Abstract

Objective To evaluate the accuracy of the fully automatic root canal measuring device (ROOT ZX). Methods 494 canals of 178 patients with 217 teeth were divided into two groups. The experimental group was measured by ROOT ZX. The control group was estimated manually. The accuracy was evaluated by radiological observation. Results The successful ratio of root canal therapy of experimental group was obviously higher than other group( p 0.05 ). Conclusion The ROOT ZX is more accurate in root canam length measuring.
