The accuracy of root canal measurements using the Mini Apex Locator and Root ZX-II: an evaluation in vitro.

OBJECTIVE The aim of this in vitro study was to compare the capacity of the Root ZX-II and Mini Apex Locator, electronic apex locators (EALS), to prevent overestimated working length. STUDY DESIGN Forty extracted human teeth were used for the study. The cervical portion of each canal was flared using Gates Glidden drills and the teeth were embedded in an alginate model. Canals were irrigated ...
