The aims of this study were to investigate the surface topography and to compare the remineralization potential of four commercial remineralizing products on deciduous and permanent teeth enamel. After artificial caries lesion formation, the enamel samples were divided into five experimental groups for permanent teeth, respectively deciduous teeth. In group 1 the samples have been stored in distilled water (control group). In group 2 each enamel sample was brushed two times a day for fourteen days with a commercial fluoride gel (Colgate® 6+ ), in group 3 each enamel sample was brushed two times a day for fourteen days with a commercial fluoride gel (CarrefourKids® +6). In group 4 a water-based cream with fluoride and hydroxyapatite (Remin Pro®, Voco) was applied for 5 minutes two times a day for fourteen days. In group 5 the enamel samples were rinsed with 20 mL antibacterial mouthwash with alcohol free natrium fluoride (Colgate® Plax) for 30 s two times a day for fourteen days. Between the remineralizing cycles, the samples have been stored in artificial saliva. The samples were analyzed using a scanning electron microscopeand an EDX detector.For primary and permanent teeth samples, lower values of calcium and phosphorus ion concentrations were recorded in groups 2-5 when compared to group 1. For groups 2 and 3 the values of calcium and phosphorus ion concentrations were nearly the same. In group 4 the concentration of both ions recorded the highest level from all study groups (groups 2-5). The lowest values of calcium and phosphorus ion concentrations were observed in group 5.All the products tested in this study had the capacity to remineralize dental enamel of primary and permanent teeth, but the remineralization was not complete. The products containing fluoride and hydroxyapatite showed a higher remineralization potential when compared to fluoride products.
