Prior to root canal treatment at least one undistorted radiograph is required to assess canal
morphology. The apical extent of instrumentation and the final root filling have a role in …

Locating the appropriate apical position always has been a challenge in clinical
endodontics. The cemento-dentinal junction (CDJ), where the pulp tissue changes into the …

Aim To compare the accuracy of two electronic apex locators (EALs) in the same teeth in
vivo. Methodology The working lengths in 20 teeth with a single canal were determined with …

Aim To determine in vivo the accuracy of two impedance quotient apex locators under
clinical conditions. Methodology Electronic working length determination was carried out …

The purpose of this in vitro study was to evaluate the accuracy of Root ZX apex locator to
determine the working length in teeth with simulated apical root resorption. Fifty extracted …

The purpose of this study was to compare the accuracy of a two-frequency (Root ZX) and a
five-frequency (Endo Analyzer Model 8005) electronic apex locator under clinical conditions …

Third-generation electronic apex locators for root canal length determination are very
reliable and are not subject to interference from the contents of the canals. This study …

Objective. The aim of this study was to assess the accuracy of an electronic device (Root ZX;
Morita, Tokyo, Japan) for measuring the root canal length in primary teeth. Study design. The …

Small-diameter hand files are systematically used to determine the initial working length and
to establish patency of the root canal. In wide canals, electronic apex locator accuracy might …
