Dental caries is known as a major oral health problem induced by Streptococcus . and Lactobacillus as primary contributing microorganisms responsible for this condition. The aim of this study was to compare the effect of Green tea/ Green coffee Bean Extracts and Chlorhexidine Gluconate on Streptococcus mutans count. The study was conducted among 90 preschool children aged from 4 to 6 years. Statistical analysis was done using the Shapiro-Wilk test, Friedman test, Chi-square test, paired sample t-test, repeated measures analysis of variance (ANOVA) and Mann-Whitney U test at a signi icance level of 0.05. The results demonstrated a signi icant difference in the mean of salivary S. mutans count after administration of CHG (p-value=0.001) and GT (p-value=0.02) between three different times. The study results indicate the bene icial effects of Green Tea/ Green Coffee Bean extracts and Chlorhexidine Gluconate on salivary Strepto- coccus mutans count.
