32 teeth total. 16 upper and 16 lower
What are successional teeth
Permanent teeth that replace deciduous teeth
*Permanent molars, which replace nothing, are called accessional teeth
Humans have what two types of dentition? Define them
Diphyodont: develop two sets of teeth

Review this
Arch Form is what shaped
U-shaped
*The maxilla is bigger than the mandible
The arch form is determined mostly by
underlying basal bones
Compare overjet vs overbite
Overjet is horizontal overlap
Overbite is vertical overlap
Define curve of spee
cusp tips follow an upwards curve in lateral view

curvature of the maxillary teeth is convex in frontal view
What is the anatomical and clinical crown?
Anatomical: covered with ENAMEL
Clinical: portion of anatomical crown that is visible clinically
What is anatomical root and clinical root?
Anatomical: portion of the tooth that is covered with cementum
Clinical: port of the root that is embedded in the jaw
Define cervical line
Line that separates the anatomic crown from the anatomic root
-junction between enamel and cementum (CEJ)
Define pulp cavity
space in the tooth that contains the pulp or “nerve” of the tooth
- it has a coronal (crown) portion and a radicular (root) portion, usually called the root canal
What are the 4 types of tooth tissue
- Enamel
- Dentin
- Cementum
- Pulp
The protective outer surface of the anatomic crown.
It is 96% mineral and is the hardest tissue in the body
ENAMEL
Located in both crown and root, it makes up the bulk of the tooth beneath the enamel and cementum.
Dentin
What lines the pulp cavity
Dentin
-This substance covers the surface of the anatomic root
-It facilitates anchorage of the tooth in its bony socket (the alveolus)
Cementum
-The central, innermost portion of the tooth
-It has formative, sensory, nutritive, and reparative functions during the life of the tooth
Pulp
Define midline
An imaginary line on the plane that bisects the dental arch at the center
Define Mesial
toward the center midline of the dental arch
Define distal
Away from the center midline of the dental arch
Define proximal
the surface of a tooth that is toward another tooth in the arch
Define facial
toward the cheeks or lips `
Define labial
facial surface of anterior teeth (toward the lips)
Define Buccal
facial surface of posterior teeth (towards the cheeks)
Define Lingual
Toward the tongue
Define Occlusal
The biting surface; that surface that articulates with an antagonist tooth in an opposing arch
Define Inciscal
The cutting edge of anterior teeth
Define apical
toward the apex, the tip of the root
Define contact
a point or area where one tooth is in contact with its neighbor
Know this well
Define cusp
A point or peak on the occlusal surface of MOLAR and premolar teeth and on the inciscal ridges of canines
a bulge or elevation on the lingual surface of incisors or canines. It makes up the bulk of the cervical third of the lingual surface
the cingulum
Define Lobe
primary centers of formation in the development of the crown of the tooth
-cusps and mamelons are represented of lobes
define mamelons
lobes seen on anterior teeth; any of the three rounded protuberances seen on the unworn surfaces of an incisor
What are the four types of ridges?
- Marginal ridges
- Triangular ridges
- Transverse ridges
- Oblique ridges
Define marginal ridge and where its located
round borders of enamel that form the margins of the surfaces of premolars and molars, mesially and distally, and the mesial and distal margins of the incisors and canines lingually
okay so
1. Incisors and canines: lingual outer border
2. Molars and premolars: mesially and distally
Where are TRIANGULAR ridges found
Ridges that descend from the tips of molars and premolars towards the central groove of the occlusal surface
*remember molar and premolar only
Where are TRANSVERSE ridges found and how are they created
created when a buccal and a lingual triangular ridge join
* it is the union of two triangular ridges crossing transversely across the surface of a posterior tooth
Where are OBLIQUE ridges found
-Seen on maxillary molars and are a companion feature to the distal oblique groove
Location of central fossa
found on the occlusal surface of a molar. Formed by the converging of ridges terminating at a central point in the bottom of a depression where there is a junction of developmental grooves
what is the lingual fossa
sulcus on the lingual surface of INCISORS
Where are triangular fossae found
found on molars and premolars on the occlusal surfaces mesial or distal to marginal ridges
A ______ is often the site of the onset of dental decay
a pit.
*a pit is a small pinpoint depression located at the junction of developmental grooves or at the terminals of these groups
A sharply defined, narrow and linear depression formed during tooth development and usually separates lobes or major portions of a tooth.
developmental groove
Describe the odontogram and explain its use
its a digital representation of the patient’s mouth, including existing restoration, pathology, and planned treatment
How do you add a treatment note to a procedure
Select “Add Tx Note”
The college of dentistry mostly uses _____ formatting
AMA
T or F: “And” in searches means within a concept
False.
And means both between 2 concepts
Or will always give you more (within a concept)
List 3 clinical tools you can use when doing research
- Dynamed
- Lexicomp/ clinical pharmacology

What is a wildcard in database searches
a character that substitutes for another character or string of characters when searching a database.
Example: Dent* =dentistry, dental, dentin, dented
