48 Cards in this Set

  • Front
  • Back
A small cell or cavity, hence a tooth socket, alveolus dentalis
portion of tooth covered with enamel
Anatomic crown
a division into 2 parts, as any two roots of a tooth
an accessory cusp often noted on the lingual surface of the maxillary molar mesiolingual cusp
Carabelli’s cusp
a relatively broad deep angular valley in the central portion of the occlusal surface of a molar
Central Fossa
a line formed by the junction of enamel and cementum (CEJ)
Cervical line
a narrow or constricted portion of a tooth in the region of the junction of crown and root
Cervix (pl. cervices)
a small cusp or tubercle on the lingual face of the tooth
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
the sinous cusps or enamel ridges on the molars of herbivore; a projecting ridge or structure
that portion of the tooth covered with enamel, which is normally visible in the oral cavity. See anatomic and clinical crown
a pronounced elevation on the occlusal surface
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.
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
a cleft or crevice in a tooth surface resulting from the imperfect fusion of the enamel of the adjoining cusps or lobes
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)
the region of a multi-rooted tooth where the roots divide
a shallow, linear depression on the surface of a tooth (see supplemental g, developmental g)
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.
A rounded or conical prominence on the incisal ridge of a newly erupted incisor.
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.
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.
The portion of a tooth covered with cementum and normally embedded in the alveolar process.
See pulp canal.
Root canal
That portion or a multirooted tooth between the cervical line and furcation of the roots.
Root trunk
A fold or crease. The irregular ridges of the membrane of the palate.
Ruga (pl. rugae)
A small sac or cyst.
An elongated valley in the surface of a tooth formed by the inclines of adjacent cusps or ridges which meet at an angle.
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.
Transverse ridge
A shallow depression on the occlusal surfaces of posterior teeth located within the confines of the mesial or distal marginal ridges.
Triangular fossa
Prominent elevations, triangular in cross-section, which extend from the tip of a cusp towards the central portion of the occlusal surface of a tooth.
Triangular ridges
A division into three parts or branches, as the three roots of a maxillary first molar.
A small elevation on the crown of a tooth possibly by excessive accumulation of enamel.
