Enamel, Dentin, Cementum, pulp - CORRECT ANSWER what are the four histological structures of a
tooth?
Anatomical crown - CORRECT ANSWER what is the portion of the tooth that extends from the incisal or
occlusal surface to the enamels junction with the cementum of the root?
clinical crown - CORRECT ANSWER what is the visible portion of the anatomical crown extending from
the crest of the soft tissue and includes the occlusal surface or incisal edge?
contact area - CORRECT ANSWER what is the point or area where approximating teeth in the same arch
touch or meet each other?
embrasures - CORRECT ANSWER what is the spaces adjacent to and surrounding the contact of the
teeth in the same arch?
incisal or occlusal, facial or buccal, lingual, gingival - CORRECT ANSWER what are the four embrasure
areas that surround the proximal contact area?
enamel - CORRECT ANSWER what covers the anatomical crown of the tooth and varies in thickness in
different areas of the tooth?

cementoblasts - CORRECT ANSWER what forms cementum?
false - CORRECT ANSWER acellular cementum is located at the apex of a root and can regenerate itself if
damaged or removed.

furcation - CORRECT ANSWER what is the division of multiple roots?
marginal ridges - CORRECT ANSWER what is the rounded mesial and distal borders of enamel found on
the occlusal surface of posterior teeth and on the linguals of anterior teeth?

spillway - CORRECT ANSWER what is the very small depression extending across marginal ridges on the
posterior teeth?
fissures - CORRECT ANSWER what is the incomplete closure of enamel that appears as faint, thin
grooves?

teeth?
the gingival unit - CORRECT ANSWER which part of the periodontium consists of free and attached
gingiva and the alveolar mucosa?
the attachment apparatus - CORRECT ANSWER which part of the periodontium consists of the
cementum, periodontal ligaments and alveolar process?

tooth called what?
the interdental papilla - CORRECT ANSWER which portion of the free gingiva is located in the
interproximal areas?
