Abstract: An intraoral optical probe is provided that includes a distal elongate optical waveguide for interrogating dental tissue. In some example embodiments, the elongate optical waveguide has dimensions suitable for the insertion of the waveguide into an exposed root canal. According to various example embodiments, the elongate optical waveguide, when inserted into an internal region of a tooth, can direct incident optical radiation from the intraoral optical probe directly onto an inner surface, such as an internal surface of a root canal, such that status of the root canal can be interrogated directly. The intraoral optical probe may be employed to provide intraoperative feedback regarding internal dental tissue, such as interoperative feedback pertaining to the interior of the root canal during an endodontic procedure, location of secondary or lateral root canals, location of the apex or tip of the root canal system and or detection of the pulp chamber roof or floor.

Abstract: An apex-locating method and device for determining the depth position of the apex in a dental root canal. It uses a device making it possible to form a circuit including a first probe electrode inserted into the root canal of a tooth, a second electrode in conductive contact with an oral mucous membrane, frequency-generating elements able to produce alternating electrical signals at a number of frequencies, and elements for measuring electrical magnitude of alternating signals in the circuit. Provision is made for exciting the circuit and measuring the levels of magnitude of the alternating signals, respectively at low frequency and at high frequency and for detecting a point of intersection where the two levels measured at low and high frequencies meet and become substantially equal, these frequencies being sufficiently far apart for this point of intersection to exist. This point gives the position of the apex.

Abstract: The discovery of a new coefficient named “Radicular Spectral Attenuation Coefficient-RSAC”, applicable in electronic foramen locators is described. The novelty is the use of the spectral attenuation of a multifrequency electrical current signal, applied through the endodontic file into the tooth canal (TC), to determine the root length and the foramen position. FIG. (2): (2.1), (2.4), (2.8) and (2.2), (2.5), (2.9) are the amplitude and frequency axes, respectively; (2.3) is the electrical current frequency spectrum applied into the TC; (2.6) shows the spectrum exponential decay (2.7) of the signal measured over the TC. In (2.10) the axes (2.4) and (2.5) were logaritmized to linearize the exponential decay. The RSAC is the average inclination of the line (2.11), which is proportional to the distance between the tip of the endodontic file and the apical foramen. The RSAC changes as the tip of the file gets near the foramen.

Abstract: An electronic device for locating the apex of a root canal within a tooth of a dental patient has a display screen on a display component to provide an image indicating when the apex of a root canal has been located. A free end of a first electrical lead is provided for placement within the root canal or in contact with an electrically conductive tool within the root canal. A free end of a second electrical lead is used to establishing a ground on a conductive portion of the dental patient such as a tissue surface within the mouth. The opposite ends of each of the leads is connected to the display component. Removeably attached to the display component is a lead carrier. The detachable lead carrier and the leads mounted thereon can be sterilized as a unit and then attached to the display component, which is bagged in a sterile barrier, for performing the apex locating procedure. The apex locator has one or more mounting structures for placing the display in a location adjacent the patients head, attached to adjacent instrumentation, or attached to the dental practitioner's hand or arm such that the display image is readily visible by the dental practitioner during the apex locating procedure.
