Microbial transitions from health to disease

Area of Science:

• Microbiology
• Periodontology
• Host-Microbe Interactions

Background:

• Recent advances reveal the complexity of oral microbial populations.
• Understanding microbial acquisition, interdependency, and coevolution with the host is crucial.
• Periodontal health and disease are increasingly viewed through an integrated systems perspective.

Purpose of the Study:

• To propose a systems-based view of periodontal health and disease etiology.
• To highlight the concept of microbial biofilms as a human tissue of bacteriological origin.
• To explore the resilience of both healthy and dysbiotic oral microbial communities.

Main Methods:

• Conceptual framework integrating microbe/host/clinical interactions.
• Review of current understanding of oral microbiome structure and function.
• Analysis of resilience properties in health-associated and disease-associated microbial communities.

Main Results:

• The etiology of periodontal health and disease can be modeled as a highly connected, integrated system.
• Microbial biofilms in the mouth can be considered a human tissue of bacteriological origin.
• Both healthy and dysbiotic oral microbial communities exhibit resilience to perturbations, influenced by microbiome composition and host genetics.

Conclusions:

• Understanding the resilience mechanisms of oral microbial populations is vital for preventing periodontal disease progression.
• Restoring periodontal health may involve targeting the factors that govern microbial community resilience.
• This integrated systems view offers a new perspective for future periodontal research and therapeutic strategies.
