Evaluation of Smear Layer Removal and Micro Hardness Alteration of Radicular Dentin after Using Various Chelating Agents - An Atomic Force Microscopic Study.

Background And Aims: For endodontic therapy to be successful, the smear layer produced by the root canal instruments must be removed. The study's objective is to evaluate the effectiveness of radicular dentin microhardness modification and smear layer removal utilizing various chelating agents.

Materials And Methods: Extracted human mandibular single-rooted premolar teeth were selected for the study.
