surface

 [sur´fas]

buccal surface the vestibular surface of the molars and premolars, which faces the cheek.
contact surface proximal surface.
distal surface the surface of a tooth that is farthest from the midline of the dental arch, opposite to its mesial surface.
facial surface vestibular surface.
incisal surface the cutting edges of the anterior teeth, the incisors and canines, which come into contact with those of the opposite teeth during protrusive occlusion. See also occlusal surface.
labial surface the vestibular surface of the incisors and canines, which faces the lips.
lingual surface the surface of a tooth that faces inward toward the tongue and oral cavity, opposite the vestibular surface; called also oral surface.

mesial surface the surface of a tooth that is closest to the midline of the dental arch, opposite to its distal surface.
occlusal surface the surface of the teeth that comes in contact with those of the opposite jaw during occlusion; called also masticatory surface.
oral surface lingual surface.
proximal surface (proximate surface) the area where the mesial surface of one tooth touches the distal surface of another; called also contact area or surface.
vestibular surface the surface of a tooth that is directed outward toward the vestibule of the mouth, opposite to the lingual surface; see also buccal surface and labial surface. Called also facial surface.

occlusal surface

Etymology: L, occludere, to close up, superficies, surface
the chewing surface of a primary or secondary posterior tooth in one arch that makes contact or near contact with the corresponding surface of a tooth in the opposite arch. Also called masticatory surface.
