Abstract
An appliance and corresponding method for delivering antimicrobial agents to the vicinity of dental biofilm and for killing bacteria therein includes a system () for delivering polymeric capsules containing gas bubbles and an antimicrobial agent. A source of ultrasonic energy () is provided for moving the capsules toward the biofilm, the ultrasonic energy having sufficient intensity for thereafter bursting the capsules, in the vicinity of the biofilm, releasing the gas bubbles and the agent. The gas bubbles vibrate within the ultrasound field, disrupting the biofilm, so that the released agent can act effectively against the bacteria in the disrupted biofilm.
