case_images: However, lateral incisors and canines have the typical talon shape appearance (Figure 1).

case_images: The left central incisor has no response to the sensibility test and shows discoloration (Figure 2). This proclination makes teeth at risk of trauma (Figures 2-4).
case_images: Case 1: proclination of upper teeth due to occlusal interference of the tubercles.

case_images: This proclination makes teeth at risk of trauma (Figures 2-4). As shown in Figures 3 and 4, tubercle interference with lower teeth leads to proclination of upper incisors and makes them at risk to trauma.
case_images: Case 1: study cast shows the large overjet of both central incisors.

case_images: Case 1: periapical radiograph shows talon cusps in all upper anterior teeth. Notice the small radiolucent teardrop in the centre of the crown of the left central incisor (dens invaginatus).

case_images: Talon cusps in both canines appear in a form of large bifid cingula (Figure 7).

case_images: The tubercles on lateral incisors are separated with shallow grooves, so are the canines (Figures 10 and 11).
