Objective: The aim of this study is to investigate the effect of toothpaste containing blue covarine after in-office and at-home bleaching treatments on color stability and demineralization of enamel.
Methods: Sixty patients aged between 18 and 30, with at least four anterior teeth of color A2 or above, were divided into three groups: light-activated in-office bleaching treatment with 25% HP bleach, in-office chemical bleaching treatment with 40% HP bleach, and home bleaching treatment with 16% CP content. After bleaching, each group was divided into two subgroups, using toothpaste containing blue covarine and conventional toothpaste(n = 10).Color changes were measured using a spectrophotometer initially, immediately after bleaching treatment, and at one-week and one-month follow-up periods. Demineralization levels were measured using a laser fluorescent device. Data were analyzed using repeated measures analysis of variance and multivariate analysis of variance with statistical significance.
Results At-home bleaching differed significantly from in-office bleaching treatments. Toothpaste containing blue covarine after in-office and at-home whitening treatments exhibited no significant difference from traditional toothpaste in terms of color stabilization and demineralization.
Conclusion: The use of blue covarine-containing toothpaste after in-office and at-home bleaching has similiar effect on color stabilization and demineralization as only silica-containing toothpaste.
