From: Three-dimensional anatomy of equine incisors: tooth length, enamel cover and age related changes
3D model of incisors, showing the not uniform tube like enamel cover. a, b, c Triadan 201 (please also see Additional video file 1) with symmetric indentations (black arrows) and most apical points of the enamel cover (black and white arrow heads) located in the sagittal plane of the tooth. d, e, f Triadan 103 (please also see Additional video file 2) with the mesial incision (d, black arrow) reaching further occlusal than the distal one (f, black arrow) and the most apical points of the enamel cover located parasagittal (black and white arrow heads). White = enamel cover, transparent = dental root composed of dentin and cementum, red = pulp cavity, black arrows = mesial and distal incision of the enamel cover, black arrow head = most apical point of the palatal enamel cover, white arrow head = most apical point of the labial enamel cover.
