DA COSTA, Eliana Dantas et al. Ankylosis of Permanent First Molar: Diagnosis by Cone Beam Computed Tomography. Int. J. Odontostomat. [online]. 2017, vol.11, n.3, pp.319-325. ISSN 0718-381X.

Ankylosis is an anomaly of tooth eruption characterized by the fusion of cementum and alveolar bone, and may affect from small regions to the entire root surface. Clinical assessment combined with imaging exams can aid diagnosis. Radiographic testing enables assessing only proximal regions of possibly affected roots. Whereas cone beam computed tomography (CBCT) allows a three-dimensional assessment of axial, coronal, and sagittal planes of all dental extension, eliminating thus overlapping images and helping to confirm the correct diagnosis. The present study contains a case report of a male patient with ankylosis in tooth 16 diagnosed by CBCT, aiming at providing information for dentists about this anomaly, its characteristics and situations in which CBCT should be indicated.

Keywords : dental ankylosis; diagnosis; cone beam computed tomography.
