Effect of Ultrasound on the Formation of Parachloroaniline Study in ex-vivo

Abstract

Background: The use of endodontic ultrasound (EUS) improves the irrigating properties of 5% NaOCl and its use on 2% CHX accelerates its degradation and production of parachloroanilina (PCA). The objective of this study was to quantify the PCA formed by the use EUS in an endodontic treatment using 5% NaClO and 2% CHX as irrigators.
