The working length is considered the distance between a coronal reference point and an apical level, in order to obtain the instrumentation and obturation limit [1]. This mensuration is one of the main factors in endodontic treatment success [2]. Previous determination of working length is critical to cleaning, shaping and obturation of radicular canals and has to be carefully measured [3]. The objective of this study is to evaluate the accuracy of three apex locators using four irrigant solutions to determine the working length of root canals. Material and methods: thirty unirradicular teeth were used. Teeth were randomly divided into three groups, in order to establish the working length, using different apex locators: Raypex 6, Endo EZE and RootOR. Four different irrigant solutions were used combined with the apex locators: saline solution (0.9% sodium chloride), 2% chlorhexidine digluconate, 18% EDTA and 5.25% NaCLO. Real working length (RWL) was determined using a #15 K-file in each specimen until the end of the file was visualized in stereoscopic microscopy. Scores (%) were attributed to each difference found between the working length gave by the apex locators and the RWL. Influence of Irrigant Solutions and Apex Locators in Working Length DeterminationResults: there was a significant difference between the RWL and that one found with the apex locators Raypex 6 and RootOR; however, Endo EZE did not show statistical differences. The four different irrigant solutions did not show statistically differences between then. Conclusions: the precision to estimate the working length with Raypex 6 and RootOR was affected by the different irrigant solutions in the root canal; Endo EZE was the most accurate apex locator to estimate the RWL.Abstract

“…Similar result has been reported in a recent study by Altunbaş et al ., where least accurate results were found in the presence of NaOCl in teeth with perforation when using Dentaport ZX. [ 13 ] The least accuracy in the presence of heated NaOCl could be due to an increase in chlorine content with increase in temperature. Furthermore, the decomposition rate of unstable hypochlorite anions into chlorate and chlorine ions is increased with increase in temperature, which in turn may affect the accuracy.…”

Aim:The present study was aimed to compare the accuracy of Root ZX Mini and Propex II in the presence of 0.1% octinidine dohydrochloride (OCT), 2% chlorhexidine gluconate (CHX), and 5% sodium hypochlorite (NaOCl) heated and nonheated before and after preparation.Materials and Methods:Eighty extracted single-rooted teeth were selected for the study and decoronated. Teeth were mounted in an alginate model. Actual working length (AL) was measured using a stereomicroscope under ×4 magnification. Electronic working length measurements were recorded using Root ZX Mini and Propex II apex locators in the presence of 0.1% OCT, 2% CHX, and 5% NaOCl (nonheated and heated to 60°C) before and after preparation. Mean and standard deviation differences before and after preparation were calculated and statistically analyzed using analysis of variance and paired t-test.Results:The accuracy of Root ZX Mini before and after preparation within ±0.5 mm of AL was consistently high in the presence of irrigants than Propex II. 5% NaOCl (heated and nonheated) showed more variation than the other irrigants, in the working length determination in both the apex locators.Conclusion:Electronic length measurements were shorter with heated and nonheated 5% NaOCl and longer with 0.1% OCT and 2% CHX for both the electronic apex locators.

“…It was not possible to compare the Rootor with other existent studies because of the lack of research on this device's location of horizontal fractures. Altunbaş et al 14 reported that the Dentaport ZX and Rootor detected the root canal perforations within a clinically acceptable range. These results are in agreement with the above-mentioned studies.…”

“…12,13 The Rootor (Meta Biomed Cheongwon-gun, Korea) is a multiple-frequency EAL that uses two frequencies (0.5 and 5 kHz). 14,15 No comparative analysis has been performed regarding the use of these EALs for locating horizontal fractures. Thus, the aim of this investigation was to evaluate the ability of the Dentaport ZX and the Rootor EALs to determine simulated horizontal root fractures in vitro using an alginate model.…”

The aim of this study was to evaluate in vitro the effectiveness of the two different electronic apex locators (Dentaport ZX and Rootor-EALs) in locating simulated horizontal root fractures. Materials and Methods: Forty extracted human single-rooted teeth with mature apices were randomly divided into two groups of 20 teeth each. An incomplete horizontal fracture was simulated by preparing a with a 0.25 mm thick disk in the middle and apical portion of the root and the teeth were mounted in an alginate mold. The electronic measurements (ELs) of the simulated root fractures were established with a size 10 K-file by each EAL in both fracture levels. The actual canal lenghts (ALs) were measured under a stereomicroscope. The ALs were subtracted from the ELs of the fractures. The data were analyzed using the Mann-Whitney U and the Wilcoxon signed-rank tests at a significance level of P < .05. Results: The mean differences between the ELs and ALs were-0.12 ± 0.27; 0.09 ± 0.38;-0.10 ± 0.25; 0.18 ± 0.53 mm in the Dentaport ZX and Rootor groups and middle and apical horizontal fracture levels, respectively. The Dentaport ZX performed measurements within ±0.5 mm in 18 and in 19 samples while the Rootor performed in 12 and in 11 samples, middle and apical horizontal fracture levels respectively. Statistically, significant differences were found among the EALs at both horizontal fracture levels (P < .05). However; no statistically significant differences were found between the fracture levels in each of the EALs (P > .05). Conclusions: The Dentaport ZX measurements were shorter than ALs whereas the Rootor measurements were longer than Als. Furthermore, the number of measurements obtained within ± 0.5 mm in Dentaport ZX is more than that of Rootor. Under the conditions of this study, the Dentaport ZX group showed an acceptable determination of the horizontal root fracture.
