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<0.001). The mean values of SL of each group were: G1 PT 18.18(±3.98), dt 25.65(±9.21); G2 PT 14.76(±2.82), dt 18.11(±3.92); G3 PT 12.62(±5.29), dt 15.61(±6.70); G4 PT 17.12(±2.24), dt 23.41(±7.9); G5 PT 13.24(±1.29), dt 18.28(±8.96) CONCLUSIONS: In permanent teeth G3 showed the best preventive effect. In deciduous teeth G1, G3 and G5 showed similar effect. This article is protected by copyright. All rights reserved.
