When root canals are instrumented during endodontic therapy, a layer of material com posed of dentine, remnants of pulp tissue and odontoblastic processes and bacteria is al waysformed on the canal walls. This layer has been called the smear layer. It has an amor phous, iregular and granular appearance under scanning electron microscope. The ad vantages and disadvantages of the presence of smear layer, and whether it should be re moved or not from the instrumented root canals, are still controversial. Once this layer is removed, it should be borne in mind that there is a risk of reinfecting dentinal tubules if the seal fails. Further studies are needed to establish the clinical importance of the ab sence or presence of smear layer. This article provides anoverview of the smear layer, fo cusing on its relevanceto endodontics. Con flictstill remains regarding the removal of thesmear layer before filling root canals, with investigationsrequired to determine the role of the smear layerin the outcomes of root canal treatment.
