Two distinct apex locators' accuracy in estimating the working length in teeth with roots which are curved: an in vitro investigation

Original Research

Abstract

Aim

To determine how the tooth’s root canal curvature affects the apex locator's accuracy.

Materials and Methods

For the study, 20 human mandibular molars that had been extracted and whose mesial roots had a minimum 20-degree curvature were chosen. The teeth were mounted in alginate and then subjected to an accuracy test for locating each tooth's apex using the Root ZX and Propex Pixi apex locators.

Results

Working length determination done using Root ZX II showed more accurate length relative to the preoperative working length

Conclusion

Consequently, Root ZX (J MORITA, Japan) provided more precise results than Propex Pixi (Dentsply). has a difference that is significant at 0.05.
