Abstract

Introduction: Radiography is the most common method for measurement of WORKING LENGTH, but it is not the ideal method. The application of radiography in children is more dangerous and difficult in respect to radiation hazard, technical problems, superimposition of permanent teeth bud on PRIMARY TEETH, and so on. ELECTRONIC APEX LOCATOR (EAL) is a device for determination of WORKING LENGTH. In the present study, we evaluated the in vitro accuracy of EAL in Measuring resorbed root canal length in PRIMARY TEETH.Materials & Methods: This analytical-descriptive study was conducted on 112 canals of extracted PRIMARY TEETH that had at least 2.3 of root length. After preparation of the access cavity and removing pulp chamber tissue, the lengths of the canals were measured by Dentaport ZX and the real length of the canals were determined straightly with 0.5 mm accuracy. Then two measurements were compared. Data were analyzed by paired T test and intra class correlation and p<0.05 was considered as the limit of significance.Results: The accuracy of Dentaport ZX for carefully determination of apical foramen was 52.7% and in the range of -0.5 to +0.5 mm from apical foramen was 91.1%. There were a straight powerful linear correlation between measurements by eye and Dentaport ZX.Conclusion: According to the results of this study, using Dentaport ZX in ENDODONTIC TREATMENT for PRIMARY TEETH especially for non-cooperative children is recommended.
