 note = {application/pdf, Endocater, the newest electric root canal measuring device, was clinically evaluated on pulpectomy cases. Root Canal Meter was employed as control. The results were as follows: 1. The hand reamer was inserted into the root canal, of which most of the pulp had been previously removed, and the root canal length was measured by Endocater according to the manufacturer's instruction. In 12 (root canals) out of 48 cases, the reamer tips were between 0.2mm and 0.5mm shorter than the root canal length measured by Root Canal Meter at 40μA. In 10 cases, they were between 0.6mm and 2.8mm shorter than the root canal length at 40μA. In the remaining 26 cases, they were more than 3.8mm shorter than the root canal length at 40μA. 2. The cases in which the meter readings of the Endocater -with the working length shortened 1.0mm of the 40μA length- were between -3.0mm and +3.0mm from the central line of the meter, were 38 out of 55 cases (69.0%) at the time of pulp removal, and 47 out of 57 cases (82.5%) at the beginning of the next appointment after the pulpectomy. At this working length, the meter readings of the Root Canal Meter scattered from 28.0μA to 39.0μA, and 78.2% of the pulp removal time or 82.5% of the next appointment were included in this range. 3. Apical seat formation was evaluated by examining the location of master corn tips using X-ray dental photographs taken immediately after the root canal filling. In 39 out of 52 cases (75.0%), apical seats were formed in the range of 0.6mm to 1.2mm short of the root apex. Another 10 cases had apical seats formed between 1.4mm and 2.8mm short of the root apex. 8 cases failed in apical seat formation.},
