ABSTRACT
Objective:
To observe the effect of purified high rela ti ve molecular mass mucin(MG1) pellicle on the protection of human dental enamel against demineralization.Methods:
MGI was extracted from human saliva and purified.MGI pellicle and whole saliva pellicle were formed on dental enamel samples in vitro ,Then The samples were treated by 34 mmol/L citric acid for 1 min.The demineralization of the samples was observed by scanning electronic microscopy(SEM).Results:
After treatment by the acid the enamel surfaces covered by MGI pellicles or whol e saliva pellicle showed relatively smooth and normal enamel morphological feat ures, on the contrary the surface without pellicle showed large area of deminer alization and bee nest like appearance.Conclusion:
The data indicate that the MG1 in enamel pellicle contribute to its protective effec ts against acidic attack on the enamel surface.
