Summary
Periodontal disease involves oral microbiome shifts, not just one pathogen. Restoring microbial balance and host inflammation control are key for effective treatment and preventing progression.
Area of Science:
- Oral microbiology
- Periodontology
- Inflammatory diseases
Background:
- Periodontal disease is an inflammatory condition characterized by the destruction of tooth-supporting tissues.
- It involves a shift from a symbiotic to a dysbiotic oral microbial community, rather than a single causative pathogen.
Purpose of the Study:
- To review and synthesize evidence on how oral microbiome alterations contribute to periodontal disease severity and progression.
- To explore the relationship between microbial composition, structure, functional activity, and clinical outcomes in periodontal disease.
Main Methods:
- A comprehensive literature search was conducted across PubMed, Web of Science, Google Scholar, and Embase.
- Included studies were peer-reviewed, human-based, and published between 2000 and 2026.
- Twenty-two articles were analyzed for associations between microbial patterns and clinical periodontal outcomes.
Main Results:
- Periodontal disease severity correlated with oral microbiome compositional shifts, not overall diversity or bacterial load.
- Increased prevalence of red-complex bacteria (e.g., Porphyromonas gingivalis) was linked to worsening clinical parameters.
- Aggregatibacter actinomycetemcomitans showed a stronger association with aggressive periodontal disease phenotypes.
Conclusions:
- Periodontal disease management should focus on restoring microbial homeostasis and regulating host inflammation, not solely targeting individual pathogens.
- Functional dysbiosis, indicated by enriched inflammatory and metabolic pathways, contributes to tissue destruction.
- Interventions modifying the oral ecosystem and host-microbe interactions improve microbial profiles and clinical outcomes, enabling personalized treatment strategies.

The Oral Microbiota
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Introduction to the Human Microbiota
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity, and disease...
Microbiota of the Respiratory Tract
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
Biofilms
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...
