Evaluation of the effect of SmearOFF on Smear Layer Removal and Erosion of Root Canal Dentin
Background and Objectives: Root canal instrumentation produces a smear layer that covers the root canal walls and may have adverse effects on endodontic treatment.

Background and Objectives: Root canal instrumentation produces a smear layer that covers the root canal walls and may have adverse effects on endodontic treatment. SmearOFF is a new endodontic irrigant, which proposes smear layer removal and microbial elimination in one step. The aim of the present study was to evaluate and compare the effect of SmearOFF with other final irrigants regarding smear layer removal and degree of erosion from the apical third of root canals.
Methods: Forty mandibular premolar roots with single canals were selected. The teeth were randomly divided into 4 groups of 10 teeth each according to the type of final irrigants used during and after instrumentation: G1 6% NaOCl/ distilled water (control), G2 6% NaOCl/Qmix, G3 6% NaOCL/SmearOFF, G4 6% NaOCL/ 17% EDTA. All teeth were shaped by using ProTaper NEXT rotary system till X2. 6% NaOCl was applied with a 27-G side-vented syringe needle as an initial irrigant followed by the final irrigants. Endoultra ultrasonic device was used for irrigation activation. The samples were then submitted to scanning electron microscopy to evaluate the effectiveness of proposed treatments.
Results: In smear layer variables score 2 was the most occurred value for G2 (QMIX) and G3 (SmearOFF), whereas in G1 (Distilled water) and G4 (17% EDTA) are 3 and 1 respectively. For erosion variable, erosion was most evident in G4 (6% NaOCL/ 17% EDTA). There were no significant differences between G2 and G3 and also between G3 and G4 in both smear layers and erosion.
Conclusion: 17% EDTA, SmearOFF, and QMix using PUI can remove smear layer effectively from the apical third. In the future, SmearOFF may act as a promising chelating agent as well as an antimicrobial irrigant.
