Clinical evaluation of a novel whitening gel, containing 6% hydrogen peroxide and a standard fluoride toothpaste.

Objectives: The aim of this study was to determine the effect on tooth colour (after 1 and 2 weeks use) of a self-applied tooth-whitening gel containing 6% hydrogen peroxide using a novel applicator, compared to a standard fluoride toothpaste.

Methods: A 2-week, examiner-blind, stratified, parallel design clinical trial was conducted. Efficacy was measured by comparing the Vita shade scores recorded at baseline and after 1 and 2 weeks of product application.
