“…Electronic apical locators are very important devices in Endodontics. When compared with radiography, EAL decreases exposure to radiation and determines the position of the apical constriction or apical foramen, rather than of the radiographic apex (Bernardes et al 2021;Abidi et al 2020). Some authors, following manufacturers' instructions, and using methods similar to those adopted in this study, analyzed the accuracy of EALs in locating apical constriction, or a distance 0.5mm short of the apical foramen (Piasecki et al 2016;Connert et al 2018;Serna-Peña et al 2020).…”

Objective: To evaluate the effect of 2% chlorhexidine (CHX) and 2.5% sodium hypochlorite (NaOCl) on the accuracy and repeatability of three Electronic Apex Locators (EALs). Methodology: Thirty one human teeth were connected to a platform, irrigated with 2.0% CHX, and obtained two readings, again irrigated with 2.5% NaOCl and obtained two more readings. The distance between the tip of the file and the apical constriction was measured. Repeatability was calculated using the intraclass correlation coefficient (ICC) and repeatability coefficient (CR). Results: For CHX 2%, with the Mini Apex Locator, 25 of 31 electronic measurements were accurate (80.6%), 28 of 31 measurements for iPex (90.3%) and for Root ZX II 26 (83, 9%). For 2.5% NaOCl, with the Mini Apex Locator, 25 of the 31 measurements were accurate (80.6%), 28 of the 31 measurements for the iPex (90.3%) and for the Root ZX II, 24 (77, 4%). There were no differences between the two irrigants (p>0.05). The values (ICC) were 0.975 and 0.994 for the Mini Apex Locator, 0.981 and 0.971 for the i Pex and 0.994 and 0.995 for the Root ZX II. When using CHX, the (CR) was 0.196 for the Mini Apex Locator, 0.152 for the iPex and 0.088 for the Root ZX II. When using 2.5% NaOCl, the (CR) was 0.088 for the Mini Apex Locator, 0.196 for the iPex and 0.088 for the Root ZX II. Conclusions: The use of 2% CHX and 2.5% NaOCl did not affect the accuracy and repeatability of the three devices.

“…[ 16 17 18 ] The use of endodontic motors with EAL together presents the advantage of monitoring the WL during root canal preparation, and previous studies reported their suitable accuracy for WL determination[ 19 20 21 ] being that in some cases showed better accuracy than to conventional radiographic method.

“…Electronic apex locators (EALs) used to determine root canal length were first described by Suzuki in 1942[ 4 ] and introduced clinically by Sunada in 1965. [ 5 ] In vitro and in vivo studies showed good accuracy of these devices in determining root canal length,[ 6 7 8 9 ] although some authors report that the anatomical diameter of the apical foramen,[ 10 ] instrument's tip diameter and kind of alloy could interfere in measurements.

Influence of heat treatment of nickel–titanium instruments on the accuracy of an electronic apex locator integrated with endodontic motor

et al. 2022

Context: Manufacturers have produced a wide variety of nickel–titanium (NiTi) alloys, but the available literature is limited on the accuracy of some integrated electronic apex locators (EAL) used with different NiTi heat treatments in working length (WL) determination. Aim: This study aims to evaluate ex vivo , the influence of different heat treatments of NiTi instruments, and the diameter of the apical preparation on the accuracy of an EAL used during root canal preparation using an integrated EAL and motor unit. Materials and Methods: Nineteen extracted human mandibular incisors were included in the study. The WL control was determined by the visual method. Instruments of Mtwo, Reciproc, Reciproc Blue, WaveOne Gold, Twisted File Adaptive, and Hyflex CM systems, with diameters from 0.25 mm to 0.50 mm, were used to measure WL during root canal preparation. The electrical resistivity of instruments with a diameter of 0.25 mm from each system was evaluated using an Inductance, Capacitance, and Resistance (LCR) meter. Statistical Analysis Used: Data were statistically analyzed using Fisher's exact test and Kruskal–Wallis test. Results: The different heat treatments and different diameters did not influence the precision of the EAL ( P > 0.05). Conclusion: The heat treatment and the diameter of the apical preparation did not influence the accuracy of WL determination by an EAL integrated with the endodontic motor.

Objetivo: Realizar uma revisão dos principais artigos encontrados na literatura acerca do uso dos Localizadores Eletrônicos Foraminais (LEF) em dentes decíduos e representar através de um relato de caso clínico, a importância do uso destes dispositivos durante o tratamento endodôntico em dentes decíduos. Revisão da literatura: Foi realizada uma busca nas principais bases de dados, e selecionados 13 artigos considerados mais relevantes. Todos os estudos mostraram que a determinação da odontometria em dentes decíduos utilizando o LEF é bastante segura e com boa acurácia, podendo ser utilizado o localizador para esta finalidade. Relato do caso: No caso clínico apresentado, o uso do LEF foi fundamental para a obtenção de uma odontometria precisa, além da diminuição do tempo de cadeira e identificar reabsorções não detectáveis radiograficamente. O caso foi conduzido em duas sessões, onde na primeira foi realizada a cirurgia de acesso, odontometria eletrônica, preparo manual dos canais e utilização de medicação intracanal de hidróxido de cálcio. Na segunda sessão foi removida a medicação intracanal e os canais foram obturados utilizando pasta iodoformada. Discussão: O uso do LEF no tratamento endodôntico de dentes decíduos tem se mostrado uma ferramenta segura e eficiente, tendo melhor performance na determinação do comprimento de trabalho quando comparado a outros métodos. Conclusão: De acordo com os estudos apresentados na revisão de literatura e o caso clínico apresentado, pudemos constatar que o uso do LEF contribui positivamente ao tratamento, principalmente quanto ao ganho de tempo e determinação confiável e segura do comprimento de trabalho.
