OROFACIAL ANATOMY EXAM 1 REVIEW QUESTIONS
Dentition - Answer -the term used to describe the natural teeth in the jaws.
Two Types of Dentition's - Answer -Primary and Permanent
Primary Dentition - Answer -deciduous, baby, milk, and temporary teeth
The amount of teeth found in the primary dentition - Answer -20 teeth total
8 Incisors
4 Canines
8 Molars
Permanent Dentition - Answer -the second dentition to develop
The amount of teeth found in the permanent dentition - Answer -32 teeth total
8 Incisors
4 Canines
8 Premolars
12 Molars
Non-succedaneous - Answer -Do not succeed another tooth because there is no tooth
ahead of them to come in. EX Molars
Eruption - Answer -Process of tooth coming into the mouth where you can see it.
Begins when tooth moving through bone. Visibly will continue until it reaches its
antagonist.
Active Eruption - Answer -Vertical tooth movement through tissue. OCCURS
THROUGHOUT LIFE.
Passive Eruption - Answer -No actual tooth eruption; apical movement of soft tissue. Ex
RECESSION
Incisors - Answer -function as instruments for BITING and CUTTING food because of
triangular proximal form.
Canines - Answer -tapered shape and prominent cusps function to PIERCE and TEAR
food
Premolars - Answer -Only in PERMANENT DENTITION, function to assist molars in
GRINDING, because of broad occlusal surface
Assist canines in PIERCING and TEARING food with their cusps
, Molars - Answer -function in GRINDING food
Tooth Designation Systems - Answer -Universal System
International Standards Organization System (ISO)
Palmer Notation Method
Universal Tooth Designation System - Answer -Tooth Designation System most widely
used in the United States because of its adaptable to electronic data transfer.
International Standards Organization Designation System (ISO) - Answer -Used by the
World Health Organization
Palmer Notation Method - Answer -Military tooth numbering system, used in
orthodontics.
Dentition Periods - Answer -There are only two dentition, but there are three dentition
periods
Primary Dentition Period - Answer -1st Period
6 mo- 6 yrs
Begins with the eruption of the primary mandibular central incisors.
Mixed Dentition Period - Answer -2nd Period (Ugly Duckling Stage)
6yrs - 12 yrs
shedding of primary teeth and eruption of permanent teeth
Permanent Dentition Period - Answer -Final Period
Begins with shedding of last primary tooth
usually begins after 12 years of age
alveolus (aveoli) - Answer -tooth socket
alveolar process - Answer -where each aveolus is located; tooth bearing part of the
jaw, also considered a dental arch ( maxillary, mandibular)
Occlusion - Answer -the method where the teeth of the mandibular arch and the
maxillary arch come into contact
D-A-Q-T System - Answer -D= Dentition
A= Arch
Q= Quadrant
T= Tooth Type
Anterior Teeth - Answer -Incisors and Canines; closer to midline
Posterior Teeth - Answer -Molars and premolars; farther from the midline
