Observation of the Ultrastructural Changes of Sclerotic Dentin Pretreated with EDTA by SEM.

Abstract

Abstract: Objective: To evaluate the ultrastructure changes of sclerotic dentin in non-carious cervical lesions before and after pretreated with EDTA(Ethylene Diamine Tetraacetic Acid). Methods: 10 teeth with scale Ⅲ or Ⅳ sclerotic dentin were selected. The ultrastructural changes of them before and after pretreated with EDTA were observed by SEM. Rusults: After pretreated the sclerotic dentin by EDTA, the top dentinal tubules of the calcium salt deposits were completely dissolved, and there still has residual dissolved calcium salt particle in the deep dentinal tubules. Conclusion: EDTA could improve the poor adhesion of the sclerotic dentin surface and increase the bond strength.

Key words: Sclerotic dentin, EDTA, SEM
