Crown - answer✔Part of a tooth composed of dentin and pulp covered by enamel.
Root - answer✔Part of a tooth composed of a pulp cavity and dentin covered by cementum.
Bulkier on the facial surface than on the lingual surface and tapers more dramatically on the
lingual surface.
Anatomical Crown - answer✔Part of the crown covered by enamel. It remains constant
throughout the life of the tooth.
Anatomical Root - answer✔Part of the root covered by cementum; the part of a tooth that is
embedded in the jaw and is not exposed to the oral cavity.
Clinical Crown - answer✔Part of the anatomical crown that can be seen in the oral cavity; not
covered by gingival tissue. It's height is determined by the location of the marginal gingiva. It
can change over time especially with gingival recession.
Clinical Root - answer✔Part of anatomical root visible in the oral cavity; not covered by gingival
tissue; may vary over time due to gingival recession.
Cervical Line - answer✔Same as: CEJ (cementoenamel junction); the area where the line is
formed seperating the crown from the root.
Eruption - answer✔The act of a tooth moving occlusally and becoming visible in the mouth as it
emerges through the gum tissue.
Dentition - answer✔Natural teeth in the jaw of either primary and permanent teeth or mixed
grouping of teeth; all maxillary and mandibular teeth.
Incisors - answer✔Anterior teeth that function as instruments for biting and cutting food during
mastication because of their triangular proximal form.
Canines - answer✔Anterior teeth that function as instruments to tear or pierce food durning
mastication because of their tapered shape and prominent cusp.

Premolars - answer✔Posterior teeth found only in the permanent dentition, they function to assist
in grinding food during mastication; they have a broad occlusal surface and prominent cusps.
Molars - answer✔Posterior teeth with the largest and strongest crowns that funchtion in grinding
food during mastication; they have wide occlusal surfaces and prominent cusps.
Cusp - answer✔A point, or peak on the occlusal surface of a molar or premolar and on the incisal
edge of a canine. This consists of one or more major elevations on masticatory surface of the
canines and posterior teeth.
Enamel - answer✔Hard shiny outer layer of tooth that covers the anatomical crown.
Cementum - answer✔dull yellow surface of the anatomical root; is the outermost layer of the
root of the tooth.
Mastication - answer✔The process of biting and grinding food in your mouth so it becomes soft
enough to swallow.
Convex - answer✔The surface of a tooth that curves or bulges outward.
Concave - answer✔The surface of a tooth that curves or bends inward.
Pulp Horns - answer✔Extensions of coronal pulp into cusps of posterior teeth.
Pulp Chamber - answer✔Part of the tooth containing the largest mass of pulp.
Apical Foramen - answer✔Opening at the apex of the root of a tooth through wich the nerve and
blood vessels that supply the dental pulp pass.
Upper Arch - answer✔Maxillary arch
Lower Arch - answer✔Mandibular arch
Maxilla - answer✔The upper jaw that holds the upper teeth in place.
Mandible - answer✔The lower jaw that holds the lower teeth in place.
Anterior Teeth - answer✔Include the central and lateral incisors along with the canine teeth;
located in the front of the mouth.
Posterior Teeth - answer✔Include all of the molars in the primary dentition as well as the
premolars and molars of the permanent dentition; located in the back of the mouth
