Abstract
Background: Tooth whitening is a widely used aesthetic technique; however, some bleaching agents can affect enamel adhesive strength. There is interest in determining the effects of ozone and hydrogen peroxide, with and without calcium, on this property. Purpose: To evaluate the differences in enamel adhesive strength in bovine teeth subjected to tooth whitening with ozone, hydrogen peroxide with calcium, and hydrogen peroxide without calcium. Methods: An experimental study with an in vitrodesign was used. 75 bovine lower anterior incisors were divided into three groups (n=25 per group). The respective bleaching treatments were applied, and adhesive strength was measured using a digital universal testing machine at a speed of 0.5 mm/min. Measurements were taken at 24 hours, 7, 14, and 21 days after treatment. Data were analyzed using ANOVA and Tukey's post hoctest. Results: Statistically significant differences were observed between groups at 24 hours (p = 0.0044) and 7 days (p = 0.0026). The highest adhesive strength was recorded with 35% hydrogen peroxide with calcium at 21 days (11.50 ± 2.27 MPa). In all three groups, strength progressively increased over time. Conclusion: The type of bleaching agent and the time elapsed after treatment influence the adhesive strength of the enamel. Hydrogen peroxide with calcium showed the best performance at 21 days.
