ABSTRACT

Introduction: Accurate resolution of working length plays a vital role in endodontic therapy. Generally, the electronic apex locators are used more because of high accuracy and convenience when compared to other methods. As electronic apex locators (EAL) use the electronic method, it is possible that electromagnetic waves (EMW) affect their performance. Aim: to check the effect of electromagnetic waves on efficiency of electronic apex locator. Material and Methodology: the canal length of 10 maxillary incisors (vertucci type I) was measured with 15 k file. Root ZX mini and Apex ID locators were used to measure working length in a circuit of electromagnetic waves in both 2G and 3G mobile communication network at a distance of 40 cm. and in close contact with apex locators. Results: there is no significant change in measurement of readings when compared with mobile phone in different conditions (P > .05). Conclusion: the accuracy of the EALs (Root ZX mini or Apex ID) were not influenced when placed in direct contact with a smart phones of second and third generation.
