CHAPTER 4: DENTAL ANATOMY EXAM
QUESTIONS AND ANSWERS 100% PASS
Anatomic crown - ANS The portion of the tooth covered with enamel. Remains the same size
throughout the life of the tooth, regardless of the position of the gingiva
Clinical Crown - ANS The portion of the tooth that is visible in the mouth. The length varies
during life cycle of the tooth, depending on the level of the gingiva
Cementum - ANS The root is the portion of the tooth that is normally embedded in the
alveolar process and is covered with
Bifurcation - ANS Means division into two roots
Trifurcation - ANS Means division into three roots
Apex - ANS The tapered (reduce in thickness toward one end) end of the root tip is known as
the
Apical - ANS Anything that is located at the apex is referred to as
Periapical - ANS Anything that is surrounding the apex is said to be

, Cementoenamel junction, CEJ - ANS Formed by the enamel of the crown and the cementum
of the root
Enamel - ANS Makes up the anatomic crown and is the hardest material of the body, thus
forming a protective covering for the underlying dentin
Enamel prisms, also known as enamel rods - ANS Enamel is composed of millions of calcified
Dentin - ANS Makes up the primary portion of the tooth and extends almost the entire length
of the tooth
Dentinal tubules - ANS Although hard, dentin is a very porous tissue made up of microscopic
canals called
Dentinal fiber - ANS Each dentinal tubules contains a
Pulp - ANS The inner aspect of the dentin forms the boundaries of the
Cementum - ANS Protects the tooth but is not as hard has either enamel or dentin
CEJ (cementoenamel junction) - ANS The cementum joins the enamel at the
Periodontium - ANS Supports the teeth in the alveolar bone
Periodontal ligaments - ANS Dense connective tissue organized into groups of fibers that
connect the cementum covering the root of the tooth with the alveolar bone of the socket wall
