The Preventive Effect of Remin Pro and Neutral Sodium Fluoride on Erosion of Dental Enamel: An In Vitro Study

background and aim: carbonated diet soda is the most common etiologic factor for dental erosion, and fluoride products have been proposed as an option for the prevention of that problem. this study evaluated the effect of remin pro and neutral sodium fluoride on the prevention of dental enamel erosion using profilometry. materials and methods: this study was conducted using an experimental-laboratory method on 20 extracted premolars with no corrosion, abrasion, crack or hypocalcification. for a proper evaluation, the buccal aspect of each specimen was polished using 800- to 1200- and 2500-grit silicon carbide papers. enamel was analyzed by surface profilometry. samples were randomly allocated into two groups of remin pro and neutral sodium fluoride for pretreatment. after pretreatment, the surface roughness of enamel was measured. in the third stage, the samples were exposed to cola, rinsed with deionized water, and stored in artificial saliva, and surface loss and roughness were measured. independent samples t-test and repeated measures analysis of variance (anova) were used to analyze the data. results: according to the results of this study, neutral sodium fluoride foam and remin pro reduced enamel erosion. the mean surface roughness after pretreatments with remin pro and neutral sodium fluoride foam was less than that after polishing (p=0.004) and exposure to acid (p=0.026). conclusion: neutral sodium fluoride foam and remin pro have the same effect on preventing dental erosion.
