简要总结

The aim of the present study was to evaluate colorimetric changes and tooth sensitivity in young patients submitted to tooth bleaching with 20% and 35% hydrogen peroxide.

详细描述

A randomized, controlled, clinical trial was conducted with 53 patients aged 11 to 24 years who were allocated to groups based on the use of the following commercial products: Whiteness HP - FGM® (35% hydrogen peroxide); Whiteness HP Blue Calcium - FGM® (35% hydrogen peroxide); and Whiteness HP Blue Calcium - FGM® (20% hydrogen peroxide).

After the bleaching procedure, the visual analog scale was used to measure tooth sensitivity and the classic Vita® scale was used to determine changes in tooth color.

Statistical analysis involved the Friedman, Kruskal-Wallis and Student-Newman-Keuls tests, with p-value ≤ 0.05 or ≤ 0.0001 considered indicative of statistical significance.

结局指标

主要结局

Discoloration

时间窗: Change of teeth color after 48 hours, after 6 months, after 12 months, after 18 months

the initial tooth color was determined with the aid of the classic Vita® scale. Tooth color was recorded 48 hours after each session to determine the difference in tone before and after the procedures. It will be carried out in all groups at the following times: pre-treatment period, 48 hours following each session, after six months, after 12 months, after 18 months.

次要结局

  • Dental sensitivity(Sensivity alteration up to 48 hours after the procedure)
