Evaluating the potential remineralization effect of NovaMin prophylaxis paste on artificial enamel lesions in primary teeth using Vickers microhardness and scanning electron microscope.
 Forty sound buccal and lingual surfaces of human primary canine teeth were randomly divided into two groups after creating artificially demineralized lesions (G1: NovaMin and G2: fluoride; 20 per group) and then treated with the respective remineralization agents. The remineralization cycle repeated twice daily for 10 days. The groups were evaluated with Vickers microhardness and scanning electron microscope before and after de/remineralization.
 Statistically significant difference of microhardness was observed between demineralized enamel and remineralized enamel with group 1 and group 2 ( = 0.000 and = 0.000, respectively). No statistically significant difference of microhardness was observed between two remineralized agents ( = 0.368).
 Within the limitation of this study, NovaMin enhances the remineralization process equally to fluoride.
