Question 92 · LDEK · Crowding and dental anomalies
A patient aged 10 comes to the dental office - the parents express their concern about the shape of incisors in the maxilla. The examination of the maxillary anterior part revealed that the upper central incisor has an excessively wide crown with a vertical groove on the buccal surface with a depression on the incisal margin. The tooth 12 is absent, which was confirmed radiologically. Based on these findings one may diagnose:
- A. persistent deciduous tooth.
- B. mesiodens.
- C. retained teeth.
- D. microdontia.
- E. tooth fusion.
Hint
A wide grooved crown plus a missing neighbouring tooth: did two germs merge, or did one germ split?
