Pathophysiological mechanism of the developing maxillofacial radicular cyst

The radicular cysts are result of inflammatory process in the periapical tissues associated with necrotic and infected pulps. Humoral and cellular immune responses play a central role in the pathogenesis of these lesions. The most important role in the growth of these lesion have proinflammatore cytokine TNF-?, IL-1 and IL-6. Cytokine can be secreted by macrophages, monocytes and other cells of the immune system and can participate in skeletal homeostasis including osteoclastic formation, and bone resorption in maxillofacial region. The aim of this study is to give a concise review for mechanism of growth of maxilofacial radicular cysts, indicated of clinical aspect, as well as explained role of cytokine in this pathophysiology process.
