Efficacy and Safety Assessment of Experimental Bleaching Agents

Sponsor: University of Oklahoma

View on ClinicalTrials.gov

Summary

Tooth bleaching is widely used to treat the colors of teeth. This study compares the efficiency of two experimental bleaching gels, with and without nanoparticles, and with and without light activation versus two commercial bleaching products of low and high concentrations. The objective is to evaluate tooth color change, sensitivity, and patient satisfaction in patients with moderate yellowing of their teeth. Methods: This is a randomized controlled trial that will include 120 participants aged 18-65 years. Participants will be randomly assigned to one of 12 treatment groups: Gel A (with or without nanoparticles, with or without light), Gel B (with or without nanoparticles, with or without light), Whiteness HP 35% (with or without light) and Whiteness Automixx 6% (with or without light). The primary outcome is tooth color change, measured using a commercially-available equipment. Secondary outcomes will include tooth sensitivity and patient satisfaction. Randomization will be computer-generated. Results: The study is expected to show differences in color change between the experimental and commercial gels. Tooth sensitivity and patient satisfaction will be evaluated to determine the overall effectiveness and safety of the treatments. Conclusions: This trial will provide information into the whitening efficacy of two experimental gels compared to two widely used commercial products.
