Area of Science:

  • Periodontal microbiology and microbiome research.
  • Systems biology and ecological principles applied to host-associated microbes.

Background:

  • Historically, periodontal microbiology focused on identifying disease-causing microbes, limiting understanding of the ecosystem's diversity and health contributions.
  • The subgingival niche harbors a complex microbial community essential for maintaining homeostasis.
  • Microbiomics offers a new lens to study these communities in their natural environment.

Purpose of the Study:

  • To revolutionize the understanding of host-associated microbes and the human microbiome.
  • To explore the complex relationships within the periodontal microbiota and between microbes and the human host.
  • To investigate how advanced 'omics' technologies have reshaped periodontal science.

Main Methods:

  • Utilizing microbiomics (metagenomics, genomics, metatranscriptomics, proteomics, metaproteomics, metabolomics) to characterize microbial communities.
  • Applying systems biology and ecological principles to analyze microbial interactions.
  • Examining the influence of host-associated factors and external influences on the microbiome.

Main Results:

  • Broadened the view of the periodontal microbiome beyond just bacteria.
  • Expanded understanding of the human oral microbiome's evolution.
  • Elucidated the impact of human behavior and systemic diseases on microbial communities.
  • Revealed the effects on traditional periodontal therapeutic approaches.

Conclusions:

  • The shift to a microbiome-centric approach provides a more holistic understanding of periodontal health and disease.
  • Advanced 'omics' technologies are crucial for deciphering complex microbial ecosystems.
  • Future periodontal therapeutics may be influenced by microbiome-based insights.
