Title Whitening at Home: Strips vs Gels
Clinical Question Are strips or gel varnishes more effective home whitening treatment for adults?
Clinical Bottom Line Strips bleached faster and more effectively than gel; both were surpassed by tray based overnight treatments. Of the whitening products on the market none show significant side effects but there is a need for more independent clinical trials due to current biases in research.

PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 12167948Niederman/20007 systematic clinical trialsMeta-Analysis
Key resultsWhitening products produced significant color change (p < 0.01), when compared to placebo control group (0.7 0.6, p > 0.05). However the brand of bleaching agent had a significant effect on tooth whitening, but the daily application time and duration of treatment did not.
#2) 19838560Demarco/200930 articlesSystematic Review
Key resultsThis article offers the best support and overall review of the current at home bleaching products available. Furthermore the bias of the paper appears to be minimal. The study was funded by the Brazilian Oral Research foundation and was also presented at an international symposium in 2008. Pertinent results: Gels produce a non-­clinically significant whitening effect. Whitening strips whiten similar to that of 10% CP in a tray. Independent, long-­term clinical trials are needed to evaluate the effectiveness, side effects and corrections to existing bias in current research.
#3) 17054282Hasson/2006416 articles were identified, 25 used Systematic Review
Key resultsWhile strips appear to whiten teeth more effectively than gels it is difficult to ascertain if the differences in efficacy is due to application method or concentration of active ingredients. There is need for long-­term pragmatic studies for evaluation of side effects.

Comments on
The Evidence
The three large and independent reviews appear to have come to similar conclusions on the efficacy of gels vs whitening strips although the statistical differences very. Article 19838560 provides the most comprehensive, complete and unbiased review of the majority of bleaching procedures available.
Applicability Over the years esthetics have become a larger and larger concern from dental patients. These results are relevant to those seeking to whiten the shade of their teeth at home. The data suggests that while both strips and gels appear to whiten teeth, strips have more visible results.
