A study published in the Journal of Clinical Dentistry has shown that Nu Radiance Forté Teeth Whitener promotes the remineralization and recalcification of teeth during the whitening process. The study demonstrated that Forté recalcified incipient lesions to clinically significant depths (100 µm) and improved the surface hardness of the enamel. The studies were performed under the direction of Bruce R. Schemehorn at Dental Products Testing, Indiana University Emerging Technologies Center in Indianapolis. The tests, which simulated in vivo conditions, showed significant uptake of calcium (more than 10% increase) and corresponding increases in surface hardness when using Forté calcium peroxide whitening agent, compared to a nonwhitening control (saliva). These results compared favorably with the losses of calcium and decreased enamel surface hard-ness reported in studies of many conventional whitening agents. The Nu Radiance Forté Whitening System is a dentist-provided, tray-based, take-home whit-ening product that uses calcium peroxide to boost the whitening effect while providing calcium compounds at a healthy high pH to remineralize the teeth and to reduce the dentinal fluid flow, a major cause of tooth sensitivity. A catalyzed 30-minute whitener, Forté uses a dual-barrel syringe to dispense freshly mixed gel, a combination of 14% calcium peroxide and 30% carbamide peroxide, at each application.
