This article reports the endodontic and surgical management and 12-month follow-up of a maxillary lateral incisor diagnosed as type III dens invaginatus.A 21-year-old male patient presented to our clinics with complaints of pain and swelling in the right maxillary region. Intraoral and radiographical examination disclosed the presence of a peg-shaped maxillary right lateral incisor diagnosed as type III dens invaginatus. Root canal treatment combined with periapical surgery was initiated. After the completion of root canal treatment for both maxillary right central and lateral incisors, periapical surgery was scheduled. During the surgery, periapical granulation tissue was curreted and bovine-derived hydroxil apatite (Unilab-Surgibone, Mississauga, Ontario, Canada) covered with collagen membrane (Unilab-Surgibone) was placed in the resorptive areas. ProRoot MTA (Dentsply, Tulsa, OK) was placed as a root end filling material. Postoperative 12-month follow-up revaled a satisfactory healing process.
