Analysis of two remineralizing agents in incident caries injuries through afm

Abstract

Dental caries if treated early in their primary stages can be stopped and limited with preventive therapies that favor remineralization. Objective: To evaluate the remineralization of incipient caries lesions (white spot) from the application of two remineralizing agents. Materials and methods: An in-vitro study was carried out with samples of dental enamel divided into 2 groups, Group A (n = 15) and Group B (n = 15), demineralization was generated with a solution of lactic acid and artificial saliva, For remineralization, Group A was applied the bioactive glass Calcium fluorinated sodium phosphosilicate (BAGF), Group B was applied the Casein Phosphopeptide - fluorinated amorphous calcium phosphate (CPP-ACPF), this procedure was performed by 10 days, Results: In Group A, values of 1,967 nm, 33,128 nm and 5,964 nm respectively were obtained, in Group B the values were 2,296 nm, 34,335 nm and 13,611 nm, using the Student's t-test, a p -value = 0.108> 0.05 for healthy enamel and a p-value = 0.193> 0.05 for demineralized enamel, indicating that there was no significant statistical difference between the values of healthy and demineralized enamel of the two groups; however, for remineralized enamel, it indicated a large difference between the remineralization values of both groups. Conclusion: The fluorinated sodium and calcium phosphosilicate remineralizing agents (BAGF) and fluorinated amorphous calcium casein phosphate (CPP - ACPF) remineralize demineralized dental enamel, bioactive glass (BAGF) being more effective.
