Separated root tip formation associated with a fractured tubercle of dens evaginatus: A case report

Figure 1 Preoperative clinical and radiographic evaluation. A: Overview of mandibular dentition shows a gingival sinus (white arrow) on the buccal side of tooth # 45. The right column is a local enlarged image of the orange dotted area with the white circle showing the fractured tubercle of dens evaginatus on the occlusal surface of tooth # 45; B: Panoramic radiograph at the initial visit showing that the root of tooth # 45 was fractured and separated. The separated root apex was almost completely formed, and the main root remained immature with thin root walls associated with a large radiolucency (black arrow).
