and lacking in the other, we cannot assess its length relatively to the length of the crown. The base of the root is large. The root labiolingual width is stable along the preserved section, practically equivalent to the crown mesiodistal basal length, and slightly inferior to the maximum width of the crown. The root is labiolingually narrower than mesiodistally wide. In lingual and labial views, it has subparallel and slightly convex borders. At the fracture point, the root has an oval cross-section with a large pulp cavity.
