• Abstract:

  Dens Invanginatus, also known as dens in dens, is characterized as an anomaly that occurs during the development of tooth enamel. The best known causes are genetic or environmental factors, and 2D and 3D radiographic examinations are recommended for its diagnosis and treatment plan. With parendodontic surgery, it is possible to remove necrotic and infected remains that have lodged in the apical portion of the tooth. The aim of this study was to report a clinical case of endodontic surgery on a dens invaginatus, using a PRF graft and freeze-dried bovine bone. The use of PRF graft in this surgery is justified by its biological properties, generating deposition of growth factors, carrying out cell migration, proliferation and differentiation, its gelatinous characteristic allows better handling and adaptation of the material in the region. The external and internal anatomical complexity of the dens invaginatus makes its structure fragile. In order to make the best choice in the treatment plan, it is essential to assess the condition of the pulp and its root development. In order to better assess the healing of the periapical lesion after apicectomy, follow-up was indicated for one year after surgery using 3D technology, volumetric computed tomography.
