CRESCENTE, Camila Lopes    PINTO, Cristiane Franco. Sensitivity analysis after using desensitizing before to the whitening tooth. Rev. Bras. Odontol. []. 2016, 73, 1, pp. 34-38. ISSN 1984-3747.

The objective of this study was to evaluate the use of three different dental desensitizing before application of whitening gel with calcium. They selected 32 volunteers and these randomly divided into 4 groups (n = 8): G1) Hydrogen Peroxide 35% gel containing calcium (Ca + Gel PH) ; G2) Desensibilize KF + 2% (Gel PH + Ca) ; G3) Desensibilize KF + 0.2 % (Gel PH + Ca) and G4) P + Nano (Gel PH + Ca). The materials were applied in three sessions were held and after, sensitivity measurements using the visual analogue scale of pain through tactile and evaporative actuations. There was no statistical difference (p> 0.05) in sensitivity between individuals of different groups, in any period of assessment.
