Complete removal of endodontic obturation materials and remnant from the root canal is the key to Endodontic retreatment success however no single method has shown to achieve this purpose so far. The aim of this study is to evaluate the efficacy of ultrasonic activation solvent as final irrigant in removal of residual obturation materials during endodontic retreatment procedure using protaper universal retreatment system. Using digital microscope and Scanning electron microscope SEM. forty lower premolars were selected and divided into five groups of 8 one control group without solvent the other groups were divided according to the solvent and the ultrasonic activation G1: without solvent, G2 orange oil without ultrasonic activation, G3 orange oil with ultrasonic activation, G4 chloroform without ultrasonic activation, G5 chloroform with ultrasonic activation. After retreatment the ro.. Read More»
