Abstract：AIM:To investigate the effect of green tea extracts epigallocatechin gallate (EGCG) on the growth of Streptococcus mutans and lactobacillus.And to investigate the efficacy of EGCG solution on remineralization of etched enamel surface.METHODS:The antibacterial experiment was carried out by Oxford cup method,examination of the minimal inhibitory concentration (MIC) of EGCG against Streptococcus pneumoniae and lactobacillus.EGCG with MIC was ued for the remineralization of enamel surface etched by pH circulation method.The same concentration of NaF solution was used as positive control,distilled water as blank control.RESULTS:The MIC of EGCG on streptococcus mutans and lactobacilli was 0.25 mg/mL.And the remineralization ability of mixed solution of EGCG of MIC on etched enamel was obvious.CONCLUSION:EGCG can restrain cariogenic bacteria and promote enamel remineralization.
