Abstract: Disclosed herein is an instrument for measuring an endodontic length, which measures and indicates the distance from a pointed tip of a cutting tool to a root apex in order to prevent the pointed tip of the cutting tool from going over the root apex when a root canal is perforated by the cutting tool for an endodontic treatment of a root canal of a tooth. The endodontic length measuring instrument is equipped inside a unit chair system installed in a consultation room of a dental clinic and allows a monitor mounted on the unit chair system to display a measurement result of the endodontic length, thereby making a medical treatment of a root canal easy, easily providing a measurement result of the endodontic length to a doctor, and displaying treatment and measurement results of the root canal in various and precise ways. The measuring instrument provides a scaled-up image of the remaining distance from the pointed tip of the cutting tool to the root apex when the pointed tip of the cutting tool reaches an area which demands a more precise measurement result, thereby increasing safety and accuracy in perforation of the root canal.

Abstract: An inspection equipment is provided by which the endodontic file is examined and judged as to if it reaches to its critical strength. When an appropriately selected endodontic file out of the endodontic files 11, 12, 13 in the kit case 1 is set at the file sample holding portion 5 in the kit case 1 and data corresponding to the endodontic file is input from the data input portion 22, the electric resistance value on the file portion of the endodontic file measured by the resistance measuring portion 20 and the resistance value on the critical strength with correspondence to the data on the file read-out from the RAM 23 are brought together and compared by the inspection unit 30. If the calculating judgement portion 25 makes a judgement to the file to reach its critical level of strength in the cumulative damage, the alarm 19 issues an alarm sound, so that an endodontist or dental assistant knows that the file is not usable any more and should be discarded. As a result, the partially damaged file has no risk to be broken inside the occluded root canal and nickel-associated risk can be eliminated because the partially damaged file can be removed from the continuous service condition according to the present invention. Hence, a safe and reliable endodontic therapy can be practiced.

Abstract: An endodontic device for measuring and indicating the depth of penetration of a probe in a root canal of a tooth during a root canal operation includes a meter having a pair of juxtaposed, graduated scales for respectively indicating probe penetration depth in a first broad range of penetration within the root canal, and a second, relatively narrow range of penetration therein, adjacent the apex of the canal, and further includes a bidirectional indicator pointer to provide a precise, accurate visual indication of the probe penetration depth, particularly when such probe is immediately adjacent the apex of the canal. An a.c. measurement signal derived from a d.c. powered oscillator circuit is passed through the probe to a bridge circuit which measures the probe resistance, and thus the position of the probe relative to the canal apex, and also inverts the phase of the measurement signal when the probe reaches a prescribed penetration depth close to the canal apex. A pair of parallel coupled discriminator circuits sense the phase of the measurement signal and are respectively operative to selectively swing the indicator pointer in one direction when the probe is in the first broad penetration range thereof to produce a reading on one of the scales, and reverse the swing direction of the indicator pointer upon sensing a phase change in the measurement signal to produce a reading on the second, expanded scale associated with the second narrow probe penetration range immediately adjacent the canal apex.
