Abstract: The differential diagnosis of unilocular radiolucent lesions is commonly benign; definitive diagnosis through biopsy, however, is imperative to rule out malignancy. Of the odontogenic cysts, dentigerous cyst is the most common and often associated with mandibular third molars. When a suspected dentigerous cyst is large in nature, the definitive diagnosis may be an odontogenic keratocyst or unicystic ameloblastoma. Radiographic evaluation is not sufficient to definitively discern between the three lesions. Reaching a definitive diagnosis is necessary due to increased pathogenesis associated with lesions on the differential diagnosis. This case report describes the clinical presentation of a 13-year-old female patient who presented to an outpatient pediatric dentistry clinic for a routine dental visit; panoramic revealed an incidental finding of a unilocular radiolucent lesion associated with impacted #32.
