Abstract

|
|
Purpose: The aim of this clinical study was to evaluate the efficacy and safety of a self - applied paint - on whitening gel combined with wrap to increase the effect of a whitening gel and minimize gingival irritation.
Materials and Methods: Ninety adult volunteers were randomly treated to a control group and two experimental groups using whitening gel containing 2.8% and 3.0% hydrogen peroxide for 30 persons each. They had used the wrap and whitening gel on maxillary 4 anterior teeth for 30 minutes per day during 2 weeks. Whitening tooth color response was measured by VITA shade guide and ShadeEye NCC®. And side effects were assessed from interview and intraoral examination. The efficacy and safety evaluations were statistically analyzed.
Results: In the evaluation with VITA shade guide, there was significantly the whitening effect in experimental groups compared with the control group. In the evaluation with ShadeEye NCC®, the 3.0% experimental group showed significantly the whitening effect compared to the control group and the 2.8% experimental group (P < 0.05). There were some complaints of minor side effects, but there did not find abnormal symptoms of the gingival stimulation in all groups.
Conclusion: A self - applied paint - on whitening gel combined with wrap can be used as a useful self-whitening material because the whitening effect increases as the concentration of hydrogen peroxide from 2.8% to 3.0% and also no significant side effects are observed.
