Vestibular/Buccal/Labial

Vestibular is the correct term referring to the surface of the tooth facing the vestibule or lips; buccal and labial are acceptable alternatives. The term “facial” specifically refers to the surfaces of the rostral teeth visible from the front. According to Dr. A.J. Bezuidenhout, a veterinary anatomist at Cornell University, “facial” is a bit of a misnomer. Traditionally “facial” has been used in human dentistry for the aspect of teeth visible from the front, i.e. incisors and canines.

Lingual/Palatal

Lingual: The surface of a mandibular or maxillary tooth facing the tongue is the lingual surface. Palatal can also be used when referring to the lingual surface of maxillary teeth.

Mesial/Distal

Mesial and distal are terms applicable to tooth surfaces. The mesial surface of the first incisor is next to the median plane; on other teeth it is directed toward the first incisor. The distal surface is opposite from the mesial surface.

Rostral/Caudal

Rostral and caudal are the positional and directional anatomical terms applicable to the head in a sagittal plane in non‐human vertebrates. Rostral refers to a structure closer to, or a direction toward, the most forward structure of the head. Caudal refers to a structure closer to, or a direction toward, the tail (Figures 1.36 and 1.37) (Illustration 1.2).
