Abstract:
Objective:To study the effect of calcium sodium phosphosilicate(CSP)on the enamel remineralization of primary teeth. Methods:30 extracted human healthy primary molars were collected.Each tooth was cut bucco-lingually and mesial-distally into 4 sections.The sections were assigned randomly into 4 groups(n =30).Demineralization and remineralization cyclic model was estab-lished by etching with 35% phosphate acid for 2 min and then treated by unexposure of the sample to nothing(control,group A),so-dium monofluorophosphat(MFP,group B),CSP(group C)and MFP +CSP(group D).The cyclic was repeated twice daily for 30 d. The enamel surface morphology was observed by SEM and the surface microhardness(SMH)was measured.Results:On the tenth day,squamous morphology was observed on the enamel surface of group A and that of group D appeared less demineralization.The SMH value of group D was significant higher than that of group A(P <0.05).On the thirtieth day,obvious demineralization was ob-served in group A.Group B,C and D appeared surface remineralization.The SMH value of group B,C and D was significant higher than that of group A(P <0.05).Highest SMH value was achieved in group D.Conclusion:CSP combined with fluoride is more ef-fective in the enamel remineralization of primary teeth than the single application of them.
