Summary

Background: The administration of the intra-oral drugs was not capable of reducing this side effect, maybe the use of two analgesics may to present better analgesic effect to avoid the bleaching-induced tooth sensitivity (TS). Methods: A triple-blind, parallel-randomized clinical trial was conducted with 114 health patients who received either a placebo or an association of ketorolac tromethamine/acetaminophen. The first doses of two analgesic (Acetaminophen 750 mg/ Ketorolac Tromethamine 10 mg) or placebo was administered 1 h before the in-office bleaching (35% hydrogen peroxide), and extra doses were administered every 8 h for 48 h. The TS was recorded using 0-10 visual analog scale and a 0-4 numeric rating scale in different periods: during bleaching and from 1 h up to 6h, from 12 h up to 18h, from 18h up to 24 h, from 24h up to 48 h post-bleaching. The color was measured before and one month after dental bleaching with a visual shade guide Vita Classical, Vita Bleachedguide 3D-Master and spectrophotometer Vita Easyshade (Vita Zahnfabrik). The absolute risk of TS was evaluated by Fisher's exact test. Data of TS intensity with NRS scale of the two groups were compared with Mann-Whitney and Friedman tests, while data from the VAS scale were evaluated by two-way repeated measures ANOVA and Tukey's test for pairwise comparison. The color changes between groups were compared using a Student t-test (α = 0.05).

Conditions

  • Hydrogen Peroxide Allergy

Interventions

DRUG

acetam/ketoro tromet group

One hour before in-office bleaching patients received either the acetaminophen 750 mg (Paracetamol 750 mg, Bioativa compounding pharmacy) and ketorolac tromethamine oral 10 mg (Toragesic® 10 mg, EMS Sigma Farma). The operator administered the first dose of drug 1 h before the protocol, and extra doses were administered every 8 h for 48 h to keep a safe maximum daily dosage of 4000 mg of acetaminophen and 40 mg of ketorolac tromethamine.

DRUG

Placebo group

One hour before in-office bleaching patients received either placebo,The operator administered the first dose of drug 1 h before the protocol, and extra doses were administered every 8 h for 48 h.
