Effect of topical iron, fluoride application on eroded enamel in vitro

To evaluate the effect of supplementation containing iron and/or fluoride on eroded enamel in vitro. Eighty enamel specimens collected in orthodontic treatments were randomly allocated into 4 groups of 20 samples each: C (control,deionized water); Fe(2+)(15 mmol/L FeSO(4)); F(-)(1.23% NaF) and Fe(2+...

Summary:To evaluate the effect of supplementation containing iron and/or fluoride on eroded enamel in vitro. Eighty enamel specimens collected in orthodontic treatments were randomly allocated into 4 groups of 20 samples each: C (control,deionized water); Fe(2+)(15 mmol/L FeSO(4)); F(-)(1.23% NaF) and Fe(2+)+ F(-)(15 mmol/L FeSO(4) and 1.23% NaF ). Before all samples submitted to 6 alternating demineralization and remineralization cycles, they were pre-treated with one of the experimental solutions for 1 minute. One complete cycle consisted of the following steps: ①demineralization in 5 mL beverage (Coca-Cola, pH=2.58) for 5 minutes under gentle agitation; ②remineralization in 5 mL artificial saliva for 1 hour at 37°C. The effect of erosion was observed by enamel surface morphology and measured by superficial micro-hardness (SMH). One-way ANOVA was performed using SPSS18.0 software package for analysis of the data. The SMH of enamel after erosion by carbonated drinks was significantly lower than the SMH before erosio
