Effects of simulated lateral canals on the accuracy of measurements by an electronic apex locator.


BACKGROUND Accurate determination of the apical terminus plays a significant role in the success of root canal therapy, but accuracy may be affected by the presence of accessory canals. OBJECTIVE To evaluate the accuracy of a ratio-based electronic apex locator for roots with simulated lateral canals. METHODS Forty-two single-rooted human teeth were… (More)
