Figure 7

Morphology of pulp horns and root canals in mandibular cheek teeth. Arabic numerals (1 to 7): Pulp horns. Roman numerals (I to III): Root canals. Colours indicate separate pulp compartments. (a) 3D images of the pulp cavity. Inserted planes p1 to p6 render the position of selected 2D Ī¼CT images, coloured planes indicate locations of connections. Sections (p1 - p6) demonstrate cross-sectional shape and size of pulp horns and root canals. Dark grey: Pulp tissue; light grey: Dentine and cementum; white: Enamel; rmā€‰=ā€‰mesial root, rdā€‰=ā€‰distal root. Scale bar: 5 mm. No segmentation (Triadan 409, 15 years): A narrow common pulp chamber connects all five pulp horns. Two distinct root canals are developed. Maximal segmentation (1) (Triadan 407, 7 years): Two pulp compartments are present, with pulp horn 4 included in the distal pulp compartment. Root canal I solely contributes to pulp horns 1 and 3. Root canal II solely contributes to pulp horns 2, 4 and 5. Maximal segmentation (2) (Triadan 407, 5 years): Two pulp compartments are displayed, with pulp horn 4 connected to the mesial pulp compartment. Root canal I solely contributes to pulp horns 1, 3 and 4. Root canal II solely contributes to pulp horns 2 and 5.
