title: Clinical evaluation of the accuracy of the Evident RCM Mark II Apex Locator.
abstract: The accuracy of the Evident RCM Mark II in locating the apical foramen was evaluated in 37 human teeth scheduled for extraction. After extraction, the difference between the position of the apical foramen determined electronically and its real anatomical location was measured under a binocular microscope, using a micrometer mobile in x, y, and z coordinates. The results show that in 86% (n = 37) of the cases, an accurate location +/- 0.5 mm of the apical foramen was obtained.
