Evaluating a desensitizer for tooth sensitivity after bleaching

Assessment of the Effects of Bio-active Desensitizing Materials on the Bleaching Efficacy and Reduction of Tooth Sensitivity Caused by Vital In-office Bleaching: A Randomized Controlled Clinical Trial

Not applicable Interventional King Abdullah University Hospital · NCT06532526

This study is testing if a special gel can help reduce tooth sensitivity after professional teeth whitening compared to a fluoride gel and a placebo.

What this trial studies

This clinical trial aims to assess the effectiveness of a bioactive glass desensitizer in reducing tooth sensitivity that occurs after in-office vital tooth bleaching. Participants will be randomly assigned to receive either the bioactive desensitizer, a fluoride gel, or a placebo gel without desensitizing agents. The study will measure the incidence, intensity, and duration of tooth sensitivity, as well as the impact on tooth shade following the bleaching process. The trial will be double-blinded to ensure unbiased results.

Who should consider this trial

Good fit: Ideal candidates are healthy individuals aged 18 to 30 with at least eight maxillary anterior teeth that are C2 shade or darker and no history of tooth sensitivity.

Not a fit: Patients with active caries, periodontal diseases, or those who have previously undergone tooth bleaching may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective way to manage tooth sensitivity for patients undergoing in-office bleaching procedures.

How similar studies have performed: Other studies have shown varying degrees of success with desensitizing agents in dental procedures, but this specific approach using a bioactive glass desensitizer is relatively novel.
