ABSTRACT
OBJECTIVES:
The purpose of this study was to evaluate the efficacy of a 2.9% hydrogen peroxide (HP) whitening strip with a desensitizing agent as a primer.METHODS:
This study was approved by the Institutional Review Board of Kyungpook National University Hospital. A total of 144 subjects (mean age 21.7 years) were recruited after they provided informed consent for participation in the study. All participants used the whitening strip and primer for 1.5 h a day for 14 days. ShadeEye-NCC and Vita classical shade guide were used to determine the color changes, with respect to baseline, after 1, 3, 5, 7, and 14 days. A self-administered questionnaire was used to collect data on satisfaction after bleaching and irritating symptoms during the 14 days. All collected data were analyzed with repeated measures ANOVA and one-way ANOVA using SPSS 20.0 for windows.RESULTS:
Brightness (ΔL*) was significantly higher in groups 2 and 3 than in the control group after 3 days of the experiment. Chroma (Δb*) started to decrease in groups 2 and 3, compared to control, after 1 day. Perceived symptoms of irritation were significantly lower in groups using the strip combined with the desensitizing primer than in the control group. Satisfaction after bleaching was higher in the experimental groups than in control.CONCLUSIONS:
The HP whitening strip with a desensitizing agent as a primer is clinically effective in bleaching human enamel after 3 days of use. It also reduces the prevalence of gingival irritation.
