Abstract:
Objective:To observe and compare the inhibitory effect of two concentrations of fluor protectors on demineralization of human enamel in vitro.Methods:40non-carious human enamels were randomly divided into four groups with 10 samples in each group,of which 5 samples were used for experiment,5 samples were used as spare ones.0.5% fluor protector and 0.1% fluor protector were applied to the experiment groups,while 0.02% sodium fluoride and deionizer water were applied to the control groups.Then the specimens had been dematerialized for 48h,the amounts of phosphorus and calcium dissolved in the acid solution were determined by atomic absorption spectrophotometer and ultraviolet spectrophotometer respectively.Results:The experiment groups were better than the comtrast groups at preventing demineralization,and there was significant difference between experiment groups and contrast groups(P0.05);but there was significant difference between 0.02% sodium fluoride group and vavuity group (P
