Introduction: Determining the working length in root canal treatment is very important, since it allows clinical procedures to be performed within the anatomical limits of the canal. Objective: The aim of this article is to report five cases in which root canal treatment was performed by an electronic method without trans-operative radiographic verification. Methods: Three maxillary and two mandibular molars diagnosed with irreversible pulpitis or pulpal necrosis were treated at the Endodontic Clinic of the Military Regional Hospital of Guadalajara, Mexico. After obtaining patient’s informed consent, the working length of the root canal was measured with Raypex 6 apex locator, without radiographic verification. All root canals were prepared with Reciproc system instrumentation and filled by means of Tagger hybrid technique. Results: Postoperative radiographic control revealed that the level of root canal filling in 12 out of 14 root canals was from 0 to 2 mm of the radiographic apical apex. Conclusion: Results suggest that electronic conductometry is a reliable method to determine the working length. Additionally, it reduces the number of radiographs taken during root canal treatment.
