Radicular cysts and treatment concepts

The maxillofacial region is affected by a greater number of cysts than any other part of the body. Periapical radiolucencies are commonly associated with non vital teeth. Radicular cysts are the most common odontogenic cystic lesions of inflammatory origin. It is a true cyst as the lesion consists of a pathologic cavity lined by epithelium and is often fluid filled. This condition is usually asymptomatic but can result in slow growth tumefaction in the affected region. Cysts can be managed surgically or non-surgically depending on the site and size of the cyst. The aim of this review is to highlight the epidemiology, pathogenesis, radiology, clinical and histopathologic features of radicular cyst and laying emphasis on the treatment options of the cyst.
