surface

[sur´fas]

the outer part or external aspect of a solid body; called also facies.

buccal surface the vestibular surface of the molars and premolars, which faces the cheek.

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.

masticatory surface occlusal 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.

The changes in C, O, Cl, F, Ca, P, and Ca/P ratio were evaluated on the occlusal surface by EDS as atomic percentages (at%), which allows us to determine directly the present number of atoms per element, unlike the weight percentage (wt%), which varies per element.

The occlusal surfaces show pitting, scratching and enamel chipping of antemortem origin, indicating the intense use of the teeth.

Neanderthals used 'toothpicks to alleviate pain of gum disease'

The left first permanent molar had been extracted previously as part of the orthodontic treatment plan and cavitation in the occlusal surface was noted when the tooth was partially erupted.

The teeth were worn down to create u-shaped grooves on the occlusal surfaces. Similar dental wear patterns have been documented on individuals who habitually pulled fibrous material through their teeth while weaving or spinning.

These include reduction of the absolute size of the face, pronounced supraorbital tori, nonprojecting chins, relative megadontia, expansion of the occlusal surface of the premolars, rotation of teeth within the maxilla and mandible, and dental agenesis.
