ABSTRACT
Background and Aim: Radiography is the most commonly used technique in root canal length determination, but its application in pedodontics is difficult due to many problems such as radiation hazards, superimposition of permanent teeth buds and uncooperative children. The aim of this study was to investigate the accuracy of an electronic apex locator (Dentaport ZX) in measuring the root canal length of primary teeth in vivo. Materials and Methods: In this test evaluation study, pulp tissues of 52 primary teeth planned to extraction were removed and the canal length were measured by Dentaport ZX. After extraction, real lengths of canals were measured by using# 15 K-Type file with 0. 1 mm accuracy and both measurements were compared. Data were analyzed by Smirnov Kolmogorov, chi-square, ANOVA and intraclass correlation and p
