Title At Home Tooth Whitening Strips Are Most Likely As Effective As At-Home And In-Office Bleaching Treatments in Dental Patients
Clinical Question In dental patients, how effective are over-the-counter whitening strips compared to in-office bleaching and at-home bleaching techniques?
Clinical Bottom Line Vital teeth in dental patients seeking whitening procedures were whitened to the same degree when using home whitening strips and in-office whitening techniques. Data showed little to no difference between the outcomes of the two procedures. (See Comments on the CAT below)

Key resultsThis study compared three whitening techniques commonly used to whiten teeth; whitestrips, at-home bleaching (Opalescence PF 10%) and in-office bleaching (Opalescence Xtra Boost). Thirty-nine subjects participated in the study and 13 were randomly assigned to each category. Each treatment was used until it reached the goal of 6 grades of whitening according to the vita shade guide. The whitening strips group took an average of 31.85 +/- 6.63 treatment cycles to reach 6 shades of whitening. The at-home bleaching group took an average 7.15 +/- 1.86 treatment cycles to reach 6 shades of whitening. The in-office bleaching group took an average of 3.15 +/- 0.55 treatment cycles to reach 6 shades of whitening.

Comments on
The Evidence
Only one type of in-home and office type of bleach was used making it hard to generalize these results to all in-office or at-home products.
Applicability These results are relevant to those seeking the best means to whiten the shade of their teeth. The data suggests that the two procedures are equally effective in whitening teeth, but patients can save money by using the home whitening strips.

I conducted a PubMed search on this topic in April 2, 2012 and found more recent publications: PubMed ID 21037194. This RCT on 17 participants was conducted for 14 days and follow up at nine months. This study further strengthens the conclusions of this CAT.
