Lumineux Whitening Mouthwash and Strips Study
Study 1: OE strips A total of 5 extracted teeth were used. They were selected from 20 teeth which were all stained as per original protocol. For ease and translatability of comparison, 5 teeth with matching degrees of staining were selected for this study from the 20 stained samples. Tooth colors were measured by 1 experienced, blinded, pre-standardized examiner using standard colorimetry (as described in our previous study) and the Vita 3-D shade guide. Lighting was indirect and standardized and all measurements were repeated 3 times. At baseline, samples 1-3 had a shade of 3M2; samples 4 and 5 had a baseline shade of 2M1. After 10h treatment with OE strips, samples 1-3 lightened to shade 1M1. Samples 4 and 5 also lightened to shade 1M1.
Study 2: OE Mouthwash A total of 5 extracted teeth were used. They were selected from 20 teeth which were all stained as per original protocol. For ease and translatability of comparison, 5 teeth with matching degrees of staining were selected from the 20 stained samples. Tooth colors were measured by 1 experienced, blinded, pre-standardized examiner using standard colorimetry (as described in our previous study) and the Vita 3-D shade guide. Lighting was indirect and standardized and all measurements were repeated 3 times. At baseline, samples 6 and 7 teeth had a baseline shade of 4M1; samples 8-10 had a baseline shade of 3M2. After 48h treatment with OE mouthwash, teeth 6 and 7 lightened to shade 3M1. Samples 8-10 also lightened to shade 3M1.
Conclusion: The results of study 1 demonstrated that the OE whitening strip consistently lightens the shade of the teeth by up to 12 shades. Moreover, the results of study 2 confirmed that OE whitening mouthwash consistently lightens the shade of the teeth by up to 7 shades. Variables may include the color and micro anatomy of the existing teeth, as well as the cause of discoloration, and the application duration of the whitening agent.
