It has two isoforms (Mfn1 and 2) and is critical in intracellular energy production, calcium transfer, and phospholipid metabolism. Based on previous evidence linking mitochondrial function with the pathophysiology of periodontal inflammation, we hypothesized that salivary Mfn1 and Mfn2 levels may differ across periodontal health, gingivitis, and periodontitis, and that these levels correlate with markers of inflammatory and oxidative stress. Although previous studies have suggested that Mfn2 plays a role in inflammatory and oxidative pathways, clinical evidence regarding its role in periodontal disease is lacking.
