Panoramic (Figure 1) and periapical (Figure 2(a)) radiographic examination suggested the existence of a developmental dental anomaly, with the presence of more than one root canal and apical rarefaction, as well as crown-root dilaceration.
Operative imaging sequence. (a) Initial radiograph suggesting a geminated tooth; (b) final radiograph; (c) follow-up over 6 months' radiograph.

Trey, Konstanz, Germany) (Figure 2(b)). The patient returned after 30 days for evaluation.
3D reconstruction of CBCT images with 0.25 mm axial slice thickness and 0.25 mm slice interval. Images 1-8 indicate the presence of two root canals in the maxillary left lateral incisor. Images 10 and 11 show apical rarefaction with destruction of the vestibular cortical bone.

CBCT scanning was requested for a more detailed evaluation of the canal system and identification of dental structures (Figure 3) and confirmed gemination of the maxillary left lateral incisor and also revealed the presence of two root canals, one mesiobuccal and one distopalatal, and an apical hypodense lesion with destruction of the vestibular cortical bone (Figure 3, IMG 10 and 11).
