Abstract

Provided is a lateral branch detection probe whereby the condition of a lateral branch can be detected merely by inserting the lateral branch detection probe to an apex. A lateral branch detection probe detects, after insertion thereof into a root canal of a tooth, the presence/absence of a lateral branch and the position of the lateral branch in the root canal axis direction, the lateral branch detection probe being provided with a plurality of measurement electrodes extending to different positions in the root canal axis direction at predetermined intervals. The measurement electrodes constitute a measurement terminal group in which each measurement electrode is covered with an insulator except for one end portion, and another end portion thereof is connectable to a detection-purpose power supply on a detection device side.
