Neurapraxia in an infected radicular cyst and its management

Radicular cysts are the most common inflammatory odontogenic cyst of jaw that emanates from the epithelial cell rests of malassez in the periodontal ligament. 60% of cases are found in maxilla, most commonly around incisors and canines with male predilection. Most of the cases remain silent until secondarily infected. Treatment modalities of Radicular cyst according to their size and severity are extraction of the associated tooth, endodontic treatment, apical surgery, enucleation and/or marsupialization. Though, radicular cyst involving inferior alveolar nerve may cause paraesthesia due the neurosensory disturbance caused by mechanical compression or stress. Here, we report a case of neurapraxia occurred in an infected radicular cyst involving roof of the inferior alveolar nerve canal.
