Eligibility
Age
18 Years to 60 Years
Inclusion criteria
Inclusion criteria: This trial will include adults between 18 and 30 years old, regardless of gender, with good dental and periodontal health. Specifically attention will be given to six maxillary anterior teeth, which will be required to be caries-free and without buccal restorations. Shade of central incisors will be required to be A2 or darker in a value-oriented shade guide (VITA EasyShade Advance, Vita Zanhnfabrik).
Exclusion criteria
Exclusion criteria: This trial will exclude participants who have previously undergone tooth-bleaching procedures, dental sensitivity, pregnancy or lactation, and severe tooth pigmentation caused by drugs, fluorosis, or pulpal pathology. Participants will also be excluded if they are taking any form of medication (especially anti-inflammatory drugs), bruxism, enamel cracks, gingival recession, class V cavities, dentin exposure, or any other clinical condition that could cause dental sensitivity.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the absolute risk of tooth sensitivity when using a dentifrice containing 5% potassium nitrate compared to a dentifrice without this active ingredient, related to an in-office tooth bleaching with 35% hydrogen peroxide. | — |
Secondary
| Measure | Time frame |
|---|---|
| Evaluate the effect of using a 5% potassium nitrate dentifrice in the whitening efficiency of 35% hydrogen peroxide by using a subjective method, such as the Vita Classical shade guide (Vita Lumin, Vita Zahnfabrik, Bad Säckingen, Germany), and an objective method, such as the spectrophotometer Vita Easy Shade (Vita Zahnfabrik, Bad Säckingen, Germany). | — |
