Supernumerary tooth lingual to teeth 35 and 36

A supernumerary tooth that resembles a mandibular premolar is developing vertically in the lingual aspect of the alveolar process in the interradicular region of teeth 35 and 36. This supernumerary tooth has not caused any root resorption or damage to teeth 35 and 36. The crown of the tooth is positioned at the alveolar crest. The root of the tooth is fully formed. The periodontal ligament space is of uniform width around the root of the tooth, which suggests that the tooth is not ankylosed. The tooth can be surgically accessed from the lingual aspect of the alveolar process in the interradicular region of teeth 35 and 36.

Axial views of supernumerary tooth in third quadrant

These axial cross-sectional images demonstrate the normal appearance of the alveolar bone that surrounds the root of the fully formed supernumerary tooth in the interradicular region of teeth 35 and 36. Note the absence of any root resorption or damage to these teeth.

Normal tooth 36

Tooth 36 has not been affected by the supernumerary tooth that is developing mesiolingually to its mesial root.

Normal tooth 35

Tooth 35 has not been affected by the supernumerary tooth that is developing distolingually to its root. No resorption or damage is present at tooth 35.

Axial views of mid-third quadrant

These axial cross-sectional images demonstrate the lingual position of the supernumerary tooth in the alveolar process in the interradicular region of teeth 35 and 36.

Supernumerary tooth 4a exhibiting gemination

A supernumerary tooth is present in the mid-fourth quadrant in the region lingual to tooth 45. This supernumerary tooth exhibits gemination in its coronal region. The root of the supernumerary tooth is almost fully formed. The tooth has slightly buccally displaced the root of tooth 45, but has not had any other effects on the surrounding structures. This supernumerary tooth can be surgically accessed from the lingual aspect of the alveolar process adjacent to tooth 45.

Axial views of tooth 4a

These axial cross-sectional images demonstrate the lingual position of the supernumerary tooth 4a relative to the buccally displaced root of tooth 45. Note the absence of any root resorption or damage to tooth 45.

Buccally displaced tooth 45

The root of tooth 45 has been slightly buccally displaced in the alveolar process by the supernumerary tooth 4a that is positioned lingually to it. Tooth 45 appears normal otherwise.

Supernumerary tooth 4b lingual to teeth 43 and 44

A supernumerary tooth (4b) is positioned at the lingual aspect of the alveolar process in the interradicular region of teeth 43 and 44. This vertically oriented supernumerary tooth resembles a mandibular premolar and has not caused any root resorption or damage to the adjacent teeth. The crown of this tooth is positioned at the lingual aspect of the alveolar crest between teeth 43 and 44.

Normal tooth 44

Tooth 44 has not been significantly affected by the supernumerary teeth 4a and 4b that are positioned distolingually and mesiolingually, respectively, to its root. No root resorption or damage has occurred to tooth 44.

Normal tooth 43

Tooth 43 appears normal radiographically and has not been affected by the supernumerary tooth 4b that is positioned distolingually to it. No root resorption or damage is present at tooth 43.

Axial views of mid-fourth quadrant

These axial cross-sectional images demonstrate the lingual positions of teeth 4a and 4b in the mid 4th quadrant in the interradicular regions of teeth 43, 44, and 45.
