Comparison of the Whitening Effects of Three Commercial OTC Products
† Mean score ±standard deviation, n =6. Values in the same column with the same superscript letter are not statistically different, while those with different superscript letters are different at p<0.05 based on ANOVA.
Results: There was statistically significant change when looking at ΔE after only 40 minutes (20 treatments x 2 minutes) of contact time with the Luster Premium White vs. 80 minutes (4 treatments x 20 minutes) of contact time with Rembrandt 2 Hour and 120 minutes (4 treatments x 30 minutes) with Crest Advanced 2 Hour. The overall change in stain was calculated using the CIELAB equation ΔE=[(ΔL*)2+(Δa*)2+(Δb*)2]1/2
Conclusions: In this In-Vitro evaluation, Luster Power White™ significantly increased overall whitening (ΔE) compared to Rembrandt® 2 Hr Whitening and Crest 3D White Whitestrips® - Advanced Seal®, with 1/3 to 1/2 the contact time.
