Radicular cysts are inflammatory jaw cysts that form in the apices of infected and necrotic pulp teeth. They are usually asymptomatic and tend to grow slowly. However, depending on the progressive size of the lesion and its relation to neighboring tissues, it may cause mobility, root resorption and displacement. In addition, a limited number of studies have been reported in which paresthesia occurs as a result of local pressure caused by periapical pathology and various mandibular intraosseous lesions on nerve tissue. In this study, treatment process of the paresthesia of inferior alveolar nerve caused by radicular cyst which is remained asymptomatic for a long time in the left posterior mandible is presented in a 33 year-old male patient and it is evaluated in the light of current literature.
