The attached surgical guide permits access any area of the jaw and tooth and implanted device. With insertion of a sleeve with custom bores into the guide, the dental surgeon can work in a dry field and accurately manipulate the bony crypt and tooth for many different purposes including root-end preparation, filling and repair of local perforations and cracks.
