Summary

The aim of the present study was to evaluate colorimetric changes and tooth sensitivity in young patients submitted to tooth bleaching with 20% and 35% hydrogen peroxide.

Conditions

  • Tooth Discoloration

Interventions

OTHER

35% hydrogen peroxide

Prophylaxis was performed with a jet of sodium bicarbonate to remove extrinsic pigments and plaque. Each patient underwent two bleaching sessions. A lip retractor (Arc Flex, FGM®) was placed. Cotton roles or gauze compresses were used to achieve relative isolation. A dental dam (Top Dam, FGM®) was placed over the free marginal gingival tissue and the inter-tooth papillae of teeth 14 to 24 in each session. The Whiteness HP 35% gel was applied to the vestibular faces of these teeth. In the present study, the Whiteness HP 35% gel was applied without an external auxiliary source. As this is not a self-catalyzed system, the gel was removed after each 15-minute application and reapplied two more times, totaling 45 minutes of contact with the teeth.
