1. External resorption in accessory cusp of tooth 48

Tooth 48 is a morphologic variant with an accessory cusp on the distobuccal surface of its crown. This appears to be a case of germination. External resorption is present on the buccal surface of this accessory cusp at the level of the cemento-enamel junction.

Right mandibular nerve buccal to tooth 48DL+ML & lingual to tooth 48Bu

Tooth 48 is vertically oriented in the mesiodistal dimension, and is in linguoversion. Coronal resorption is present.The right inferior alveolar nerve canal passes buccally to the apex of the distolingual root of tooth 48, and is not compressed. The nerve passes buccally to the inferior aspect of the mesiolingual root of the tooth and is not compressed. The nerve courses lingually to the apex of the buccal root of the tooth and is not compressed. The adjacent tooth 47 exhibits caries, but does not exhibit resorption or displacement

Orthogonal views of geminated tooth 48

These orthogonal cross-sectional images demonstrate the dissemination that is present in the distal aspect of tooth 48, which has produced an accessory distal cusp. A common root canal system passes through tooth 48 and the geminated accessory cusp.

Axial views of tooth 48

These axial cross-sectional images of tooth 48 demonstrate the buccal passage of the nerve relative to the distolingual and mesiolingual roots of the tooth and the lingual passage of the nerve relative to the buccal root of the tooth.

Mesiodistal views of posterior 4th quadrant

These mesiodistal cross-sectional images of the posterior 4th quadrant demonstrate the vertical orientation of tooth 48 and the normal residual follicle surrounding the crown of the tooth. Note the presence of the accessory distobuccal cusp in tooth 48 and the resorption at the level of the cementoenamel junction of the accessory cusp. The adjacent tooth 47 exhibits caries, but does not exhibit resorption or displacement.
