However, lateral incisors and canines have the typical talon shape appearance (Figure 1).
Case 1: discolored necrotic left central incisor (facial aspect).

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 1: proclination of upper teeth due to occlusal interference of the tubercles.

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 1: study cast shows the large overjet of both central incisors.

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 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).

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

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