EDTA Irrigant 1 article

EDTA Irrigant is a chelating solution used in endodontics to remove the inorganic portion of the smear layer and soften mineralized dentin. It is commonly introduced after or during canal preparation to improve cleaning of prepared walls, assist negotiation of calcified anatomy and support a final irrigation sequence. EDTA does not provide the same tissue-dissolving action as sodium hypochlorite, so the two materials occupy different roles. Its identity is tied to dentin chelation and smear-layer management rather than to mechanical shaping.
