Abstract: The present invention provides an improved rotary handpiece for cleaning and enlarging the root canal of a tooth with a rotary endodontic file. The handpiece includes a retractable support rod attached to and extending from the handpiece positioned adjacent and substantially parallel to the endodontic file. The support rod is adapted to rest on a tooth whereby the retraction of the support rod controls the advance of the endodontic file into the root canal. The control of the advance of the endodontic file insures that the file does not self thread into the canal or become excessively loaded whereby it sticks or breaks off while the root canal is being cleaned and enlarged.

Abstract: A hydraulic endodontia device and method comprised of a primary obturator rod having an objective tip end with at least one spill gate integrally formed therewithin and a handle end, the primary rod being generally cylindrical in shape and gradually diminishing in circumference from the handle end to said tip end. The invention is further defined by a plurality of secondary obturator rods each having an exterior convex side and an interior concave side. The interior concave side of each secondary rod glides upon the primary rod or the exterior convex side of an underlying secondary rod in cooperative association therewith when the open spill gate, the primary rod is inserted into the extirpated root canal until it reaches the distal end at the tip end, whereby narrowing of the distal root canal end constricts the spill gate to effuse cement to the apical area. Additional cement is applied to a plurality of secondary rod interior concave sides which are then inserted within the canal one rod at a time in cooperative association with the primary rod until complete obturation is achieved.

Abstract: An endodontic apparatus and related method for the instant detection of the anatomical structure of a tooth and for the restoration of a dead or severely decayed tooth using induced fluorescence spectroscopy. A root canal probe having an optical fiber through its center transmits excitation light into the tooth's root canal. The excitation light induces the tissue within the root canal to fluoresce. The fluorescent light is collected by the optical fiber and transmitted back to a sensor that generates electrical signals indicative of the intensity of light within predetermined wavelength bands. The electrical signals are processed to identify the tissues within the root canal. The probe may include a slightly conical metal surface having flutes for shaving and removing dentin from within the root canal. Using the fluorescent emission properties of the tissues of components of a tooth, the entrance of the root canal is located. The root canal is cleaned and shaped and the apex of the root canal located using the difference between the fluorescence spectrum of the apex and the root canal. The root canal is sealed and filled by a light cure restorative delivered into the root canal through a tube. The light cure restorative is activated by light transmitted into the root canal by an optical fiber. The light activation and polymerization of the light cure restorative can be controlled by monitoring the intensity of the restorative's fluorescence spectrum.

Abstract: Novel tool operating apparatus is exemplified in a dental treatment device capable of driving alternatively at least a first tool and a second tool, each tool being intended to execute a different form of motion, with a single tool driving means to which each of several different tools can be removably coupled. The driving means includes a rotatable drive shaft fitted with tool engagement means in the form of a disc affixed to the shaft and lying in a plane that makes an acute angle with the rotational axis of the shaft. One tool can be fitted over the shaft to engage the disc so as to rotate the tool with the shaft. A second tool can be fitted over the shaft so that the shaft can rotate within the tool, but the tool will not rotate with the shaft. The second tool has means for cooperating with the shaft so as to execute an oscillatory motion relative to the shaft axis. Tools capable of two optional forms of oscillatory motion are disclosed--in one the motion is parallel to the axis of the shaft; in another the motion is nutational. The drive shaft can be provided with a fluid passage on its rotational axis through which to provide fluid such as a dental treatment agent to the tools, and each form of tool can be fitted with ducts for dispensing such an agent. Further tools suitable for endodontal use are disclosed.
