Resumo
O presente estudo teve o objetivo de avaliar pH, potencial elétrico (EP) e temperatura de diferentes protocolos de clareamento dental. Foram realizados 3 estudos in vitro: o primeiro que utilizou apenas gel de concentrações diferentes (n=9, por grupo). No segundo, os grupos foram divididos em apenas gel com ou sem a presença presença de luz. No terceiro, foram utilizados 84 dentes terceiros molares permanentes (n=14, por grupo). O estudo experimental foi dividido em 12 grupos variando de acordo com presença ou não de manchamento nos espécimes dentários, concentração de peróxido de hidrogênio (HP) utilizada e presença ou não de luz violeta no protocolo. As concentrações de HP utilizadas foram de 6%, 15% e 35%. Foram avaliados pH, EP e temperatura durante o clareamento com auxílio de um pHmetro em cada grupo nos intervalos de: 1, 5, 10, 15 e 30 min. Os dados foram analisados por ANOVA de medidas repetidas com pós-teste de Bonferroni (α=0,05).
The present study aimed to evaluate pH, electric potential(EP) and temperature of different tooth whitening protocols. Three in vitro studies were performed: the first used only gels of different concentrations (n=9, per group). In the second, the groups were divided into only gel with or without the presence of flashing light. In the third, 84 permanent third molar teeth were used (n=14, per group). The experimental study was divided into 12 groups, varying according to the presence or absence of staining in the dental specimens, the concentration of hydrogen peroxide (HP) used and the presence or absence of flashing violet light in the protocol. The HP concentrations used were 6%, 15% and 35%. pH, EP and temperature were evaluated during bleaching with the aid of a pH meter in each group at intervals of: 1, 5, 10, 15 and 30 min. Data were analyzed by repeated measures ANOVA with Bonferroni post-test (α=0.05).
