Root canal length measuring apparatus and root canal therapy apparatus
First Claim
1. A root canal length measuring apparatus comprising:
- 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 said measurement electrode and said 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 said measurement electrode in said root canal acquired by said measuring section; and
an operating means which instructs said memory means to store said position data.

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.
