Comparative Study of the Expansive Behaviour of Different Internal Bleaching Agents

| description | Internal bleaching is a conservative treatment applied to a darkened endodontically treated tooth to restore its original colour, either as a single treatment or as a treatment prior to a subsequent prosthetic phase. The aim of this study was to objectively measure and compare using an experimental model the expansive capacity of four bleaching groups: carbamide peroxide 37% (CP 37%), hydrogen peroxide 30% (HP 30%), HP 30% mixed with sodium perborate (SP) and SP mixed with distilled water. A total of 150 lower incisors (<i>n</i> = 30 in each group) were prepared for the Walking Bleach technique and a glass tube with oil was introduced into the coronal access cavity to measure the expansive capacity through oil displacement, due to the reaction that occurs when bleaching agents interact with dental tissues. The results after 10 days were analysed with the Games–Howell post hoc test to compare the samples. Significant higher expansion was observed with HP 30% (<i>p</i> < 0.05) and lower expansion with SP (<i>p</i> < 0.05) compared to the other groups. No significant differences were observed between CP 37% (<i>p</i> > 0.05) and HP 30% + SP (<i>p</i> > 0.05). This provides significant and observable information on the behaviour of each bleaching group and its evolution after 10 days. |
