Avaliação da remineralização de esmalte dental bovino por meio da técnica de oct após aplicação de laser diodo de alta potência e fluoretos

Abstract

The association of laser use and fluoride seems to be able to accelerate the therapeutic process of early dental caries lesions in dental enamel. The aim of this study was to evaluate the attenuation coefficient of incipient caries lesion in dental enamel after diode laser irradiation and fluoride treatment using the OCT technique. The specimens were prepared for initial caries lesion formation and diode laser irradiation and topical fluoride treatment. The Carie group only caries lesion, laser, caries lesion plus 808 nm diode laser irradiation and the other groups, VF-5% caries lesion with 5% fluoride varnish, VF-5% + laser, caries lesion and laser 808nm diode and 5% fluoride varnish, FFA caries lesion plus acidulated phosphate fluoride, FFA + L caries lesion plus acidulated phosphate plus 808nm diode laser, caries lesion was induced in all samples and groups, VF -5%, VF-5% + laser, FFA and FFA + L received fluoride treatments. For surface characterization will be used the Optical Coherence Tomography (OCT), the average of the attenuation coefficient value of each sample were statistically analyzed by ANOVA. OCT detected significant differences in mineral loss between samples in relation to treatment time, the maximum remineralizing effect after 7 days can be observed in groups L-VF-5%, VF-5% + L and maximum remineralizing effect after 14 days. in the FFA and FFA-L groups. The VF-5% + L group showed significantly higher remineralization values than the other groups evaluated. It was concluded that the applied fluorides were able to decrease the attenuation coefficient in all groups, the FFA and FFA plus Diode laser presented higher remineralization in 14 days and L-VF-5%, VF-5% + L groups. Yourself with greater remineralizing effect in 7 days.
