The impact of psychological stress on salivary cortisol levels in periodontitis patients: a case-control study

This study highlights a potential link between stress, cortisol levels, and periodontitis, suggesting that salivary cortisol could be a valuable biomarker. Incorporating cortisol measurements into routine dental evaluations may enable personalized treatment plans, addressing both biological and psychological contributors to periodontitis. Further research is needed to explore the long-term effects of stress on cortisol levels and periodontal disease progression, as well as the role of stress management in managing periodontitis.
