Criteria
Inclusion Criteria:

- Patients aged 18 years and older, of both sexes, who had to present at least six upper
anterior teeth free of caries and restorations on the vestibular face, and 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 (Vita Classical®, Vita-Zahnfabrik-
Germany).

Prior to the interventions, the signing of each participant's free and informed consent
form (Appendix I) was obtained after due explanations about the nature of the study and the
possible risks of the proposed treatments.

Exclusion Criteria:

- The individuals excluded from the study were: users of fixed orthodontic appliances,
patients with periodontal disease, pregnant or lactating, with severe intrinsic stains
on the teeth (spots on the use of tetracycline, fluorosis and depolluted teeth),
consuming any Anti-inflammatory and anti-oxidant drugs, using desensitizing dentifrice
and participants with previous history of SD or any associated pathology (bruxism,
gingival recession, non-carious lesion with dentin exposure).
