Code	Display	Definition
M	Mesial	The surface of a tooth that is closest to the midline (middle) of the face.
O	Occlusal	The chewing surface of posterior teeth.
I	Incisal	The biting edge of anterior teeth.
D	Distal	The surface of a tooth that faces away from the midline of the face.
B	Buccal	The surface of a posterior tooth facing the cheeks.
V	Ventral	The surface of a tooth facing the lips.
L	Lingual	The surface of a tooth facing the tongue.
MO	Mesioclusal	The Mesioclusal surfaces of a tooth.
