Configurations of pulp horns and root canals in maxillary and mandibular third molars (Triadan 11). Scale bar: 5 mm. Maxillary 111, 11.5 years: One mesial and one distal pulp compartment is present. Pulp horn 7 is connected to the adjacent pulp horn 2. Solid arrow (a): Isolated pulp horn 8. Arrowheads (a, p2): Furcation of root canals II and III. Mandibular 311, 13.5 years: Three pulp compartments are only developed in Triadan 11s. Root canal I solely contributes to pulp horns 1, 3 and 4; root canal II solely contributes to pulp horns 2 and 5. The third pulp compartment comprises root canal III which is connected to pulp horn 7. Both distal root canals II and III are placed in the elongated distal root.
