Influence of glycolic acid as a chelating agent for smear layer removal and its effect on the microhardness of root canal dentin - A systematic review.

This study aimed to evaluate the effect of glycolic acid (GA) as a chelating agent on the removal of smear layers and the microhardness of root dentin. This review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and study quality was assessed using a modified Joanna Briggs Institute (JBI) tool. Two authors independently conducted an electronic search across four databases, supplemented by examining the reference lists of the included articles.
