Inflammatory cytokines play a pivotal role in bone healing and remodeling processes; however, dysregulated inflammation can lead to delayed orthopedic fracture repair and contribute to orthodontic root resorption. This review synthesizes current evidence elucidating the mechanisms by which pro-inflammatory and anti-inflammatory cytokines influence bone cell function, tissue remodeling, and immune responses in orthopedic and orthodontic contexts. Key cytokines such as tumor necrosis factor-alpha (TNF-α), interleukins (IL-1β, IL-6, IL-10), and transforming growth factor-beta (TGF-β) modulate osteoclastogenesis, osteoblast activity, and matrix turnover. Understanding inflammatory dynamics is essential for designing targeted therapies to optimize bone regeneration, minimize adverse outcomes, and enhance patient care in both disciplines.
