Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This trial evaluated the influence of polishing on enamel color change after in-office bleaching treatment. It also evaluated the influence of polishing on tooth morphology and sensitivity.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

GROUP GSEM

In-office whitening treatment with 35% Hydrogen Peroxide

Group Type OTHER

Hydrogen Peroxide 35%

Intervention Type OTHER

Group that received only bleaching treatment. Soft tissue protection was performed with a Top Dam light-curing gingival barrier (FGM, Santa Catarina, SC, Brazil). Application of whitening gel (Whitness HP 35%/FGM) on the buccal surface from premolar to premolar in the upper and lower arches. Three 45-minute sessions were held with an interval of seven days between them.

GROUP GP

In-office whitening treatment with 35% Hydrogen Peroxide + Polishing of whitened teeth

Group Type EXPERIMENTAL

Hydrogen Peroxide 35% + Polishing whitened teeth

Intervention Type OTHER

Group that received only bleaching treatment followed by polishing. Soft tissue protection was performed with a Top Dam light-curing gingival barrier (FGM, Santa Catarina, SC, Brazil). Application of whitening gel (Whitness HP 35%/FGM) on the buccal surface from premolar to premolar in the upper and lower arches. Three 45-minute sessions were held with an interval of seven days between them. After bleaching, the vestibular surfaces were polished for 20s on each bleached tooth, with polishing paste and felt disc (Diamond Flex, FGM, Santa Catarina, SC, Brazil) in low rotation.
