The above-mentioned measurements were applied to a sample consists of 25 subjects before and after rinsing with green tea for 5 min (short-term study). While, S. mutans count for saliva and plaque and GBI measurements, this experimental intervention study was carried out in the El-Azhar University dental clinic.

RESULTS:
