Abstract


INTRODUCTION: Depending on the cause of discoloration, bleaching materials and other factors, vital dental bleaching techniques may be professional (in-office dental bleaching), at-home night-guard bleaching and combined.

The main objective of this study was to determine, in vitro, tooth color change using external dental bleaching techniques with 16% and 30% carbamide peroxide gel and to investigate the effect of concentration of carbamide peroxide gel on the bleaching success.

MATERIALS AND METHOD: This study included 20 extracted human intact teeth. The teeth were divided into two groups of ten teeth: the first group was bleached with 16% carbamide peroxide gel and the second group with 30% carbamide peroxide gel. The procedure was repeated three times for each tooth. The existing color of every tooth was recorded using VITA classical shade guide A1-D4 before treatment, after each session and after bleaching was completed.

RESULTS: Exact binomial test found a highly statistically significant difference (p <0.01) between the first and the second bleaching treatment, for both concentrataions. A statistically significant difference (p <0.05) was also present between the second and third treatments, while no statistically significant difference was found between the first and third bleaching treatments, for both concentrataions. χ2 test showed no statistical difference between groups based on degree of tooth shade change.

CONCLUSION: The teeth bleaching technique with 16% carbamide peroxide gel and the teeth bleaching technique with 30% carbamide peroxide gel have shown the same efficiency in tooth color changes.
