The canines are responsible for __________ food.
What do the premolars do?
assist molars and canines
The molars broad occlusal surface helps them to _______?
Tooth Numbering is used to identify teeth for:
treatment, identification, and documentation
Universal Tooth Designation System
most widely used
Primary teeth (universal)
Designated by the capital letters A-T consecutively and clockwise
Permanent teeth (universal)
Designated by the numbers #1-#32 consecutively and clockwise
International Standards Organization Designation System (ISO System)
uses a 2 digit code, 1st digit indicates the quadrant, and the 2nd digit indicates the tooth in the quadrant

The dentition has _____ stages/states
The dentition has ____ types.
Stages of dentition
primary, mixed, and permanent
what is usually the first tooth of the primary dentition to erupt?
mandibular central incisors
what is usually the first tooth of the permanent dentition to erupt?
mandibular first molar
When does the mixed dentition stage usually occur?
bone of tooth socket that surrounds and supports each tooth
tooth bearing part of jaw bone where each alveolus is located
incisors and canines; teeth located in the anterior part of the mouth
both alveolar processes of the jaw bones---- the maxilla and mandible
teeth in the mandibular arch of the lower jaw bone and mandible
teeth in the maxillary arch of the upper jaw bones or maxillae
and imaginary vertical plane that divides each dental arch into two approximately equal halves (a right and a left half)
the anatomic alignment of teeth and their relationship to the rest of the masticatory system; how the teeth of the mandibular arch contact those of the maxillary arch
molars and premolars; teeth located in the posterior part of the mouth
a division of each dental arch into two parts based on the relationship to the midline; four sections make up the oral cavity
a division of each dental arch into three parts based on the relationship to the midline; six ________ make up the oral cavity
the part of the tooth composed of dentin covered by enamel (part you cant see)
the part of the tooth composed of dentin covered by cementum (part you cant see)
the part of the tooth where the enamel of the crown and cementum of the root typically meet
cementoenamel junction (CEJ)
the part of the anatomical crown that is visible and not covered by gingiva
the part of the anatomical root that is visible and not covered by gingiva
area where adjacent tooth crowns in the same arch physically touch on each proximal surface.
a major elevation on the masticatory surface of canines and posterior teeth
spaces that occur when two teeth in the same arch contact at the crown curvatures; they are continuous with the interproximal spaces
surfaces closest to the lips and inner cheeks; termed labial if nearest lips and buccal if nearest cheeks
the greatest elevation of the tooth, either incisocervically or occlusocervically, on a specific surface of the crown
height of contour or crest of curvature
area between adjacent tooth surfaces
raised areas on masticatory surfaces that are named according to their location (i.e., lingual, buccal, mesial, distal)
linear elevations or ridges
surfaces closest to the tongue are termed lingual; lingual surfaces closest to the palate are also termed palatal
the junction of three crown surfaces
include both mesial and distal surfaces between adjacent teeth
is covered by the inner part of the dentin of both the crown and roots and includes the pulp chamber, pulp canals, apex, apical foramen, and possibly the pulp horns.
an imaginary line that represents the long axis of a tooth; drawn through the apex of the root and the subsequently through the crown, bisecting the CEJ
root axis line (RAL)

3 labial and 1 lingual
Are the largest incisors and crown is the widest of any tooth
#8 and #9
