Radiographical examination revealed carious lesion extending to the cervical third of distal root [Figure 1a]. After completion of endodontic treatment that also included removal of all carious tooth structures [Figure 1b], hemisection of distal root was performed under local anesthesia. Immediate postoperative radiograph showed the well-retained mesial root and extraction socket of the distal root filled with bone graft [Figure 1c].

A fine probe was passed through the cut to ensure separation [Figure 2a]. The socket was irrigated adequately with sterile normal saline [Figure 2b]. The distal root socket and crater-like bony defect were grafted with alloplastic bone graft (hydroxyapatite and beta-tricalcium phosphate) [Figure 2c]. At 1-month recall visit, healing was found to be satisfactory, while mobility was absent [Figure 2d].

Tooth preparation of the mesial portion of the first permanent molar and second molar was performed followed by porcelain-fused-to-metal prosthesis Figure [Figure 3a and b]. Radiographs at 3 months and 9 months suggested progressive formation of bone in the extraction socket along with resolution of radiolucency around the mesial root of #46 [Figure 3c and d].
