摘要：

The aim of this study was evaluate the demineralization caused on enamel by four different hydrogen peroxides used in dental bleaching. We obtained 20 teeth, which were divided into 4 groups. All teeth were initially evaluated to obtain the count of phosphorus and calcium elements interpreted from a range in X-Ray Fluorescence. After initial measurement, each sample was submitted to bleaching therapy according to the assigned group. Group 1 was treated with 35% manually mixed hydrogen peroxide, Group 2 with 35% auto-mixed calcium hydrogen peroxide, Group 3 with 35% auto-mixed hydrogen peroxide, and Group 4 with 38% auto-mixed hydrogen peroxide. The specimens were submitted to bleaching therapy during five weeks and were scanned every week. Before demineralization assessment, the bleaching gels pH was analyzed. The values for pH studied were not lower than the critical pH for demineralization and there were no statistical differences between the groups.
