Effects of diode laser therapy and stannous fluoride on dentin resistance under...
Passos, Vanara Florêncio; Melo, Mary Anne S.; Silva, Francisco F.C.; Rodrigues, Lidiany Karla A.; Santiago, Sérgio L.Objective: This in vitro study aimed to evaluate the effect of a low intensity diode laser (k = 808 nm; 60 J/cm2) associated with stannous fluoride on the inhibition of dentin erosion by assessing percentage of superficial hardness loss (%SHL) and calcium release into the acid solution. Materials and methods: Human root dentin slabs were assigned to eight groups (n = 10), according to treatments (control, stann...
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...
