Abstract
Fatty degenerative osteonecrosis of the jaw (FDOJ) is a chronic, aseptic inflammatory condition that is characterized by molecular disruptions in bone metabolism and necrotic bone marrow within the jawbone cavities. In contrast to the overt clinical signs typically observed in osteopathies, FDOJ frequently presents with a "silent inflammation" phenotype. The electronic databases PubMed, Scopus, and Embase were searched using appropriate search terms, and the methodology was performed according to PRISMA-ScR guidelines. The elevated expression of inflammatory mediators, particularly C-C motif Chemokine Ligand-5/Regulated on Activation, Normal T Cell Expressed and Secreted (CCL5/RANTES), fibroblast growth factor-2, and interleukin-1 receptor antagonist, distinguishes FDOJ at the molecular level and links it to systemic inflammatory and autoimmune diseases. These immunohistochemical markers play a pivotal role in the pathogenesis of chronic inflammation, immune response regulation, and abnormal bone remodeling. Advanced diagnostic tools, such as conebeam computed tomography and trans-alveolar ultrasonography, facilitate the detection of pathological changes that are not easily discernible with conventional radiography. Surgical intervention remains the primary treatment modality, often complemented by therapies that target these molecular pathways to modulate chronic inflammation. This article underscores the importance of integrating molecular diagnostics, advanced imaging, and clinical data for effective FDOJ detection and management.
