What happens when you apply an antimicrobial to an oral biofilm? You may expect the bacteria to die and perhaps the biofilm to degrade. But do they? Certain oral pathogens can communicate and build resistance to the antimicrobial treatment. Other oral pathogens may go dormant to resist the effects of the antimicrobial. This session examines biofilm evolution, bacterial quorum sensing, and bacterial dormancy. What we are learning about the evolution of polymicrobial communities within oral biofilms may shape the future of sanitizing and debriding office procedures as well as home oral care. The address concludes with an examination of the implications for the design of antimicrobials for dental office and home oral care use.
