Accuracy of Working Length Determination using NovApex and Root-ZX Apex Locators: An in vitro Study.INTRODUCTION
 This ex vivo study evaluated the accuracy of the Root-ZX electronic apex locator (EAL) (J. Morita, Tokyo, Japan) and the NovApex (Forum Technologies, Rishon Lezion, Israel) in determining the working length (WL) during endodontic treatment.


 Then, the canal lengths were measured electronically with both Root-ZX and NovApex apex locators within ±0.5 and ±1 mm.  The accuracy of NovApex apex locator was 85% within ±0.5 mm and 92.5% within ±1 mm.  Both the NovApex and Root-ZX EALs are useful for measuring the WL with high accuracy.
