15 Years to No maximum
Inclusion criteria
Inclusion criteria: Age over 15 years; good general and oral health; absence of caries; absence of restorations; absence of endodontic treatment on anterosuperior teeth; upper right and left canine with color A2 or lower according to the value oriented Vita Classical color scale.
Exclusion criteria
Exclusion criteria: Patients who have already had teeth whitening, who are undergoing orthodontic treatment, who have severe discoloration due to tetracycline and fluorosis stains will not be included in the study. In addition, participants with any other pathology that may cause sensitivity (such as recession, dentin exposure or the presence of visible cracks in the teeth), patients with a history of dental hypersensitivity, patients with bruxism, pregnant women, nursing mothers, smokers and patients who are using analgesic or anti-inflammatory drugs that can influence the perception of dental sensitivity.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the degree of tooth color change with the application of a modified at-home bleaching protocol with 7.5% hydrogen peroxide, applying the bleaching agent through the buccal and palatal surfaces simultaneously, through the subjective method (vita Classical scale and vita Bleachedguide scale ) and objective method (spectrophotometer vita Easyshade). | — |
Secondary
| Measure | Time frame |
|---|---|
| Assess whether the bleaching efficacy in a modified at-home bleaching protocol with 7.5% hydrogen peroxide is superior to the conventional protocol, using a visual analog scale. ;Assess the intensity of tooth sensitivity resulting from a modified at-home bleaching protocol with 7.5% hydrogen peroxide, using a visual analogue scale.;Assess the risk of gingival irritation resulting from a modified at-home bleaching protocol with 7.5% hydrogen peroxide, using a visual analogue scale.;Assess the intensity of gingival irritation resulting from a modified at-home bleaching protocol with 7.5% hydrogen peroxide, using a visual analogue scale.;Assess the risk of dental sensitivity resulting from a modified at-home bleaching protocol with 7.5% hydrogen peroxide, using a visual analog scale. ;Assessment of satisfaction resulting from a modified at-home bleaching protocol with 7.5% hydrogen peroxide using an orofacial aesthetic scale and likert scale. | — |
