“…This finding is consistent with the findings of Abdullah, Carneiro, Reddy and Malik; whereas they were inconsistent with the findings of Mittal, Khawaja and Yilmaz. (17,(22)(23)(24)(25)(26) Identical results between the two methods indicate that in curved first mandibular molars, radiographic and apex locator methods are both accurate and more curvature and less convergence of these channels during root canal therapy does not affect the accuracy of the apex locator. According to these findings, radiographic measurements were either shorter or equal to the actual WL, except in one case.…”

Introduction:The exact measurement of the root canal length is of great importance in root canal therapy. Although determination of the root canal length through radiography is the most common method, recently electronic apex locators have been used to determine working length and decrease the number of radiographs. The purpose of this study was to compare the accuracy of an electronic apex locator (Root ZX) with conventional radiography to determine the working length (WL) of curved mandibular molars. Materials and methods:Thirty-five intact mandibular first molars with curve above 10 0 were selected. The access cavity was prepared and the root canal length was measured using apex locator and conventional radiography. Data were analyzed using the paired-sample t-test. Results:The working lengths measured by the apex locator were equal to the actual working lengths in 42.86%, 0.5-1 mm shorter in 31.43%, and 0.5 mm longer in 25.71%. The working lengths measured by radiography were equal to the actual working length in 51.14%, 0.5-1 mm shorter in 39.99%, and 0.5 mm longer in 2.86%. There was no significant difference between these two methods in the measurement of the working length (p = 0.951). Conclusion:The apex locator and conventional radiography were equally effective in determining the working length of the curved canals.

“…11 Electronic apex locator (EAL) can be safely used in patents with gag reflex, mentally retarded patient and pregnant patients as well. 12 However; Electronic Apex Locators have their own limitations. As they functioned with direct current, any interference especially fluid may lead to inaccurate result.…”

“…According to Rosenberg; "Paper point technique can provide more authentic details regarding the length and shape of root canal when compare to apex locator or digital radiograph as paper point can sometimes provide 3-dimentional details about location and slop of apical foramen." 12 To record WL by PPT we need a root canal free of its content and lack any moisture and vital tissues in periapical area. It could not assume that ppt is an alternate to other technique because it works as a part of other technique to establish WL.…”

Objective: The aim this study was to check the accuracy of paper point technique for final working length measurement after canal preparation. Study Design: Randomized controlled trial Place and Duration: Study was performed in department of operative dentistry, Liaquat University of Medical & Health Sciences, Jamshoro for one year duration from January 2017 to December 2017. Methodology: This study was performed on 78 patients divided equally into two groups. In one group working length was established by using electronic apex locator while in second group working length was established by using electronic apex locator with paper point technique. To check the working length master apical gutta percha point (GP point) was inserted into canal and radiograph were taken by paralleling angle technique. Results: There were 34 (43.6%) males while 44 (56.4%) patients were females. Mean age of patients was 30.5±8.9 years. Mean tooth number was 28.8±11.0. Group A is concerned that was treated only with Electronic Apex Locator showed lesser number of acceptable length than group B. on the other hand, group B was treated with electronic apex locator and paper point technique showed higher acceptable length of respondents with a difference of 4 frequencies or 7% in excess. A less value of chi-square test showed relationship between observed and expected data; whereas, significance value indicated no significant difference between group A and B. Conclusion: Paper point technique is as reliable as other techniques for final working length measurement. Key Words: Electronic Apex Locator, Paper Point Technique, Endodontic Working Length
