Efficacy of removal calcium hydroxide dressing from root canals by Passive Ultrasonic Irrigation and Using a file one size larger than MAF


Abstract in English

Residual Calcium Hydroxide dressing on the root canal is considered one of the reasons of endodontic treatment failure. So ,the removal of this dressing completely before filling is required. The aim of the study was to evaluate the efficiencies of passive ultrasonic irrigation And increasing the instrumentation of the medicated canal to the file one size larger than MAF in removal of Calcium Hydroxide dressing.
