“…This study concluded that presence of root resorption in primary teeth did not affect the accuracy of WL measurement (p > .05) which was confirmed with the previous studies (Dandempally, Muppa, Duddu, Bhupatiraju, & Nallanchakrava, 2013;Taneja, Kumar, Sharma, & Gogia, 2017).…”

Electronic apex locators (EALs), cone-beam computed tomography (CBCT), and radiovisiography (RVG) claim to determine of working length (WL) in primary molar teeth. To evaluate the accuracy of WL determination by using three EALs, RVG, and CBCT imaging in extracted human primary molar teeth with/without root resorption. Twenty extracted primary molar teeth with resorption and 20 extracted primary molar teeth without resorption were used. After measuring actual lengths (AL) (Group 1), the electronic WL measurements were performed by using three different EALs [COXO C Smart-1 Pro (Group 2), iPex (Group 3), and Apex ID (Group 4)]. Two different image sets were obtained as follows: CBCT imaging (Group 5) and RVG (Group 6). AL measurements performed with an endodontic measuring ruler and compared with the EAL, CBCT, and RVG image measurements. For all groups, there were no significant differences between the teeth with resorption and without. There were no significant differences in measuring methods from AL and between the methods used (p > .05). When electronic and radiographic method were compared in different frequency ranges, there was no statistically significant difference (p > .05). This study showed that EALs, CBCT, and RVG have high accuracy in primary molar teeth both with resorption and without root resorption and can be used for determining WL.

“…17 Many in vitro [1][2][3]18 and other in vivo studies 10,11,19 sustain the potential use of electronic apex locators in primary teeth, regardless the stage of root resorption. 17 Many in vitro [1][2][3]18 and other in vivo studies 10,11,19 sustain the potential use of electronic apex locators in primary teeth, regardless the stage of root resorption.…”

“…Working length measurements by electronic apex locators are comparable with the conventional radiograph method in primary teeth pulpectomy. 17 Many in vitro [1][2][3]18 and other in vivo studies 10,11,19 sustain the potential use of electronic apex locators in primary teeth, regardless the stage of root resorption. The present in vivo study found that no difference was observed between both measurement methods, electronic and radiographic, when the palatal canal was measured in the maxillary teeth and when the distal canal was measured in the mandibular teeth.…”

Background Working length is an important step in primary teeth pulpectomy. Aim To evaluate whether there is a significant difference in the accuracy of electronic apex locators compared to the conventional radiography in working length measurements. Design Sixty‐four children (192 canals) between 5 and 9 years of age with indication for pulpectomy of a primary molar were included after eligibility criteria. A radiographic measurement was obtained from pre‐operative radiography from the cusp tip to the apex or resorption of the root. The electronic measurement was obtained from a complete measurement of the canal with an electronic device up to the apex. Data were analysed with Bland‐Altman plots and Wilcoxon test. Statistical significance was set at P ≤ .05. Results Statistically, there is not any significant difference between radiographic and electronic measurements for the palatal canal or distal canal, as well as mesiobuccal canals (P > .05). Statistically, there, however, is a significant difference between the measurements for the distobuccal canal and mesiolingual canal measurements (P < .05). High internal consistency for both radiographic and electronic methods was achieved (α ≅ 1). Conclusions Electronic and radiographic methods are similar in determining the length measurement of the root canals in primary teeth pulpectomies, except in distobuccal or mesiolingual canals.

“…Angwaranvong and Panitvisai 8 declared Apex locators in primary teeth 201 that AE0.5 mm is acceptable, whereas others 7,11,15,20,25 declared that AE1 mm is acceptable. Silva et al 23 26 found the accuracy 92%, and Dandempally et al 27 found the accuracy 87.33% for Raypex and 81.33% for IPEX. The results of in vivo studies made in primary teeth change in the range of 70-95.82%, and the results of the present study are comparable to other studies.…”

Formulating a regression equation for determination of working length in primary molars using apex locators: a clinical study

Abstract: Apex locators are reliable when compared with Ingles radiographic method and can enhance the safety of treatment in specific situations such as presence of root resorption. In case of non-availability of apex locators, the equations given in our study can be of use.
