Effect of different remineralization protocols on color change with two bleaching systems

Abstract

The purpose of this study was to investigate the effect of time of remineralization whether before, after, or before and after bleaching on the color change with fluoride-free and fluoride-containing bleaching agents.

A total of 56 permanent anterior bovine teeth were divided into two main group each of 28 teeth according to the bleaching material were used (Opalescence® Boost PF 40%, Whitesmile Power Whitening YF 40% HP) each main group was divided into 4 subgroups each of 7 teeth according to exposure to the different time of remineralization using Tooth Mousse® MI Paste® into; without application, before bleaching, after bleaching, before and after bleaching. Color measurement done by used Spectrophotometer VITA Easyshade Compact. Color change (∆E) was measured, tabulated and statistically analyzed. Results of color change (∆E) represented by mean and standard deviation (SD) showed that the application of different time of remineralization using Tooth Mousse® MI Paste® whether before , after and before and after bleaching had no significant effect on the color change (ΔE). On the other hand, using fluoride-free bleaching agent and fluoride-containing bleaching agents had no significant difference on the color change ∆E.
