INTRODUCTION The aim of this study was to evaluate the accuracy of two electronic apex locators (Smarpex and NovApex) in detecting apical perforation. MATERIALS AND METHODS After access cavity preparations, the working length was determined by the first examiner before and after perforation with a stereomicroscope by introducing a K-file size 10 into the canal and size 25 K-file up to the per...

background: the aim of this study was to compare the accuracy of the apex-locating functions of dentaport zx, raypex 5 and endo master electronic apex locators (eals) in vitro. materials and methods: thirty extracted human single-rooted teeth with mature apices were used for the study. the real working length (rwl) was established by subtracting 0.5 mm from the actual root canal length. all tee...

The success of an endodontic treatment relies on a correct working length determination. The canal terminus must be detected accurately and a precise control of the working length during the endodontic treatment must be maintained. The aim of this study was to investigate the working length determination in vivo with the Quill Apex Locator® for apical limit established at 1 mm short from the ap...

Background/Aim: This study aimed to evaluate the precision of Raypex 6 apex locator in locating apical constriction (AC) and major foramen (MF) during a root canal treatment compared with microscopic evaluation. Another aim present was accuracy presence different irrigating solutions (NaOCl, saline, EDTA, etidronic acid-HEBP). Material Methods: One hundred nine patients were included this rando...
