BACKGROUND Little is known about fluoride toothpastes effect on deciduous teeth submitted to erosive tooth wear OBJECTIVES: To evaluate the preventive effect of different toothpastes on surface loss (SL) after severe erosion/abrasion model and to compare this effect between permanent (PT) and deciduous teeth (dt). DESIGN Enamel samples were randomly divided according toothpastes groups (n=17). G1: placebo; G2: NaF; G3: AmF-NaF-SnCl anti-erosion; G4: SnF ; and G5: NaF anti-erosion for children. Samples were incubated in artificial saliva (1h), submitted to erosive challenge (3min; 1% citric acid; pH3.6; at 25°C) and to toothbrush abrasion (2min slurry immersion; 50 strokes; 200g) during 30 cycles. Surface loss (μm; mean±SD) was quantified by contactless profilometry. The effects of the two covariables "tooth" and "toothpaste" were analyzed by non-parametric ANOVA, variables with significant effects were tested by Wilcoxon tests. RESULTS dt showed significantly higher surface loss than PT in all groups (p |
