Title |
Comparison Of Products Used For Intracoronal Bleaching |
Clinical Question |
In a patient with a nonvital tooth, will internal tooth bleaching using sodium perborate and 37% carbamide peroxide paste produce as effective whitening in the same length of time as sodium perborate and distilled water? |
Clinical Bottom Line |
In a patient with a non-vital tooth, intracoronal bleaching with sodium perborate and 37% carbamide peroxide paste produces the same shade of white in the same length of time as sodium perborate and distilled water. (See Comments on the CAT below) |

#1) 19071038 | de Souza-Zaroni/2009 | 30 patients desiring intracoronal bleaching | Randomized Controlled Trial | Key results | In the group bleached with sodium perborate and 37% carbamide peroxide paste, the pre-treatment mean color position was 15.07 and post treatment mean color position was 9.27. The group treated with sodium perborate and distilled water had a pre-treatment mean color position of 15.13 and post treatment mean color position of 9.67. The Wilcoxon paired signed rank test verified that both groups presented significant difference in pre and post-treatment color (P = .007 for both groups). The Mann-Whitney test showed that there was no significant difference between the two groups when comparing the change in color position (P =1). | |

Comments on
The Evidence |
This was an RCT with similar groups at the start, >80% completion rate, groups were treated the same, had adequate followup, double blind, unlikely recall bias, and no competing interests. |
Applicability |
Harms: Intracoronal bleaching with 35% carbamide peroxide gel results in hydrogen peroxide diffusion into the periradicular area. 30%-35% Hydrogen peroxide has been linked to external resorption. The bleaching agent containing distilled water instead of carbamide peroxide is therefore potentially less damaging. |
