Apical periodontitis is an inflammatory disease caused by bacterial infection of the root canal system. Bacteria colonizing the root canal are usually organized in biofilms attached to the canal walls and also extending to anatomic irregularities, including lateral canals, apical ramifications, isthmuses and dentinal tubules. In these areas, bacteria may be difficult to be reached and eliminated. Organization in biofilm structures is fundamental for bacterial survival, persistence and pathogenicity. Molecular microbiology studies have identified the species/phylotypes that colonize the root canal system and are associated with apical periodontitis. Treatment strategies have been devised to control endodontic biofilms. This presentation will focus on diverse aspects of bacterial biofilms, including its formation, composition, persistence after treatment, participation in disease causation, and susceptibility to treatment.
Define the microbiological goals of the endodontic treatment.
Describe the role of bacterial biofilms in the pathogenesis of apical periodontitis.
Visualize treatment strategies to eradicate biofilms and enhance the treatment outcome for infected teeth.
