Abstract

An odontogenic keratocyst （OKC） limited to the alveolar bone has never been reported. Herein, we report the first two cases of OKCs located in the mandibular alveolar bone in two adults. Radiographic examination revealed a solitary, mostly well-circumscribed radiolucency between the roots of the first and second premolars in patient 1 and between the roots of the canine and first premolar in patient 2. The histological appearance of the lesions supported the diagnosis of OKC. The rarity of this lesion and its resemblance to the more common peripheral OKC and lateral periodontal cyst may cause a diagnostic dilemma during the preoperative period.
