Inclusion criteria: Have a voluntary interest in undergoing aesthetic treatment for teeth whitening; be between 18 and 30 years old, regardless of gender; presenting from the first to the first molar, in the upper and lower arches, healthy, without lesion of caries and / or restoration on either side; present the teeth with initial color B2 or darker, according to the Vita Classic scale (Vita Lumin, Vita Zahnfabrik, Bad Sackingen, Germany); present oral health (absence of lesion or any type of suggestive alteration of pathology); good oral hygiene and periodontal health.
Exclusion criteria
Exclusion criteria: People who have already had dental bleaching; self-reported dental sensitivities (spontaneous and / or provoked, have healthy teeth with severe color changes that can not be corrected with dental bleaching, are under medical treatment or use controlled medication, have any type of systemic alteration; history of sensitivity to hydrogen peroxide, present recessions of the gingival tissue and exposure of the dentinal tissue in the cervical region, present parafunctional habits and painful symptomatology of the temporomandibular joint (TMJ), being smoker, presenting any type of pathological alteration in the oral cavity; use of orthodontic appliance or dental prosthesis, if female, be pregnant or breastfeeding.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1: Evaluate a protocol of LED irradiation in relation to the dental sensitivity, measure by the pain scale, after clarifying with the hydrogen level to 35%, consists in the observation of a variation of at least 5% in the pre and post-intervention evaluations. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome 2: To assess the intensity of pain sensitivity experienced in the evaluation times through two pain scales, visual analogue scale and 5-point scale, after bleaching with hydrogen peroxide at 35%, from the observation of a variation of at least 5% in the pre and post intervention measurements.;Expected outcome 3: To quantify the number of teeth affected by pain sensitivity, through counting, after bleaching with hydrogen peroxide at 35%, from the observation of a variation of at least 5% in the pre- and post-intervention measurements. | — |
