Colour-coding of canals in tooth 26
The four canals in tooth 26 were coloir-coded in the CBCT scan. The buccal canals are red, the distobuccal canal is green, and the palatal canal is blue. This is intended to assist with visualization of the calcified canals.
Occlusal view through access preparation demonstrating relative canal orifice positions
These occlusal cross-sectional images demonstrate the relative positions of the canal orifices in relation to the access preparation.
Taurodont tooth 26
Tooth 26 is a taurodont with a deep pulp chamber. The mesiobuccal and distobuccal root canals of tooth 26 are partially calcified. Two canals appear to be present in the mesiobuccal root of the tooth and a single canal is present in the distobuccal root. The access preparation should be slightly distobuccally extended in order to engage the partially calcified distobuccal root canal. The root fracture are present in tooth 26. No periapical pathology is radiographically evident.
Axial views of tooth 26
These axial cross-sectional images demonstrate the slight distobuccal extension of the access preparation that would be required in order to engage the partially calcified distobuccal root canal of tooth 26. Note the presence of two potential canals in the mesiobuccal root of the tooth, as well as single canals in the distobuccal and palatal roots.
Buccolingual views of tooth 26
These buccolingual cross-sectional images demonstrate the long pulp chamber of tooth 26, as well as the adequate endodontic access of the MB1 and palatal root canals. Note the absence of any periradicular pathology 26.
Mesiodistal views of tooth 26
These mesiodistal cross-sectional images demonstrate the normal appearance of the alveolar bone on the mesial and distal surfaces of the roots of tooth 26. The distobuccal root canal appears to be partially calcified.
