Abstract

Introduction: Tooth whitening is a widely prescribed procedure in dentistry, although its adverse effect is tooth sensitivity. Objective: To evaluate the effect of ozonized oil associated with low-power laser in the treatment of tooth sensitivity and the degree tooth whitening. Methodology: A clinical trial split-mouth with a consisted of 30 volunteers randomized into 2 experimental groups (n=30). Control: application of potassium nitrate for 10 minutes; Test: application of ozonized sunflower oil for 2 minutes. Both arches were then bleached with 35% hydrogen peroxide for 45 minutes. After, a low-power laser was applied at infrared wavelength (808nm), 1J/cm² to the cervical region of the tooth and to the region corresponding to the root apex in both groups. The sensitivity data was analyzed using Friedman's repeated measures ANOVA test, followed by the Durbin-Conover post hoc test (p < 0.05) and the Wilcoxon test (p < 0.05). The Wilcoxon test (p < 0.05) and the Mann- Whitney test (p < 0.05) for evaluation degree of whitening. Results: There was no statistically significant difference in the intergroup analysis for the degree of whitening and sensitivity. Conclusion: The use of a combination of ozonated oil and low-power laser had similar results with control group.
