Objective: This in vitro study aimed to analyze the mass ratio of single- and dual-species Streptococcus mutans and Aggregatibacter
actinomycetemcomitans biofilm after exposure to Curcuma xanthorrhiza ethanol extract (Xan).
Methods: A bacterial suspension in brain heart infusion medium, enriched with 0.2% sucrose, was exposed to the Xan, incubated for 18 hrs, and
analyzed using a crystal violet assay.
Results: This research concluded that the minimum inhibitory concentration of ethanol-temulawak extract against S. mutans was 5%, while the
minimum bactericidal concentration was 15%.
Conclusions: Xan prevented biofilm formation of single-species S. mutans and dual-species S. mutans and A. actinomycetemcomitans more effectively
than it did single-species A. actinomycetemcomitans.
