The Effect of Smear Layer Removal on Endodontic Outcomes

Abstract

A layer of organic and inorganic debris referred to as the smear layer is produced during mechanical instrumentation of root canal system. Effectively removing this layer is accomplished with the use of Ethylenediaminetetraacetic acid (EDTA) and sodium hypochlorite (NaOCl). Recommendation to remove or retain the smear layer has not been supported based on a controlled outcome study. This remains a topic of discussion within the endodontic community. This randomized, prospective, double-blinded clinical trial compared the outcomes of teeth in two groups; which either had the smear layer removed or where the smear layer was left intact. Covariate factors and the possible influence on outcomes was analyzed.
