Comparative analysis of root surface smear layer removal by different etching modalities or erbium:yttrium–aluminum–garnet laser irradiation. A scanning electron microscopy study

Abstract: The purpose of this study was to evaluate the effect of erbium:yttrium-aluminum-garnet (Er:YAG) laser (2.94 mum) irradiation on the removal of root surface smear layer of extracted human teeth and to compare its efficacy with that of citric acid, ethylenediamine tetra-acetic acid (EDTA), or a gel containing a mixture of tetracycline hydrochloride (HCl) and citric acid, using scanning electron microscopy (SEM). Thirty human dentin specimens were randomly divided into six groups: G1 (control group), irrigated wi… Show more

“…It has the ability to remove the smear layer and also exert a potent antimicrobial activity. [11] This is the first study, which aim to use MTAD as a root biomodifier. The aim of the present in vitro SEM study was to comparatively evaluate the efficacy of MTAD (novel intracanal irrigant) and traditional root biomodifiers for smear layer removal and dentinal tubule opening on periodontally involved human teeth.…”

“…In vitro and in vivo papers have mixed results on the efficacy of smear layer removal, to enhance connective tissue attachments, with EDTA, HTCL, and citric acid application to the root surfaces [58]. In fact, Er:YAG laser and EDTA treated roots show similar micromorphology to each other [59,60].…”
