Abstract

The smear layer is a thin layer of tooth tissue, bacteria and infected dentine that is intimately attached to the wall of root canals. It is created during any instrumentation of the root canal and inhibits microbe removal from dentine tubules and intimate attachment of endodontic sealer, which necessitates its removal. A variety of materials for removal of the smear layer is available: this article discusses the different types and makes general recommendations on the treatment of the smear layer and the use of chelating agents in endodontic treatment. CPD/Clinical Relevance: Removal of the smear layer is necessary for thorough disinfection of the root canal system and for the predictable healing of apical periodontitis.
