Introduction: The defect in the morphology of dens invaginatus causes the lack of blood supply to the pulp and consequent dental pulp necrosis, culminating in periapical lesion. Intervention with paraendodontic surgery is usual in these cases when conservative root canal treatment is unsuccessful due the complex anatomy and inaccessibility of the pulp tissue. This case reports the successful surgical root canal treatment evidenced by Cone-Beam Computed Tomography in dens in dente (type III) with considerable periapical lesion. Endodontic treatment was performed in a single session, followed by apicoectomy and retropreparation of the cavity with aid of an operating microscope and use of ultrasonic tips and retrograde obturation with Mineral Trioxide Aggregate. Lyophilized bovine bone and collagen membrane were inserted to fill the cavity. After 3-year follow-up, periapical radiographs, Cone-Beam Computed Tomography and 3D reconstruction were performed, showing favorable results as regards repair of the lesion.
