“…The theory states that the impedance between the oral mucosa and the periodontal membrane is always constant, regardless of their positions, and that it is not influenced by a patient's age, type of tooth or sex [5].…”

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.

“…Feeling the apex with an instrument (tactile) requires skill, experience and cannot be considered absolutely accurate. Various electronic devices used to measure the exact length of the root canal have been introduced into the endodontic practice in the last few years [1][2][3][4][5]. The odontometer is one such device which identifies different tissues of the tooth and surrounding structures depending upon difference in their electrical impedance.…”

The measurement of root canal length is a pre-requisite for successful pulpectomy. The conventional manual and radiographic methods are not very accurate. In the present study. odontometer was used (Group B) to assess its efficacy over the conventional methods (Group A) for recording root canal length. In group A, 36 teeth were treated with pulpectomy while in group H, 51 teeth were managed by the same treatment. It was observed that post operative complications in group B were significantly less (p < 0.05). The odontometer proved to be an excellent device for rapid and accurate measurement of root canal length. MJAFI 1994; 50 : 181-184
