Occlusal radiograph revealed buccal cortical plate expansion extending from distal aspect of permanent mandibular left lateral incisor to mesial aspect of permanent mandibular left second molar and revealed an interesting finding that the successive premolar was displaced and aligned buccolingually in the cystic cavity (Fig. 3).
