1. Supernumerary tooth (SN2) at roots 24 and 25
A supernumerary tooth (labeled SN2 in the adjacent images) is developing palatally to the roots of teeth 24 and 25. This tooth has not had any effect on teeth 24 and 25. The crown of the tooth is positioned adjacent to the lingual cortex of the maxillary alveolar process. Root formation is approximately 20% complete on this tooth.
Supernumerary tooth (SN1) palatal to roots 23 and 24
A supernumerary tooth is developing lingually to the roots of teeth 23 and 24. This tooth has not caused any damage to the roots of teeth 23 and 24. The crown of the tooth is positioned against the palatal surface of the maxillary alveolar process, and the root is approximately 70% formed.
Supernumerary tooth palatal to teeth 12 and 13
A supernumerary tooth is positioned palatally to the roots of teeth 12 and 13 at the midroot level. The cusp tip of the supernumerary tooth is positioned at the lingual surface of the maxillary alveolar process adjacent to tooth 13, and the root is positioned palatally to the apical third of the root of tooth 12. No damage or resorption is present on teeth 12 and 13.
Axial slices of maxilla
These axial cross sectional images demonstrate the palatal positions of the three supernumerary teeth in the anterior maxilla.
2. Small odontomes developing between the roots of 33 and 34
Three small odontomes are forming within one large follicle between the roots of teeth 33 and 34. These odontomes are most clearly seen in the axial cross sectional slice.
Supernumerary tooth adjacent to teeth 33 and 34
A supernumerary tooth that resembles a premolar is positioned palatally to the roots of teeth 33 and 34. The crown of this tooth is positioned against the lingual surface of the mandibular alveolar process, and the developing root is approximately 70% formed. The supernumerary tooth has not caused any damage to the roots of the adjacent erupted teeth.
3. Bone dysplasia apical to tooth 33
The bone apical to tooth 33 exhibits a granular heterogeneous radiopaque pattern with a densely radiopaque central focus. The round shape of this entity, and the corticated periphery is suggestive of a localized bone dysplasia that is an incidental finding. However, this region should be radiographically monitored to ensure that there are no size changes over time.
The periodontal ligament space associated with tooth 33 is intact and normal adjacent to this entity.
Supernumerary tooth lingual to the roots 42 and 43
A supernumerary tooth positioned lingually to the roots of teeth 42 and 43. The crown of the supernumerary tooth is positioned adjacent to the cervical thirds of the roots of these teeth at the lingual aspect of the mandibular alveolar process. The root of the tooth is approximately 80% formed. No damage has occurred to the roots of teeth 42 and 43.
Axial slices of anterior mandible
These axial cross sectional images demonstrate the palatal positions of the two supernumerary teeth in the anterior mandible. The follicle that contains the tiny odontomes is visible between the roots of teeth 33 and 34.
