By preserving the healthy root and its supporting structures while removing the problematic root and its related coronal area, hemisection allows for the preservation of a multirooted tooth. It is a conservative treatment approach. When only one root is affected by periodontal disease, root resorption, or endodontic issues, this surgery becomes even more effective. This case study details the multidisciplinary approach taken to treat a primary endodontic lesion with secondary periodontal involvement in a first molar on the mandible. Tooth 46-related pain and pus discharge were reported by a 37-year-old female patient. During the clinical examination, we found periodontal pocketing, furcation involvement, and suppuration. On the other hand, radiographic assessment showed periapical radiolucency and distal root external root resorption. Hemisection of the distal root was executed after the initial periodontal therapy and root canal treatment. Using a bioresorbable collagen membrane produced from fish (Periocol®) and demineralised freeze-dried bone allograft (DFDBA), the remaining osseous defect was treated. Upon successful recovery, a fixed prosthesis made of porcelain fused to metal was used to reconstruct the remaining mesial root. Healing was favourable, functional stability was maintained, and periodontal support was confirmed during the 8-month follow-up through clinical and radiographic evaluation. This instance demonstrates the advantages of hemisection as a predictable, conservative, and economical method of saving strategically essential molars that could be extracted if not preserved.
