[Stress and periodontitis]

Area of Science:

• Oral health
• Immunology
• Microbiome research

Background:

• Reduced immune fitness disrupts the host-microbiome balance, exacerbating gingivitis and periodontitis.
• Lifestyle factors such as stress and smoking significantly impair immune fitness.
• Stress is linked to periodontitis and acute necrotizing ulcerative gingivitis, potentially via neuronal pro-inflammatory mediators.

Purpose of the Study:

• To explore the impact of stress on immune fitness and its role in the pathogenesis and treatment of periodontal diseases.
• To investigate the potential mechanisms by which stress influences the oral microbiome and inflammatory responses in the periodontium.

Main Methods:

• Review of existing literature on stress, immune function, and periodontal disease.
• Analysis of in vitro studies examining the effects of cortisol on oral bacteria like P. gingivalis.
• Clinical observations and associations between stress, periodontal status, and treatment outcomes.

Main Results:

• Stress and smoking are identified as key lifestyle factors that reduce immune fitness and negatively affect periodontal health.
• Evidence suggests neurons may secrete inflammatory cytokines, worsening chronic periodontitis and compromising immune defenses.
• In vitro data indicate elevated cortisol levels can promote the growth of P. gingivalis, a key pathogen in periodontitis.

Conclusions:

• Stress is a significant, though clinically challenging to quantify, risk factor for periodontitis.
• Awareness and management of stress are vital components of comprehensive periodontal care to mitigate its detrimental effects on immune fitness and treatment success.
