OBJECTIVE: To see the accuracy of "ROOT ZX" electronic root canal measurement in clinical endodontic practice. METHODS: Root canal length of 176 anterior teeth were measured by "ROOT ZX",after radiographs were taken,the distance between reamer tip and toot apex was measured,and then compared it with the distance between apical foramen and root apex of extracted teeth. RESULTS: Statistical analysis indicated no significant difference between two groups. CONCLUSION: It shows: that the electronic device can measure the root canal length accurately.It is believed that it has a higher value in clinical endodontic practice.
