Title

Evaluation of the accuracy of different apex locators in determining the working length during root canal retreatment

Pages

  125-130

Abstract

 Background. This study aimed to assess the accuracy of three Electronic apex locators (EALs) (Dentaport ZX [J Morita, Tokyo, Japan], Propex Pixi [Dentsply Maillefer, Ballaigues, Switzerland], and iPex II [NSK, Tokyo, Japan]) during root canal Retreatment. Methods. The root canal lengths of 90 extracted single-rooted human teeth were determined under a dental operating microscope at ×10 magnification. The actual Working length (AWL) was 0. 5 mm less than the root length. Electronic measurements were performed with the three EALs. The root canals were instrumented and filled to the actual Working length using the lateral compaction technique. After seven days, the teeth were retreated until the Retreatment file was applied to the root canal at the Working length determined by EALs, and then, the three EALs were used for determining the Retreatment Working length. Data were analyzed using chi-squared and Kruskal– Wallis tests. Results. In the Retreatment, the accuracy of EALs was reported at %83. 3 for Dentaport ZX, %83. 4 for Propex Pixi, and %80 for iPex II within a tolerance of 0. 5± mm of the AWL. Conclusion. Under the limitations of this study, Dentaport ZX, Propex Pixi, and iPex II can be a useful adjunct during Retreatment. Clinicians should be aware that residual materials in the root canal during Retreatment can affect the accuracy of EALs.
