|
|
a small cusp or tubercle on the lingual face of the tooth
|
Cingule
|
|
the ridge or tubercle on the lingual face of the tooth near the gingival
|
Cingulum (pl. cingula)
|
|
the portion of crown visible in oral cavity
|
Clinical crown
|
|
that region of the mesial or distal surface that touches the adjacent tooth in the same arch
|
Contact area
|
|
of or pertaining to a crown; applied by some to the occlusal surface
|
Coronal
|
|
the sinous cusps or enamel ridges on the molars of herbivore; a projecting ridge or structure
|
Crest
|
|
that portion of the tooth covered with enamel, which is normally visible in the oral cavity. See anatomic and clinical crown
|
Crown
|
|
a pronounced elevation on the occlusal surface

Cusp
|
|
elevations which extend in a mesial and distal direction from cusp tips. They form the buccal and lingual margins of the occlusal surfaces of posterior teeth.
|
Cusp Ridges
|
|
calcareous bodies which serve the purposes of teeth; a concretion which develops in the dental pulp as a part of the aging process.
|
Denticles
|
|
marks the fushion areas between adjacent cusps and other major parts of a tooth
|
Developmental groove
|
|
a “V-shpaed” space between the proximal surfaces of two adjoining, contacting teeth
|
Embrasure
|
|
a cleft or crevice in a tooth surface resulting from the imperfect fusion of the enamel of the adjoining cusps or lobes
|
Fissure
|
|
a passage perforating hard tissues that transmits either vessels and
or nerves |
Foramen (foramina)
|
|
a shallow depression or concavity on the surface of the tooth (see central f, lingual f, triangular f)
|
Fossa
|
|
the region of a multi-rooted tooth where the roots divide
|
Furcation
|
|
a shallow, linear depression on the surface of a tooth (see supplemental g, developmental g)
|
Groove
|
|
The incisal portion of an anterior tooth.
|
Incisal Ridge
|
|
A broad, shallow depression on the lingual surface of an incisor or canine.
|
Lingual Fossa
|
|
A division of a tooth crown formed from a distinct point of calcification.
|
Lobe
|
|
A rounded or conical prominence on the incisal ridge of a newly erupted incisor.
|
Mamelon
|
|
Elevated crests which form the mesial and distal margins of the occlusal surfaces of the posterior teeth, and the lingual surfaces of the anterior teeth.
|
Marginal Ridges
|
|
A place in which something is nurtured
|
Nidus (pl. Nidi)
|
|
An elevated crest comprised of the triangular ridge of the distobuccal cusp and the distal ridge of the mesiolingual cusp.
|
Oblique ridge
|
|
A sharp depression usually located at the junction of two or more developmental grooves or at the termination of a single developmental groove.
|
Pit

|
A depression extending longitudinally on the mesial or distal surface of a root.
|
Proximal root concavity
|
|
The narrow area of the pulp chamber within the root. (Root canal).

Pulp canal
|
|
The expanded cavity within the tooth that contains the pulp.
|
Pulp chamber
|
|
A liner elevation on the surface of a tooth.
|
Ridge

|
Sulcus
|
|
An indistinct liner depression, irregular in extent and direction that does not demarcate major divisional portions of a tooth.
|
Supplemental groove
|
|
The triangular ridges of a buccal and a lingual cusp that join to form a more or less continuous elevation extending transversely across the occlusal surface of a posterior tooth.
|
