Fluoride releasing and enamel demineralization around orthodontic brackets by f...
Melo, Mary A. S.; Morais, Weslanny A.; Passos, Vanara Florêncio; Lima, Juliana P. M.; Rodrigues, Lidiany K. A.Introduction Fluoride-containing materials have been suggested to control enamel demineralization around orthodontic brackets during the treatment with fixed appliances. The improvement of their properties has been made through innovations, such as the application of nanotechnology by incorporation of nanofillers. Objective This in vitro study evaluated the capacity of fluoride releasing and enamel demineraliza...
Comparison of methods for quantifying dental wear caused by erosion and abrasion
Passos, Vanara Florêncio; Melo, Mary A. S.; Vasconcelos, Andréa Araújo; Rodrigues, Lidiany K.A.; Santiago, Sérgio L.Various methods have been applied to evaluate the effect of erosion and abrasion. So, the aim of this study was to check the applicability of stylus profilometry (SP), surface hardness (SH) and focus-variation 3D microscopy (FVM) to the analysis of human enamel and dentin subjected to erosion/abrasion. The samples were randomly allocated into four groups (n 5 10): G1-enamel/erosion, G2-enamel/erosion plus abras...
Dentin erosion by whitening mouthwash associated to toothbrushing abrasion : a ...
Lima, Juliana P.M.; Melo, Mary A. S.; Passos, Vanara Florêncio; Braga, Cícero L. N.; Rodrigues, Lidiany K. A.; Santiago, Sérgio L.The aim of this study was to determine the erosive potential of hydrogen peroxide (HP) containing mouthwash on dentin assessed by Focus variation three-dimensional (3D) microscopy. Twenty dentin slabs were selected and randomly allocated into two groups (n 5 10): DW—Distilled water (pH 5 7.27) and HP—1.5% (pH 5 3.78). Each specimen was cyclically demineralized (4 3 60 s/day, 10 days) with HP or DWand brushed 33...
