The root canal length measuring apparatus includes a measurement electrode which is inserted into a root canal, an oral electrode which is held in an oral cavity, a measuring section which applies an electric measuring signal between the measurement electrode and the oral electrode and specifies an apex position so as to measure a root canal length, a memory means which stores position data corresponding to a position of the measurement electrode in a root canal acquired by the measuring section, and an operating means which instructs the memory means to store the position data.

Abstract: The invention intends to provide a dental diagnostic device capable of detecting whether or not an electric leakage path which departs from a root canal, bypassing an apex is contained in a conductive path. The dental diagnostic device includes a measuring electrode, an oral electrode, a measurement signal applying means, a measuring means and a detecting means. The measuring electrode is inserted into a root canal of a tooth which is a diagnosing object. The oral electrode is brought into electric contact with oral mucosa. The measurement signal applying means applies a measurement signal in between the measuring electrode and the oral electrode. The measuring means obtains data corresponding to the electric characteristic of at least part of a conductive path between the measuring electrode and the oral electrode based on measurement of electric response to the measurement signal.
