About

Ibuprofen has been recognized as anti-inflammatory and analgesic. The purpose of this study is to determine the effect of ibuprofen 400 mg on tooth sensitivity (TS) caused by in-office bleaching.

Methods: 30 health adults who received either placebo or ibuprofen. The drugs were administered 1 hour prior to the bleaching and will be prescribed 5 doses every 8 hours during 48 hours. For bleaching will be used 35% hydrogen peroxide gel. The tooth sensitivity will be recorded for up and lower arc on two scales: VAS (visual analogic scale) and 0-4. The shade evaluation will be performed before and 30 days after bleaching with visual shade guide and spectrophotometer.

Full description

Background: Ibuprofen has been recognized as anti-inflammatory and analgesic. The purpose of this study was to determine the effect of ibuprofen 400 mg on tooth sensitivity (TS) caused by in-office bleaching.

Methods: A triple-blind, parallel design, randomized clinical trial will be conducted on 30 health adults who received either placebo or ibuprofen. The drugs will be administered 1 hour prior to the bleaching and a every eight hours during 48 hours. For bleaching used 35% hydrogen peroxide gel. The TS will be recorded for up and lower arc on two scales: VAS and 0-4. The shade evaluation will be performed before and 30 days after bleaching with visual shade guide and spectrophotometer. The % of patients that reported TS at least once during treatment and the TS intensity will be evaluated by Fisher's and Mann-Whitney tests, respectively. The color changes will be evaluated by repeated measures ANOVA.
