EDTA (ethylenediaminetetraacetic acid) chelates calcium and other divalent cations in root surfaces to remove the smear layer and condition dentin for improved adhesion in endodontic and restorative procedures. Used for Root canal treatment and endodontic therapy — root surface conditioning prior to sealer and cement placement, Restorative dentistry — dentin conditioning to improve adhesion of bonding agents and composite resins.

Mechanism of action

EDTA is a chelating agent that binds to calcium ions in the mineralized tooth structure, dissolving the inorganic component of the smear layer created during root canal instrumentation. This demineralization exposes collagen fibrils and increases surface porosity, enhancing the penetration and adhesion of sealers, cements, and restorative materials to the root surface. The conditioning effect is reversible and time-dependent, typically requiring 1–10 minutes of application.
