Clinical evaluation of chemical and light-activated tooth whitening systems

Gerard Kugel et al. Compend Contin Educ Dent. 2006 Jan.

Abstract

Tooth whitening has become one of the most popular dental treatments available. This article compares the efficacy of 2 in-office whitening systems using a split-arch, randomized, parallel, blinded clinical evaluation study. Both in-office tooth whitening systems were effective and there was no significant statistical difference over the 2-week period of observation. The use of light did not demonstrate any benefit over the chemically activated tooth whitening system after a 2-week recall.
