Bottom Line: The periapical radiography did not provide enough information for the differential diagnosis due to the inherent limitations of this technique.CBCT confirmed the presence of tooth fusion.Conclusion.

ABSTRACT
Objective. The objective of this paper is to report a dental fusion case focusing on clinical and radiographic features for the diagnosis. Method. To report a case of right maxillary lateral incisor fusion and a supernumerary tooth, the anatomy of the root canal and dental united portion were assessed by cone beam computed tomography (CBCT). Results. The clinical examination showed dental juxtaposition with the absence of interdental papilla and esthetic impairment in the right maxillary lateral incisor region. The periapical radiography did not provide enough information for the differential diagnosis due to the inherent limitations of this technique. CBCT confirmed the presence of tooth fusion. Conclusion. CBCT examination supports the diagnosis and provides both the identification of changes in tooth development and the visualization of their extent and limits.

(a) Cross section of the cone beam computed tomography (CBCT) reveals the union of the right maxillary lateral incisor and the supernumerary tooth at the dentin level and shows the extent and limits of the anomaly, suggesting dental fusion. Axial sections of the CBCT show signs of fusion in the (b) cervical third, (c) middle third, and (d) apical third of the root.

Axial sections of the CBCT show signs of fusion in the (b) cervical third, (c) middle third, and (d) apical third of the root.

Mentions: Considering that the diagnosis obtained by 2D image was inconclusive and that the evaluation of the extent of the dental development anomaly was clinically impossible, a CBCT investigation was requested. The 3D exam revealed the union of the teeth at the dentin level, suggesting the differential diagnosis of dental fusion of the right maxillary lateral incisor with a supernumerary tooth (Figures 3(a), 3(b), 3(c), and 3(d)).
