The lesion is swabbed from redness mucosa that contacts the fitting surface of the denture. The swabbed material is incubated in sabourauds's dextrose agar to let the Candida albicans to grow. Green tea leaf extract is diluted in different concentrations100%, 50%,25%,12,50%, 6,25%, 3,13%,1,56% and 0,78%. After 24 hours inhibition zone will be measured. Result.
