A Triple-Blind Randomized Clinical Trial on Tooth Sensitivity and At-Home Bleaching
Study Overview
The study aimed to find out if a special gel can help reduce tooth sensitivity when using at-home bleaching treatments.
What Was Done
Thirty-two patients took part in the trial. They were divided into two groups:
- Desensitizing Gel Group: Received a gel with 3% potassium nitrate and 0.11% fluoride.
- Placebo Group: Received a gel with no active ingredients.
Patients applied the gel for 30 minutes before using a bleaching gel for 6 hours each night for three weeks. They recorded their tooth sensitivity daily on a scale from 1 to 5.
Key Findings
- Only 37.5% of those using the desensitizing gel reported sensitivity, compared to 87.5% in the placebo group.
- This shows a significant reduction in sensitivity risk (P < .05).
- In the first week, the placebo group reported more mild sensitivity, but no significant differences were seen in the following weeks (P > .05).
- Both groups had similar tooth whitening results throughout the trial, with no significant differences (P > .05).
Conclusions
The desensitizing gel effectively reduced sensitivity without affecting the whitening results from the at-home bleaching treatment.
