Electronic apex locator ‘apical constriction’ reading versus micro-computed tomography landmarks in molars: an in vitro study
The 'AC' reading of the three EALs generally indicated a position slightly coronal to the major apical foramen, irrespective of AC presence. While the three EALs provided comparable readings relative to each other, their accuracy in corresponding to the anatomical AC (when present) varied in this in vitro model, with Root ZX II showing closer agreement with µCT findings.
