EGTA is a specific calcium ion chelator. EGTA has an apparent calcium dissociation constant (Kd) of 60.5 nM at physiological pH (7.4) and has very high specificity for Ca2+ over Mg2+ (Mg2+ Kd 1-10 mM). EGTA significantly inhibited the substrate adherence capacity of inflammatory macrophages[1][2].

Description	EGTA is a specific calcium ion chelator. EGTA has an apparent calcium dissociation constant (Kd) of 60.5 nM at physiological pH (7.4) and has very high specificity for Ca2+ over Mg2+ (Mg2+ Kd 1-10 mM). EGTA significantly inhibited the substrate adherence capacity of inflammatory macrophages[1][2].

In Vitro	EGTA, proposed as endodontic irrigant, decreases substrate adherence capacity of inflammatory macrophages in a time- and dose-dependent manner. The EGTA concentration that causes an IC50 is 202 mM. Chelators react with calcium ions in the hydroxyapatite crystals to produce a metallic chelate. Removal of calcium ions from the dentine makes the dentinal tissue softer, especially the hydroxyapatite-rich peritubular dentin and increases the diameter of exposed dentinal tubules[2].
