Claims

[Claims for Utility Model Registration] 1. An electrode member 1 to which a non-ground lead wire a led out from a root canal length measuring device A is connected to the rear end, and an electrode member 1 attached to the electrode member 1 and inserted into the root canal of a tooth. In a dental root canal length measurement probe including a reamer 2, a guide groove 11 into which the shank 21 of the reamer 2 can be inserted is provided in the front end of the electrode member 1, and the guide groove 11 A reamer holding hole 12 perpendicular to the guide groove 11 is formed by arranging reamer turning fans 4121.121 diagonally opposite to each other at the bottom of the reamer 2. A root canal length measuring probe characterized in that a compression spring 3 is fitted around the electrode member 1 so that the shank 21 of the holding hole 12 can be pressed against the inner circumferential wall of the holding hole 12 to elastically hold it. 2 A receiving blade terminal 13 is fitted to the rear end portion of the electrode member 1, while a plug terminal a1 that can be fitted into and detached from the receiving blade terminal 13 is fixed to the tip of the lead wire a.
The probe according to claim 1, wherein the probe is detachably connectable to the lead wire a.
