The Venus White Pro at-home teeth-whitening system whitens teeth up to 8.4 shades with virtually no sensitivity, according to a study conducted by researchers at the University of Texas Health Science Center at Houston in collaboration with Heraeus Kulzer.
The results of the study will be presented next month during the International Association for Dental Research (IADR) meeting in San Diego, the company said.
The study was designed to evaluate the efficacy and color rebound effect of commercially available 22% carbamide peroxide Venus White Proat-home teeth-whitening system. The study also evaluated the sensitivity of Venus White Pro.
A random selection of patient participants with no history of previous tooth whitening was recruited for the study. Subjects were treated nightly for two weeks with a maxillary custom tray containing Venus White Prowith 22% carbamide peroxide and 3% potassium nitrate.
Visual and instrumental measurements evaluation conclusively showed clinical whitening up to 8.4 times one week post bleaching, the researchers found. In general, color stabilized at two weeks postbleaching.
On the sensitivity test, patients reported very low sensitivity levels with a mean value of "below 2" on a scale of 0 to 10, with zero representing no pain and 10 representing worst possible pain.
