Dentin Sensitivity
Conditions
Interventions
Control group: In group 1 (G1-control, 28 patients), the operator applied a desensitizing gel based on 5% potassium nitrate and 2% sodium fluoride with the aid of a custom silicone tray, which was mad

Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: patients aged 18 years and older; of both sexes; at least six upper anterior teeth free of caries and restorations on the vestibular face; at least one central or canine incisor showing coloration A2 or darker, evaluated in comparison to a visual value-oriented color scale of the teeth.
Exclusion criteria
Exclusion criteria: users of fixed orthodontic appliances; patients with periodontal disease; pregnant or lactating women; severe intrinsic stains on the teeth (spots on the use of tetracycline, fluorosis and depolluted teeth); consuming any Anti-inflammatory and antioxidant drugs; using desensitizing dentifrice and participants with previous history of SD or any associated pathology (bruxism, gingival recession; non-carious lesion with dentin exposure).
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| expected outcome 1: decrease of absolute risk of dental sensitivity for office bleaching using 40% hydrogen peroxide was evaluated through two scales for pain assessment: the Verbal Evaluation Scale and the Visual Analogue Scale, from a variation of at least 37% in measurements between the control and experimental groups. The evaluations were realized from January to April 2017. ;found outcome 1: no significant difference was observed in the intensity of dental sensitivity in the comparison between the group (p = 0.37), evaluated through two scales for pain assessment: the Verbal Evaluation Scale and the Visual Analogue Scale, from a variation of at least 37% in measurements between the control and experimental groups. | — |

| Measure | Time frame |
|---|---|
| expected outcome 2: increase of effectiveness of tooth bleaching was analyzed using the spectrophotometer and two color scales (Vita Classical and Bleachedguide) before bleaching and after 7, 14 and 28 days, from a variation of at least 5% in measurements between the control and experimental groups.;found outcome 2: an increase in the effectiveness of bleaching was observed for both groups (9-10 shade guide units) using the spectrophotometer and two color scales (Vita Classical and Bleachedguide) before bleaching and after 7, 14 and 28 days, from a variation of at least 5% in measurements between the control and experimental groups. No statistically significant difference was observed between the study groups (p > 0.12).;expected outcome 3: decrease of intensity of dental sensitivity was analised through two scales for pain assessment: Verbal Evaluation Scale and Visual Analogue Scale, during bleaching and up to 48 hours after, from a variation of at least 5% in measurements between the control and experimental groups.;observed outcome 3: no significant difference was observed in the intensity of dental sensitivity in the comparison between the groups (p = 0.38) through two scales for assessment of pain: the Verbal Evaluation Scale (VRS) and the Visual Analogue Scale (VAS), during bleaching and up to 48 hours after, from a variation of at least 5% in measurements between the control and experimental groups. | — |
