- the junction of 2 or more surfaces
- Angle
- toward the front of the body
- Anterior
- the terminal end or tip of the root
- Apex
- toward the apex of the root
- Apicle
- the contact relationship of the occlusal surfaces of the teeth during jaw movement
- Articulation
- pertaining to the longitudinally (long) axis of the tooth
- Axial
- next to or toward the cheek in posterior teeth
- Buccal
- toward the cheek
- Buccally
- from the posterior tooth surface facing the cheek to that facing the tongue
- Buccolingual
- junction of enamel and cementum; cervical line (CEJ)
- Cementoenamel Junction
- away from the median line
- Distal
-
the surface of the tooth facing away from the median line following the
curve of the dental arch - Distal surface
- relating to the distal and buccal portion of the tooth
- Distobuccal
- relating to the distal and lingual portion of the tooth
- Distolingual
- the labial and buccal surfaces collectively
- Facial surfaces
- The cutting edge of the anterior teeth, particularly the incisors.
- Incisal Surface
- Between adjoinging surfaces; the proximal surfaces.
- Interproximal
- Next to or toward the lips; of, or pertaining to the lips
- Labial
- The surface of an anterior tooth positioned immediately adjacent to the lip.
- Labial Surface
- From the anterior tooth surface facing the lips to the surface facing the tongue.
- Labiolingual
- That angle formed by the junction of two surfaces along a line, e.g., the mesiobuccal angle.
- Line Angle
- Next to or toward the tongue; pertaining to the tongue.
- Lingual
- The surface of a tooth which faces the tongue; opposite of the facial surface.
- Lingual Surface
- Toward the median line.
- Mesial
- The surface of a tooth facing toward the median line following the curve of the dental arch.
- Mesial Surface
- From the surface facing the midline to the surface facing away from the midline following the arch curvature.
- Mesiodistal
- A line passing through the center
- Midline
- To bring the mandibular tooth into contact with the maxillary teeth.
- Occlude
- Toward the biting surface of a posterior tooth; pertaining to occlusion.
- Occlusal
- The surface of a premolar or molar contained within the marginal and cusp ridges.
- Occlusal surface
- The relation between the incising and occluding surfaces of the maxillary and mandibular teeth when they are shut; Any contact between the incising or masticating surfaces of the teeth.
- Occlusion
- The angle formed by the junction of three surfaces at a point, e.g. the mesiolabioincisal angle.
- Point angle
- The surface of a tooth that faces toward an adjoining tooth in the same arch, i.e., the mesial or distal surfaces.
- Proximal surface
- Imaginary divisions of a tooth crown or root as to length (i.e., occlusal, middle, and gingival thirds) or mesiodistal breadth (i.e. mesial, middle, and distal thirds).
- Thirds
