Abstract:
Objective: To study Duraphat fluoride varnish on the remineralization of demineralized permanent enamel by carbonated beverages. Methods: 30 permanent premolar teeth from 12 to 25 years old young people were collected from orthodontic extraction. Enamel blocks were prepared from each tooth and randomly divided into group A (Coco cola), B(deionized water), C(Coco cola + Duraphat), D(Coco cola + 2% NaF) and E(Coco cola + artificial saliva) (n = 15), the specinens were respectively treated for 7 d. The enamel surface were observed by scanning electron microscope(SEM). The Ca2 + and P3 + content(weight percentage) were detected by energy spectrum analyzer. Results: The surface of permanent enamel of group A showed a characteristic honeycomb-like appearance, that of group B were smooth. Group C showed irregular large globule deposits on the surface, group D showed some globule structures on the surface, group E showed a little deposits on the surface. Ca2 + and P3 + content of group A was lower than that of group B, in group C was higher than in group E(P< 0. 05). Ca2 + content in group D was higher than that in group E(P< 0. 05). Conclusion: Duraphat fluoride varnish can promote the remineralization of demineralized permanent enamel by carbonated beverage.
