Abstract
Recently electronic apex locators have been used widely in root canal treatment. but, accuracy of electronic . apex locators is contEoversial. -The purpose of this study was to gvaluate the accuracy of Apex Finder A.F.A.(EIE Analytic Technology, U.S.A.) in vivo compared with Root-Zx and radiograph.
The root canal lenghs were determined with Root-Zx(32 tooth) in before pulp extirpation and after pulp extirpation. Then the radiographs were taken with a file in the canal. The root canal lenghs were determined with Apex Finder A.F.A.(21 tooth) in before pulp extirpation and after pulp extirpation and under NaOCI. Then the radiographs were taken with a file in the canal.
The results were as follows :
1. There was no significant statistical difference in Root-Zx between before pulp extirpation and after pulp extirpation (p > 0.05).
2. There was no significant statistical difference in Apex Finder A.F.A. between before pulp extirpation and after pulp extirpation(p > 0.05). But, there was significant statistical difference under NaOCI(p ( 0.05).
3. There was no significant statistical difference in accuracy between Root-Zx and Apex Finder A.F.A.
