Development of an in vitro biofilm formation model for screening anti-periodontal disease agents.

The results of this study revealed that S. gordonii, P. gingivalis, T. forsythia, and T. denticola could be used to develop artificial biofilms. The effects of chlorhexidine gluconate on the biofilm showed that evaluating the change in the artificial biofilm caused by the component effect in the experiments was possible via exposure to chlorhexidine gluconate. This method can efficiently evaluate the component effect and has a high potential for use as an indicator. This study demonstrated that this simulation could help develop preventive measures.
