Assessing of Tooth Sensitivity Using Ibuprofen Before in Office-tooth Bleaching
Assessing of Tooth Sensitivity Using Ibuprofen Before in Office-tooth Bleaching: a Randomized, Triple-blind Clinical Trial
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.
Study Overview
Detailed 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.

- pregnant/lactating.
- with severe internal tooth discoloration (tetracycline stains, fluorosis, pulpless teeth).
- taking any kind of medicine, bruxism habits or any other pathology that could cause sensitivity (such as recession, dentine exposure).

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Tooth sensitivity evaluation
Time Frame: Sensitivity during the treatment and until 48 hours after bleaching. The tooth sensitivity will be evaluated only this period because the literature appoint dates in this time.
|
Patients will be distributed in two groups: Group 1 - Control Group will receive placebo.
Group 2 - Ibuprofen will receive not selective anti-inflammatory (Ibuprofen 400 mg).
All of the drugs will be administered one hour before the bleaching treatment.
Evaluation of Dental Sensitivity Level: the effect of the product will be evaluated up to 1 Hour, 24 and 48 hours after the tooth bleaching, using a verbal scale of 5 points and a Visual Analogue Scale (VAS) will be used.
|
Sensitivity during the treatment and until 48 hours after bleaching. The tooth sensitivity will be evaluated only this period because the literature appoint dates in this time.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Shade evaluation
Time Frame: Shade evaluation was recorded before and 30 days after the bleaching treatment.
|
Shade evaluation was recorded using two methods: the subjective evaluation using a shade guide (Vita Lumin, Vita Zahnfabrik, Bad Säckingen, Germany) and an objective evaluation using the spectrophotometer (Easyshade, Vident, Brea, CA, USA).
|
Shade evaluation was recorded before and 30 days after the bleaching treatment.
