Effect extract of S. spontaneum L. on bacterial plaque

Previous research to S. spontaneum L. revealed that a bleaching agent, who traditionally used for tooth discoloration, may also act to inhibit the bacterial growth. Objective: To prove that extract of S. spontaneum L. stem that has a bleaching effect on tooth discoloration may act to the bacterial plaque in vitro. Methods: From 10 subjects were determined 17 bacterial particularly of Streptococcus α , Streptococcus γ, as well as aerobe and anaerobe bacillus. S. spontaneum L. in 10%, 7.5%, 5% and 2.5% concentrations were used to test the area of inhibitions, with povidone iodine as control. Results: The Streptococcus α, Streptococcus γ, as well as aerobe and anaerobe bacillus which treating with S. spontaneum L. extract showed the area of inhibitions at all concentrations of S. spontaneum L., except concentration 2.5%. Whereas, the result of povidone-iodine 3% control, there was no obstruction to all subject bacterial plaque that were identified. Conclusion: That S. spontaneum L. extract except in concentration 2.5% have an inhibition activity against the growth of specific tooth plaque bacteria in vitro.
