Synergistic Effect of Different Types of Tea Extract in Combination with Cinnamon Extract against Streptococcus Mutans

Aim: To determine the synergistic effect of different types of tea extracts in combination with cinnamon extract against streptococcus mutans. Method: Antibacterial activity of green tea along with cinnamon was screened by agar well diffusion techniques. Background: Streptococcus mutans is a facultatively anaerobic, gram-positive coccus. It is a common habitant of human oral cavity and is one of the major contributors to the process of dental caries. They play a major role in caries by metabolising sucrose to lactic acid. This acidic environment renders the enamel vulnerable to decay. Till date, many researchers have focused only on the effect of green tea on mutans count. But the studies on other types of tea are handful. This study aims at finding the correlation between different types of tea in combination with cinnamon extract and S.mutans count. Result: The results of this study showed that both green tea and cinnamon has good antibacterial effect. They also showed synergistic activity on the organism tested.
