    Effect of hydrogen peroxide at 35% with and without LED lamp activation on enamel microhardness
    (Universidad Privada Norbert Wiener, 2023-12-05) Luna Oro, Fiorella Estefani; Gómez Carrión, Christian Esteban
    This experimental study aimed to compare the effect of 35% hydrogen peroxide with and without the activation of an LED lamp on enamel microhardness. The methodology of this study was experimental, using a sample of 30 teeth, which were measured with the Vickers instrument. The teeth were divided into two groups: Control group: 15 dental pieces exposed to 35% hydrogen peroxide, and the sample group: 15 dental pieces exposed to 35% hydrogen peroxide with the use of an LED lamp. The results, obtained through the parametric t-test, determined that there were minimal differences (p = 0.001) in enamel microhardness between the initial and final values of the enamel exposed to 35% hydrogen peroxide with and without LED light. Therefore, it was concluded that there are no significant differences in the loss of enamel microhardness according to the presence or absence of LED during the tooth whitening with 35% hydrogen peroxide.
