Topic: Busting Biofilm: The Role of Oral Microbes and Biofilms in Periodontics

Speaker: Tabitha Acret


Dental plaque is a structurally-and functionally-organised biofilm. Plaque forms in an ordered way and has a diverse microbial composition that, in health, remains relatively stable over time (microbial homeostasis) however in dysbiosis is responsible for caries, inflammation, gingivitis, periodontal disease and peri-implant diseases.

For dental professionals to truly be preventative health heroes, it’s important to understand the role biofilm plays in health and disease and how the role of oral biofilm translates into the daily dental practice.

Learning Objectives:

  • The role of pathogens in periodontitis
  • Examine the research and what it means for you as dental professionals
