ABSTRACT
Objectives: The aim of this study is to evaluate the microhardness of remineralized bleached surface subjected to erosion. Materials and methods: Fifteen samples were divided into three groups and subjected to bleaching and erosion treatment. Group I-treated with 30% hydrogen peroxide then treated with 1% citric acid solution; group II-treated with 30% hydrogen peroxide and a remineralizing agent followed by 1% citric acid solution; group III-without bleaching with 1% citric acid solution. Five samples per group, GI, GII, and GIII were subjected to the Vickers microhardness analysis. Loss of surface hardness loss (% SHL) was analyzed followed by one-way ANOVA test, post hoc multiple comparison test, Bonferroni test to compare the various group. Result: Group II showed the lowest % SHL after the erosive phase when compared with group I. Conclusion: Erosion which usually occurs as a consequence of bleaching can be minimized by the application of remineralizing agents after bleaching.
