Summary
This study found that a 6% hydrogen peroxide paint-on gel effectively whitens teeth. Both in-office and at-home applications by patients yielded significant clinical efficacy in tooth bleaching.
Area of Science:
- Dentistry
- Cosmetic Dentistry
- Dental Materials
Background:
- Over-the-counter (OTC) tooth whitening products are widely used.
- The efficacy of different application methods for 6% hydrogen peroxide paint-on gels requires further clinical evaluation.
Purpose of the Study:
- To compare the clinical efficacy of two tooth bleaching protocols using a 6% hydrogen peroxide paint-on gel.
- To assess efficacy after 1 and 2 weeks of treatment.
Main Methods:
- A randomized, single-blind, split-mouth clinical trial involving 16 patients.
- One hemi-arch received in-office application (Group I), while the other received daily at-home application by patients (Group II).
- Efficacy was measured using the Vita Classical shade guide at baseline, 1 week, and 2 weeks.
Main Results:
- Significant shade value improvements were observed in both the in-office and at-home treatment groups (P < .05).
- No statistically significant difference in tooth shade was found between the two application methods at the end of the treatment period.
Conclusions:
- The 6% hydrogen peroxide paint-on gel demonstrates significant clinical efficacy for tooth bleaching.
- Both clinician-applied and patient-applied methods achieve comparable and effective tooth whitening results.
