Lumineux Whitening Strips Gingival Irritation Study
Aims: The aim of this study was to evaluate the in-vivo effects of a novel whitening strip on tooth sensitivity and gingival irritation.
Methods: A total of 10 participants were recruited to apply one brand of whitening strips to the upper-left and lower-right quadrants of the mouth and the other brand to the remaining teeth. The strips were applied daily for 30 minutes over 10 consecutive days. Tooth sensitivity and gingival irritation were evaluated for each tooth at baseline, Day 5, and Day 10 by a blinded clinician.
A three-second air-spray test was applied to each isolated tooth to semi-quantify sensitivity using a Likert scale from 0 to 4. Visual inspection was also performed to identify gingival irritation on a scale from 0 to 3. Each participant completed a questionnaire daily after each whitening treatment and documented dental sensitivity and gingival irritation for each tooth. Data were analyzed using ANOVA techniques.
Results: For the office-based evaluations, significantly lower gingival irritation resulted from use of the test Oral EssentialsR whitening strips compared to the control 3D CrestR strips. Patient self-evaluations recorded lower gingival irritation, although not at a significant level, after the use of the test strips compared to the control strips. Dental sensitivity was comparable in the two treatment groups as evaluated in home and in the dental office.
Conclusion: Use of a novel tooth whitening strip resulted in less gingival irritation compared with a widely used control whitening strip.
