Management of the palato-radicular groove with a periodontal regenerative procedure and prosthodontic treatment: A case report

Figure 1 Tooth 12 with a complex palato-radicular groove and bone defect. A: First visit photograph showed a sinus tract on the buccal gingival surface; B: Periodontal examination revealed a deep probing depth on the distal aspect of the tooth; C: Preoperative photograph showed a groove that emerged from the cingulum; D: Preoperative cone beam computed tomography showed a palatal radiolucency close to the apex of tooth 12; E: Axial view of the middle third section of tooth 12 showed radiolucency around the distal aspect of the root; F: Dimensional reconstruction showing a large bone defect around tooth 12; G: Dimensional reconstruction showed a groove starting from the cingulum and extending to the palatal aspect of the root.

Figure 2 Multidisciplinary management of tooth 12. (A) The sinus tract disappeared after root canal treatment; (B) A teardrop-shaped defect and a deep groove; (C) Palato-radicular groove sealed with iRoot BP Plus; (D) Suturing; (E) Postoperative panoramic radiography; (F) Image after removing sutures.

Figure 3 Two-year follow-up after surgery. A: Buccal view of the clinical photograph after veneer preparation; B: Palatal view of the clinical photograph after veneer preparation; C: Postoperative cone beam computed tomography at 1 year showed the disappearance of diffuse radiolucency; D: Axial view of the middle third section of tooth 12 showed the filling of the bone defect around the distal aspect of the root; E: Dimensional reconstruction showed disappearance of the bone defect around tooth 12; F: Dimensional reconstruction showed that the groove was sealed; G: Periapical radiograph at the 2-year recall.
