Role of cone-beam computed tomography (CBCT) in diagnosis and treatment planning of two-rooted maxillary lateral incisor with palatogingival groove. Case report

Abstract

The complex anatomy of the palatal root groove requires detailed knowledge of the internal root morphology for endodontic treatment success. This complementary tool allows a more accurate image of hard tissue structures, such as palatal grooves and/or accessory roots, in comparison to conventional periapical radiography. The treatment plan of this primary periodontal lesion with secondary endodontic involvement was as follows: periapical surgery combined with root amputation and sealing with MTA, and guided bone regeneration. <b>Key words:</b>Palatal radicular groove, palatogingival groove, maxillary lateral incisor, cone-beam computed tomography, endodontic-periodontal lesion, guided bone regeneration.
