ABSTRACT

OBJECTIVES: To examine the tooth whitening effects of a 3% hydrogen peroxide gel.METHODS: Twenty participants were given experimental tooth whitening gels containing 3% hydrogen peroxide, and another 20 participants, who served as the control group, were given tooth whitening gels that contained no hydrogen peroxide. Both groups used their respective whitening agents for 1 week, and tooth lightness was examined at baseline and 4 and 7 days after the experiment.RESULTS: Compared with the control group, in the experimental group, lightness values, determined using VITA classical A1-D4® and VITA SYSTEM 3D-MASTER®, were significantly increased after using the 3% hydrogen peroxide whitening agent (P < 0.01) both 5 and 7 days post-application (P < 0.05).CONCLUSIONS: The study findings confirmed that an improved tooth whitening effect could be expected with the use of a new type of whitening gel containing 3% hydrogen peroxide.
