The purpose of this double-blind in vivo study was to evaluate the efficacy of 44 percent carbamide peroxide, or CP, and 16 percent hydrogen peroxide, or CP, during daytime use, and less than 1-hour utilizing a standard LED light operating in the broad spectrum of Nanometers.

Patients mouths were divided into quadrants with the upper right quadrant using the Brite XL3, the lower right using the I-Brite, the upper left using the Aladdin Wireless Light, and the lower left using Beyond Dental Light.
