Visually, roots were examined under<br>stereomicroscope (X20) and the working length was determined using a size 15<br>K-file. The effect of Tenda Wi-Fi router on accuracy of electronic working length<br>measurement of electronic apex locator (iPex II) was determined in this study in<br>closed room under 5 conditions (without router and tablet, with router in different<br>distances 1 meter and 3 meters from electronic apex locator, with router and<br>connected with tablet in different distances 1 meter and 3 meters from electronic<br>apex locator). The electronic working length was measured 3 times per canal<br>under each condition. The data were compared using analysis of variance.<br>Results: The mean of working length measured under microscope was (13.30), and<br>the mean of working length by electronic apex locator was (13.14) while the mean<br>values of working length in different conditions was fixed (13.12). Analysis of<br>variance test (ANOVA) showed non-significant difference among working length<br>measurements in different conditions (P-value ≥ 0.05).<br>Conclusion: Within the limitations of the present study, stability and reliability of<br>iPex II apex locator in measurement of electronic working length where not<br>influenced when placed in (1M, 3M) from Wi-Fi router and active Tablet<br>(connected to network by Wi-Fi and streaming online videos). During root canal<br>therapy, active Tablet can be used in the dental operatory without the fear of<br>causing electromagnetic interference in electronic working length determination.<br><br></p>}, number={1}, journal={Mustansiria Dental Journal}, author={Hussein, Dr. Hashim M. and Saeed., Dr. Nooruldeen A. and Kudhair, Dr. Mantadher S.}, year={2018}, month={Dec.}, pages={8–15} }
