Abstract
The present invention provides a root canal length measuring apparatus and a root canal treatment apparatus which can acquire a position of a measurement electrode with high reproducibility in the same root canal. 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.
