Impact of systemic diseases on periodontal remodeling: Mechanisms, mediators, and clinical relevance

Abstract Background Periodontal remodeling is a continuous, adaptive process essential for maintaining the structural and functional integrity of periodontal tissues. While external factors such as bacterial biofilm, excessive forces, and poor oral hygiene are recognized triggers of periodontal pathologies, they do not fully explain their persistent prevalence. Objective This opinion paper emphasizes the impact of systemic diseases on periodontal homeostasis and considers periodontal disease as a manifestation of systemic dysfunction rather than solely a bacterial local disease. Methods This paper is conceptually designed as a narrative review and synthesizes the molecular and cellular mechanisms through which systemic diseases converge to disrupt periodontal remodeling. Results Emerging evidence underscores the critical role of systemic diseases, including chronic kidney disease, cardiovascular disease, liver dysfunction, and hematologic malignancies, in addition to studied uncontrolled diabetes mellitus, in destabilizing periodontal homeostasis. These systemic conditions are all associated with excess systemic inflammation that impairs regenerative capacity, mineralization, vascularity, and immune responses, fostering a subclinical environment prone to periodontal tissue pathologies with clinical impact. This opinion paper is conceptually designed as a narrative review and synthesizes the molecular and cellular mechanisms through which systemic diseases converge to disrupt periodontal remodeling, including periodontal pathologies as a consequence of systemic dysfunction rather than a purely bacterially induced local disease. Conclusion Clinically, this understanding demands intensified dental surveillance to uncover modifiers of susceptibility and interdisciplinary care for systemically compromised patients. Future research should identify early biomarkers of systemic impact and inform strategies that integrate oral and systemic health to reduce the periodontal disease burden.
