Abstract

This study aimed to evaluate the antimicrobial activity of Emdogain® (EMD) against biofilms containing the periopathogen Porphyromonas gingivalis. A brain-Heart infusion broth inoculated with S. gordonii and P. gingivalis was perfused (7-d, anaerobiosis) through a closed circuit containing two Robbins devices as to form biofilms. The latter were then treated for 2 min with various antimicrobials (Chlorhexidine (CHX) 0.2%, Povidone iodine (PVI) 5%, PVI 10%, essential oils (EO), EO ZeroTM or EMD) (n=8) and cell densities were calculated and compared. In the present in vitro model, Emdogain® was not statistically effective (p>0.05) in killing biofilm bacteria unlike the other tested molecules.
