Effect of Ozonized Water on Dentin Micro Hardness of Human Teeth.

Abstract

Abstract: Objective: To study the effect of ozonized water as endodontic irrigation solvents on dentin micro-hardness of human teeth. Methods: Extracted human premolar crowns were cut along long axis and treated with 2.15mg/L ozonized water, 1%NaOCL, 3%H2O2, 15%EDTA and distilled water respectively for 5min and 15min. The micro hardness of dentin was measured. Results: 1%NaOCL, 3%H₂O₂ and 15%EDTA decreased the micro hardness of dentin, especially 15%EDTA, while ozonized water was harmless to dentin micro hardness. Conclusion: It is recommended to apply 2.15mg/L ozonized water as endodontic irrigation.

Key words: Ozonized water, Endodontic irrigation solvents , Dentin , Micro hardness
