Chemical influence of 30% hydrogen peroxide on an enamel surface

초록

Background/Objectives: This study sought to assess the morphological change in tooth bleaching when high concentrations of 30% hydrogen peroxide (H₂O₂) are used. Methods/Statistical analysis: A total of 20 extracted human teeth were sectioned and randomly grouped into two with 10 samples each. Group 1 as the control group without treatment and Group 2 treated with H₂O₂.After the bleaching treatment, distilled water was employed to wash all teeth, which were then dried using absorption paper. The surface particularities of bleached teeth with 30% H₂O₂ were analyzed using scanning electron microscopy (SEM) at 10 um. Findings: Based on the SEM observation result, the bleached enamel showed a marked difference in the control group, suggesting that inorganic components were affected. The enamel surfaces treated with 30% H₂O₂ differed from the surfaces of natural enamel. The morphological and microstructural changes manifested in the human enamel with high concentrations of 30% H₂O₂. The present in vitro study demonstrated the mineral distribution of enamel by application of high concentrations of H₂O₂. Improvements/Applications: The application of high concentrations of 30% H₂O₂ caused morphological and microstructural changes in the enamel surface. Demineralization effect was observed with tooth bleaching using 30% H₂O₂ treatment. © 2018, Institute of Advanced Scientific Research, Inc. All rights reserved.
