MACHADO, Ricardo et al. Use of electronic apex locator in the impossibility of radiographic visualization of the root apex: report of two cases. RSBO (Online) [online]. 2013, vol.10, n.4, pp. 402-406. ISSN 1984-5685.
Introduction: Electronic apex locators have been widely used for foraminal identification and for working length determination. The establishment of a correct apical limit is essential for a good prognosis in cases of pulp vitality or pulp infection. Objective and Case reports: The aim of the study is to report two cases where the use of electronic apex locators was crucial due to the inability to visualize the root apex due to a post-surgical retaining plate (case 1) and during orthodontic treatment with a maxillary expander (case 2). Conclusion: In this light we could confirm the effectiveness of these devices for the determination of the working length when it is impossible to perform it by radiographic techniques.
