OBJECTIVES The purpose of this in vitro study was to evaluate the accuracy of working length (WL) determination of four electronic apex locators (EALs), namely, Root ZX (RZX), Elements diagnostic unit and apex locator (ELE), SybronEndo Mini Apex locator (MINI) and Propex pixi (PIXI) using Stainless steel (SS) and nickel-titanium (NiTi) hand files. The null hypothesis was that there was no diffe...

AIM The purpose of this study was to compare the working length determination done using three methods, namely, apex locator (Foramatron D-10, Parkell), radiovisiography (Planmeca) and conventional radiography (Prostyle intra, Planmeca). MATERIALS AND METHODS In this experiment, to determine the working length, 35 single-rooted teeth were selected and each tooth was subjected to all the three...

INTRODUCTION The aim of this in vitro study was to evaluate the correlation between accuracy of Root ZX electronic foramen locator and root canal curvature. METHODS AND MATERIALS One hundred and ten extracted mandibular molars were selected. Access cavity was prepared and coronal enlargement of mesiobuccal canal was performed. A #10 Flexofile was inserted into the mesiobuccal canal, and a rad...

o bjectives: correct determination of working length is an important step for suc- cess of endodontic therapy. conventional radiography has limitations in providing the accurate location of apical foramen. for this reason, electronic apex locators (eals) were developed to shorten the treatment time and decrease the radiation dose. the aim of this study was to evaluate the accuracy of root zx ea...
