Abstract

Chronic kidney disease (CKD) is a systemic condition marked by progressive loss of renal function, often accompanied by complications beyond the kidneys. Among these, oral soft tissue inflammation remains under-recognized despite its growing clinical relevance. Individuals with CKD frequently experience gingivitis, periodontitis, oral mucosal lesions, and xerostomia, all of which may exacerbate systemic inflammation. The bidirectional relationship between renal dysfunction and oral disease is mediated through immune suppression, accumulation of uremic toxins, and microbial dysbiosis. Neutrophil impairment, altered cytokine profiles, and changes in salivary composition contribute to a compromised oral environment, allowing chronic inflammation to persist in soft tissues. The inflammatory burden from oral tissues may influence CKD progression by elevating systemic markers such as interleukin-6 and C-reactive protein. Moreover, patients with advanced CKD or those receiving dialysis often report nutritional challenges due to oral discomfort, which further complicates disease management. Periodontal pathogens and their byproducts may enter systemic circulation, potentially aggravating endothelial dysfunction and cardiovascular risks associated with renal impairment. Despite these associations, oral health is seldom integrated into CKD care protocols. Preventive strategies involving routine screening, patient education, and interdisciplinary collaboration are essential for early detection and intervention. Coordinated care models involving nephrologists and dental professionals can facilitate timely treatment and reduce systemic complications. Enhancing awareness of the oral-systemic link and prioritizing oral health within CKD management may improve long-term outcomes and quality of life for affected individuals.
