Morphology Questions with Detailed
Verified Answers
Question: Teeth are identified by their location and name, please describe.
Answer: arch, quadrant, name
Question:
Describe the Universal Numbering System for permanent teeth
Answer: Begins from the upper right third molar, continues to the left
numbered 1-16. Then continued onto the lower left third molar, around to the
lower right third molar numbered 17-32.
Question:
Describe the Federation Dentaire International System for permanent teeth
Answer: The FDI numbering system identifies teeth by quadrant,then
number. Quadrants are listed as 1-4, UR(1) UL(2) LL(3) LR(4). Teeth are
number 1-8 from midline to posterior. 1- central incisor 3- canine 8- third molar
Question:
location
Answer: Surfaces of teeth are identified by their

Question:
central incisors at the midline
Answer: The only place where two mesial surfaces come in proximal contact
is between
Question:
anterior and posterior
Answer: Teeth are divided into two main groups:
Question:
anatomical crown
Answer: The portion of the tooth that extends from the incisal or occlusal
surface to the enamel's junction (CEJ/ cervical line)
Question:
Cementoenamel junction (CEJ/ Cervical Line)
Answer: This appears as a slight constriction that encircles the tooth, dipping
apically (toward the root tip) on the facial and lingual surfaces and rising
coronally (toward the occlusal surface) at the proximal contacts. Variation in
location is likely, and should be noted to dictate the contours of the
restorations placed in this area.
Question:
clinical crown
, Page | 3
Answer: This portion of the tooth is the visible portion of the anatomical
crown extending from the crest of the soft tissue and includes the occlusal
surface/incisal edge.
Question:
clinical crown
Answer: The length of which part of the crown influences the selection of a
matrix and the final contours of a restoration?
Question:
Furcation
Answer: The area where the roots of a tooth divide is called
Question:
Furrow
Answer: Coronal to the actual division into two+ roots is a concavity that
extends to or nearly to the cementoenamel junction, this is called the
Question:
overcontouring the restoration
Answer: When restoring in or near the furrow, the operator must be aware of
the anatomy of the concavity and the surrounding tooth structure to avoid
