ABSTRACT
The purpose of study was to observe the effect of fluoride and calcium on enamel remineralizaton in vitro. Human premolar enamel specimens were prepared by demineralization in 0.1~1.0% citric acid for 60 minutes. They were remineralized for 6 hours in one of the 1311owing solutions : (1) artificial saliva, (2) artificial saliva with 100ppmF, (3) artificial saliva with 1000ppmF, (4) artificial saliva with 1000ppmCa, and (5) artificial saliva with 100ppmF and 1000ppmCa. No significant remineralization was occurred in artificial saliva and artificial saliva with 100ppmF. Significant remineralization was observed in artificial saliva with 1000ppmF at 3 hours, and in artificial saliva with 1000ppmCa and artificial saliva with 100ppmF and 1000ppmCa at 3 and 6 hours(P<0.05). The remineralization effect of artificial saliva with 100ppmF and 1000ppmCa was greater than that of artificial saliva or artificial saliva with 100ppmF. Addition of F to 100ppm or 1000ppm, addition of Ca to 1000ppm, and increasing the concentration of F from 100ppm to 1000ppm did not significantly increase the remineralization.
