Effect of Smartwatch on Different Electronic Apex Locators on Working Length Determination: An In –Vivo Study

Abstract

Introduction: The user manuals of specific electronic apex locators (EALs) highlight that electromagnetic radiation can adversely affect their accuracy and functionality. In modern technology era, smartwatches are popularized among the younger generations as well as dentists and staff to monitor certain physical activities including cardiovascular activities and notifications which are directly displayed on smartwatch to avoid the uses of phone in between work. This study aimed to evaluate the impact of a smartwatch on the performance of two distinct apex locators in working length determination during root canal procedures.

Objectives: This study aims to assess effect of Smartwatch in Working length determination    using Root ZX-Mini and Endomotor Integrated apex locator i.e E –Connect S.

Methods: Thirty patients recommended for endodontic treatment on incisors, canines, premolars having a single canal and completely developed root apex were selected. K-file was being used to established working length using Root ZX mini (J-Morita) and E-connect S. A standard smartwatch, namely the Samsung Galaxy Fit 3, was utilized to estimate the impact of electromagnetic radiation on the precision of working length measurement. Measurements were conducted under the following clinical conditions: Root ZX mini and E-connect S with smartwatch and without smartwatch.

Results: There was no statistically significant variation in working length measurements between the two different apex locators, irrespective of whether a smartwatch was present (P > 0.05)

Conclusions: This study demonstrated that the presence of a smartwatch near an EAL does not significantly affect the accuracy of working length measurements obtained by two different apex locators.
