Canaray 172761

Impacted tooth 11 with significantly malformed root

Tooth 11 is inverted and impacted. The cusp tip of tooth 11 has partially erupted through the buccal aspect of the alveolar process. The residual follicle surrounding the crown of the tooth appears hyperplastic and is continuous with the follicle surrounding the crown of the unerupted tooth 13. The root of tooth 11 is significantly malformed and is essentially nonexistent. This tooth has a hopeless prognosis, as it is devoid of root support. Tooth 11 can be surgically accessed from the buccal or palatal aspect of the alveolar process.

Axial views of tooth 11

These axial cross-sectional images demonstrate the hyperplastic follicle surrounding the crown of tooth 11. The root of tooth 11 has not yet commenced development.

Malformed tooth 13

Tooth 13 exhibits significant malformation of its crown and root. In particular, 90% of the root of tooth 13 has not formed. This tooth has a hopeless prognosis.

Malformed microdont tooth 12

Tooth 12 has a significantly malformed root, and a very high crown to root ratio, which suggests that the prognosis for this tooth is poor. The crown of tooth 13 is positioned distobuccally to the apical half of the root of tooth 12

Malformed tooth 14

Tooth 14 exhibits a malformed crown and a short malformed root. This tooth has a hopeless prognosis, and will not likely be functional.

Malformed root of tooth 21

Tooth 21 exhibits a very high crown to root ratio, due to the malformation of its root. The tooth has a poor prognosis, as a result.

Axial views of the anterior 1st quadrant

These axial cross-sectional images demonstrate the position of the inverted and impacted tooth 11, and the absence of any significant root formation of the tooth. The significant malformations of the roots of teeth 12, 13, 14 and 21 would likely result in the premature loss of these teeth as well.

**should add image of 13

Significantly malformed tooth 12

The crown of tooth 12 has an unusual morphology and the tooth is a microdont. In addition, the root of the tooth has been substantially malformed, and would be incapable of supporting the crown. This tooth has a hopeless prognosis.
