A Clinical Study on Endodontic Meter in Comparison with Root Canal Meter

A clinical study was done in order to discover the relationship between the readings of the Endodontic Meter and the Root Canal Meter, the latter of which had been used as the standard. These two electric devices were also studied on their usefulness in determining the working length for the preparation of an apical seat. The results were as follows: 1. When a 25 or 30 size reamer was inserted into the root canal to the apical portion on the pulpectomy and at a 40μA reading of the Root Canal Meter, the mean reading of the Endodontic Meter was 41.0μA. 7 out of 17 cases ranged from 40.0μA to 40.5μA. At the beginning of the first treatment after the pulpectomy, the reading of the Endodontic Meter was in the range of 40.0±0.2μA on 10 out of 14 cases. It was recognized that the readings of the Endodontic Meter were more definite on root canal treatment after pulpectomy than during pulpectomy. 2. Using 40, 50 or 60 size reamers according to the kind of teeth, root canals were prepared to 1.0mm short of the root canal length at 40μA by the Root Canal Meter. At this working length, neither the Root Canal Meter nor the Endodontic Meter could give definite readings, and the readings of both were scattered. This method appears to be useful in determining the working length for the preparation of apical seats
