Therefore, alternatives have been sought to reduce the main limitation of the dentist. The study aimed to compare the absolute risk and intensity of the sensitivity of bleaching with hydrogen peroxide to 35%, following a protocol of non-application of the gel in the cervical area. Thirty-five patients were select for this parallel, double-blind study, split-mouth randomized trial. Randomly, the Barrier Sulcus (BS) group received the light-curable resin gingival barrier to the level of the gingival sulcus, and the Cervical Barrier (CB) group the barrier was extended by about 2mm to include the entire cervical area of the teeth. The 35% hydrogen peroxide was applied three times for 15 minutes, resulting in 45 minutes of each bleaching session. There were 2 sessions with a 1-week interval. Tooth sensitivity was recorded up to 1 hour after each session, between 24 and 48 hours after and 30 days after the second session, using the Numerical Scale (NRS) and Visual Analog Scale (VAS). The color changes was evaluated before the study, in a period of 1 week, 2 weeks and 30 days after the end of the bleaching treatment, with the Vita Cl??ssica scale, Vita Bleach scale and Easyshade spectrophotometer. Color changes of bleaching and intensity of sensitivity of tooth was evaluated by the Wilcoxon-paired test. The absolute risk of tooth sensitivity was compared by the Mc Nemar???s test (?? = 0.05). Effective bleaching was observed for both groups after three weeks, without statistical difference. Not detected difference in terms of risk of tooth sensitivity and intensity of tooth sensitivity was detected between groups. Approximately, 86% of the participants experienced tooth sensitivity, which was recorded mainly as ??????mild.?????? The non-application of the gel with hydrogen peroxide to 35% does not seem to affect the degree of bleaching and tooth sensitivity. Apesar de sua comprovada efetividade, o clareamento dent??rio pode levar ?? duvida quanto a presen??a de sensibilidade dent??ria. Por isso, tem-se buscado alternativas que possam reduzir a principal limita????o do cirurgi??o-dentista. O objetivo deste trabalho foi comparar o risco absoluto e a intensidade da sensibilidade do clareamento com per??xido de hidrog??nio a 35%, seguindo um protocolo de n??o aplica????o do gel no ter??o cervical. Trinta e cinco pacientes foram selecionados para este ensaio cl??nico randomizado, paralelo, duplo cego e do tipo boca-dividida. Randomicamente, o grupo Barreira no Sulco (BS) recebeu a barreira gengival de resina fotopolimeriz??vel at?? o n??vel do sulco gengival, e o grupo Barreira Cervical (BC) a barreira foi estendida por cerca de 2mm at?? que inclu??sse toda a regi??o do ter??o cervical dos dentes. O per??xido de hidrog??nio a 35% foi aplicado tr??s vezes por 15 minutos, resultando em 45 minutos de cada sess??o de clareamento. Foram realizadas 2 sess??es com intervalo de 1 semana. A sensibilidade foi avaliada em 1 hora ap??s cada sess??o, entre 24 e 48 horas ap??s e no retorno de 30 dias, por meio da Escala Num??rica (NRS) e da Escala Visual Anal??gica (VAS). A avalia????o da cor foi realizada antes do estudo, em um per??odo de 1 semana ap??s a primeira sess??o, 2 semanas ap??s a primeira sess??o e 30 dias ap??s a segunda sess??o, com a escala Vita Cl??ssica, escala Vita Bleach e espectrofot??metro Easyshade. A mudan??a de cor do clareamento e a intensidade da sensibilidade dent??ria foram avaliadas pelo teste de Wilcoxon pareado. O risco absoluto de sensibilidade dent??ria foi comparado pelo teste Mc Nemar (?? = 0.05). A efic??cia do clareamento foi observada nos dois grupos ap??s 3 semanas do tratamento, sem diferen??a estat??stica. N??o foi detectada diferen??a nos termos de risco ?? sensibilidade e intensidade da sensibilidade entre os grupos. Aproximadamente, 86% dos participantes experimentaram sensibilidade dent??ria, que foi registrada principalmente como ???leve???. A n??o aplica????o do gel com per??xido de hidrog??nio a 35% no ter??o cervical parece n??o afetar o grau de clareamento e a sensibilidade dent??ria.
