ABSTRACT

BACKGROUND: Alternatives to fluoride as a remineralizing agent have been explored in the field of preventive dentistry to overcome the risk of dental fluorosis and explore materials that can replicate the microstructure of the hydroxyapatite crystals. AIM: The aim of this in vitro study is to compare the surface microhardness and thus the remineralizing potential of two non-fluoridated bioactive materials in artificially induced early enamel caries on primary teeth. MATERIALS AND METHODS: A total of 60 extracted primary molars were divided into three groups: Group I (Novamin; n=20), Group II (n-HAP; n=20), and Group III (control; n=20) and were subjected to a pH cycling model to replicate the intraoral environment of demineralization and remineralization. Surface microhardness measurements were taken at baseline, after demineralization, and after remineralization. RESULTS: Test of significance using ANOVA did not show any notable difference across all three groups at all three time points. Recovery rate of surface microhardness was highest for NovaMin, followed by n-HAP and control group. CONCLUSION: NovaMin and n-HAP show promise as remineralizing agents for early enamel caries in primary molars.
