Inclusion criteria

Inclusion criteria: Age between 18 and 40 years; Good systemic and oral health, with vital anterior teeth and premolars

Exclusion criteria

Exclusion criteria: Underwent any bleaching procedure (in-home or in-office) or any desensitizing protocol within the last 6 months; Teeth with higher value than B1 (Vita Scale; Dentin hypersensitivity history; Dentin hypersensitivity risk factors: enamel cracks or defects, dentin exposure, gingival recession, non carious cervical lesions, acid diet, gastroesophageal reflux and bruxism; Dental plaque, caries or calculus; and periodontal disease; Unsatisfactory dental restoration; Buccal dental restoration in anterior teeth; Severe staining; Using a toothpaste for sensitive teeth within the time of the research; Pregnants or lactating women; Smokers

Design outcomes

Primary

MeasureTime frame
We aim to define a prevention protocol for dental sensitivity induced by dental bleaching using the pain evaluation method Numerical Visual Scale in a 2 week following after the bleaching session. It will be possible to observe de pain occurrency and intensity and its expected to find a greater intensity and occurrency in the control group which no desensitizing method will be applied.—

Secondary

MeasureTime frame
It is expected to be found in every intervention group that the desensitizing methods will not intervene in the bleaching process, using a spectrophotometer to evaluate the initial and final color of the tooth of each patient and using statistical methods to verify this assumption.—
