Description
Original diagnose after Feichtinger et al. (2022) [31181]: Very small, labio-lingually compressed teeth with gradient monognathic heterodonty. Asymmetrical crown bent distally, but crown apex always erect. Mesial cutting edge sigmoid with pronounced curvature in the lower half of the crown. Distal cutting edge straight, connected basally to a short distal heel. Labial crown face flat with one prominent enameloid ridge following the contour of the mesial cutting edge. Lingual crown face convex but flattened towards the mesial and distal crown margins. Lingual root face with broad and high protuberance covering the lingual half of the basal root face. Medio-lingual and central foramina present. Labial crown-root edge straight with variable number and size of foraminal openings. Angular root morphology with notched labial edge of the basal root face. No distinct tooth-interlocking surface developed.
