Incomplete gemination of tooth 35: inseparable
Tooth 35 exhibits incomplete gemination, resulting in fused buccal (35B) and lingual (35L) segments that are connected by a central isthmus. The position of the buccal segment of tooth 35 within the dental arch is most reflective of the normal orientation expected for the second premolar tooth. Also, the crown of the lingual segment of tooth 35 is slightly smaller than that of the buccal segment. The pulp canals within the buccal and lingual segments of tooth 35 communicate through a central isthmus at the midroot level, which may preclude the separation of the two segments. The roots of the buccal and lingual segments of tooth 35 are fully formed and the periodontal ligament space is visible around the entire root circumference, which suggests this tooth is not ankylosed. The left mandibular nerve and mental foramen are located apical to the buccal root apex of tooth 35. Tooth 35 has not had any affect on the mandibular nerve.
Axial views of tooth 35
These axial cross-sectional images demonstrate the incomplete gemination of tooth 35, resulting in the presence of buccal and lingual segments which are connected by a central isthmus. The pulp chambers of the two segments are also connected by a central isthmus at the midroot level of tooth 35.
Coronal views of tooth 35
These coronal cross-sectional images demonstrate the presence of a central isthmus connecting the pulp chambers of the buccal and lingual segments of tooth 35.
Sagittal views of tooth 35
These sagittal cross-sectional images demonstrate complete root formation of the buccal and lingual segments of tooth 35. The periapical region of tooth 35 appears normal.
