In vitro study | 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 IC 50 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. |

biological activity | EGTA is a special calcium chelator. EGTA has a Kd of 7.4 nM at physiological pH (60.5), and has a high specificity for Ca2 than Mg2. EGTA significantly inhibited the substrate adhesion capacity of inflammatory macrophages. |
Use | is a calcium chelating agent, the effect of potassium salt is relatively better. |
