상아질 치관 치료를 위한 EDTA Na염의 킬레이션
The chelation of EDTA sodium salts solution for the root canal dentin treatment

초록
The demineralizing effect of chelating agents(Maleic acid solution, EDTA salts solutions; disodium-, trisodium- and tetrasodium-EDTA) on hydroxyapatite(HA) for the root canal dentin treatment was investigated. Dissolution of Ca from HA was increased with increasing immersion time in chelating solutions. Among the EDTA salts solutions, tetrasodium-EDTA was least effective in dissolving Ca out from HA, and trisodium-EDTA was the most effective. Trisodium-EDTA solutionmight be more effective in removing the smear layer compared to tetrasodium-EDTA solution.
