The antibacterial effects of coffee extract, chlorhexidine, and fluoride against Streptococcus mutans and Lactobacillus plantarum: An in vitro study

Conclusion: The coffee had an antibacterial effect against S. mutans on 62.5 –1000 mg/mlconcentrations. The zone of inhibition around S. mutans for higher concentrations of coffee(6.25% –100%) was significantly higher than that of CHX and fluoride 0.2%. Bacteriostatic effect ofcoffee against L. plantarum was obtained at 500 –1000 mg/ml. However, coffee and fluoride did notshow any bactericidal effects against L. plantarum.Key Words: Chlorhexidine, coffee, sodium fluoride, Streptococcus mutans
