Aging, inflammation, immunity and periodontal disease

Area of Science:

• Oral immunology
• Gerontology
• Periodontology

Background:

• Periodontal disease prevalence and severity increase with age, affecting most adults over 50.
• Aging involves immune system modifications (immunosenescence) and increased inflammation (inflammaging).
• These age-related immune changes heighten susceptibility to infections, neoplasia, and autoimmunity.

Purpose of the Study:

• To explore the role of immunosenescence and inflammaging in age-associated periodontal disease.
• To understand how altered immune and non-immune cell functions in the periodontium contribute to inflammaging.
• To highlight the need for further research into age-related periodontal changes for personalized dentistry.

Main Methods:

• Review of existing literature on aging, immunology, and periodontal disease.
• Analysis of the interplay between microbial challenges, immune responses, and aging in the periodontium.
• Focus on both adaptive and innate immune system alterations in aging.

Main Results:

• Prolonged microbial exposure in the periodontium contributes to aging effects.
• Altered cellular functions within the periodontium are hypothesized to drive inflammaging in periodontal disease.
• Both innate and adaptive immune compartments are significantly affected by aging.

Conclusions:

• Immunosenescence and inflammaging are key factors in age-related periodontal disease.
• Understanding these phenomena is crucial for developing targeted therapies in precision dentistry.
• Further investigation into age-associated periodontal changes is warranted.
