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.

Mentions: The clinical examination revealed that all permanent teeth had erupted, except the third and second molars. In the right maxillary lateral incisor region, two dental crowns could be seen. Flossing the interproximal region of both crowns permitted us to conclude that they were not united (Figures 1(b) and 1(c)). The caregiver reported no similar cases in the family. Since a differential diagnosis could not be offered based solely on the clinical exam, the patient underwent a periapical radiographic examination. However, this type of image did not provide enough information to elucidate the case, because it is a 2D exam that presents overlapping images (Figure 2).
