carbamide peroxide gel
Carbamide peroxide, hydrogen peroxide, and tray-delivered fluoride have been known to decrease plaque. With the decrease in plaque accumulation also comes a decrease in inflammation, decalcification, and the incidence of decay. Due to the common misconception that these materials must use custom delivery trays, orthodontic patients usually don't get to benefit from their use. Custom delivery trays used in an orthodontic patient could obstruct the planned movement of the teeth, or as the teeth moved, the trays would no longer fit. New delivery systems with prefilled, semi-custom, disposable trays address this problem.
Carbamide peroxide was introduced in the late 1960s as an oral antiseptic. It has been shown to be both safe and effective in reduction of plaque, inflammation, and decay.(1,2,3,4,5,6,7,8,9,10). Carbamide peroxide's whitening effects were discovered by accident in the late 1960s by an orthodontist (Klusmier) using removable appliances containing carbamide peroxide to improve the health of the gingival tissue. Its whitening effects were emphasized in an article in 1989 using a custom tray delivery system, and since then, carbamide peroxide's other benefits have been overshadowed.(11).
With all the benefits that carbamide peroxide, hydrogen peroxide, fluoride, and potassium nitrate together have to offer, there's no better recipient than the orthodontic patient. The delivery systems that provide all these materials in one disposable tray are Treswhite Classic and Treswhite Ortho (Ultradent Products, S. Jordan, UT). The prefilled, adaptable, disposable trays have a 5% carbamide peroxide gingival barrier and a 9% hydrogen peroxide gel in the tray with potassium nitrate and fluoride. These trays easily adapt to and around the orthodontic appliance. The patient wears each tray only 30 to 60 minutes per day due to the high concentration of bleaching agent. Nine percent hydrogen peroxide is approximately equal to 30% carbamide peroxide. Although the patient will benefit from the whitening effects of this high-concentration bleaching agent, the other benefits may not be as apparent because of the limited contact time. In order to increase contact time, the percentage of hydrogen peroxide would need to be lowered.
