Research Progress on Smear Layer Removing Ability in Root Canals of Organic Acid Irrigation Solutions

Abstract

Abstract: A smear layer is produced during the instrumentation, which could be found both on the canal wall and into some dental tubules. Insufficient cleaning of the smear layer could result in failure of root canal therapy finally. Therefore, smear layer removing ability of root canal irrigation solutions had been researched by many scholars. Recently, one of the main root canal irrigation solutions for smear layer removal was organic acids and organic acid-based mixtures irrigation solutions. This article summarizes the current research progress on smear layer removing ability of organic acid irrigation solutions. It is suggested that the organic acid-based mixtures irrigation solutions, maleic acid, and tannic acid could be used the priority to remove the smear layer, which provides some reference for the clinic endodontic treatment.

Key words: root canal therapy, root canal irrigants, organic acid, smear layer
