Abstract
AIM: The aim of this study was to investigate the effects of toothpastes with different contents on the remineralization of white spot lesions around orthodontic brackets by quantitative light-induced fluorescence (QLF). MATERIALS AND METHODS:A total of 45 freshly extracted human mandibular first molars were selected. Artificial caries lesions were created on enamel surfaces using an acidified gel system for 7 days. Initial relative fluorescence loss was calculated as the pretreatment (baseline) fluorescence value by QLF device. Molar tubes were bonded using light-cured resin composite cement. The specimens were randomly divided into three experimental groups (n = 15). Different toothpastes were applied to demineralized enamel: (1) fluoride-containing toothpaste (Colgate Total®), (2) Novamin-containing toothpaste (Sensodyne® Repair and Protect), (3) probiotic-containing toothpaste (GD Probiotic Toothpaste®). After 2 weeks of treatment, fluorescence loss and lesion area were measured with QLF. To determine fluorescence changes, intergroup comparisons were performed with a multivariate analysis of variance, followed by Tukey's test at a probability value of p < 0.05. RESULTS: Significant differences were observed between initial and posttreatment QLF measurements of the demineralized enamel specimens treated with the various agents (p < 0.05). In all experimental groups, significant fluorescence radiance increase and decrease of the lesion area (p = 0.000) was found. CONCLUSION:Novamin-containing toothpaste provided more increase of fluorescence compared to fluoride- and probiotic-containing toothpastes.
