Recent studies have led to the recognition that bacteria in a healthy dental biofilm are in a protective symbiotic relationship with the host. Studies have also determined that when the composition of this biofilm shifts and harmful bacteria overcome beneficial bacteria, oral biofilm becomes damaging. Hundreds of bacterial strains (those associated with periodontal diseases are predominantly Gram-negative anaerobic bacteria), along with fungi, algae and protozoa can be found in harmful plaque biofilms.
The adherence of this damaging biofilm to the tooth and tissue surfaces, along with biofilm's protective barrier (a matrix of polymers), makes it difficult to remove
The most effective treatment regimen for the control of dental plaque biofilms requires:
• engaging patients in effective biofilm control,
• disinfecting infected pockets with a rinse prior to scaling, and
• combining scaling with a targeted antibiotic rinse to prevent the spread of infection.
