Title |
Comparing The Application Method Of Different Peroxide-Containing Tooth Whitening Systems |
Clinical Question |
In patients with discolored teeth, does undergoing at-home tooth whitening with bleaching trays, compared to using over-the-counter bleaching systems, experience a more esthetic result? |
Clinical Bottom Line |
The findings in these short term studies are significant as the custom tray group experienced on average greater color improvement compared to either the paint-on gel or activated peroxide whitening dentifrice, differing significantly (p< 0.01) from either of the barrier-free systems.

#1) 15794456 | Gerlach/2004 | 43 adults | Randomized Controlled Trial | Key results | The custom tray group experienced a significantly better color improvement (p< 0.01)compared to either the paint-on gel or activated peroxide whitening dentifrice that did not experience a significantly different color change (p< 0.10). Tooth sensitivity and oral irritation were the most common side effects in the tray and dentifrice groups, but there were no side effects in the paint-on group. | #2) 17054282 | Hasson/2006 | 25 articles | Systematic Review | Key results | “Strips (5.5% to 6.5% hydrogen peroxide(HP)) are more effective than gel in tray at 10% carbamide peroxide (CP) mean difference 1.82 (95% confidence interval (CI) 0.26 to 3.38)” quoted from Weyant Results. | |

Comments on
The Evidence |
Studies used in the systematic review used short term follow-up periods and were supported by manufacturers of the products tested. Independent long term studies are needed to clarify the long term effectiveness of these procedures. |
Applicability |
Using a barrier-based tray system for tooth whitening provides superior tooth color enhancement compared to other barrier-free over-the-counter whitening systems. |

by Emily Moers (San Antonio, TX) on 04/24/2012 After a similar evidence search, a more recent article in the American Journal of Dentistry, 2007, reiterated the above key findings. PMID: 17993029
randomized control trial or 87 adults found 6% hydrogen peroxide whitening strips significantly whitened teeth compared to whitening gel and placebo. | |
