Dentistry Flashcards
Incisor function
grip and/or cut
Canine function
hold and/or puncture or tear
premolar function
to hold/carry in some species, grind in others
molar function
shearing in some species, grinding in others
Name the bone and correlating tooth type for the upper arcade
incisive bone: I
maxillary bone: C, P, M
what are the cheek teeth
P and M
Name the bone and correlating tooth type for the lower arcade
Mandibular: I, C, P, M
What is a quadrant
side/half of an arcade
What is an arcade
All teeth in the upper or lower jaw
Describe the vestibular surface
Vestibular:
labial = rostral, near the lips (used with I and C teeth)
Buccal = caudal, near the cheeks (used with P and M teeth)
Describe the lingual surface
Facing the tongue, used in mandibular teeth
Describe the palatal surface
Facing the palate, used in maxillary teeth
Describe the mesial surface
Rostral (P,M) and Medial ( C,I) surface between teeth
Describe the distal surface
Caudal (P,M) and lateral (C,I) surface between teeth
What is the occlusal surface
the surface that
meets another tooth of the
opposite arcade
* Chewing or grinding surface
What is the crown
Visible part that extends beyond the gingiva or
“gums”
What is the neck
Constriction at base of crown, at the level of the gingiva (Cementoenamel junction)
What is the root
Located beyond the level of the attached gingiva, embedded in alveolar bone
What is the apex
Root tip
What is enamel and where on the tooth is it found
Hardest substance in the body
Superficially covers the Crown
Insensitive and does not regenerate
What is dentin and where on the tooth is it found
- Middle layer (is majority of dental tissue)
- Surrounds the pulp cavity
- Sensitive and regenerative
What is the cementum, where is it found, and what important structure is associated with it
Limited to the root
Fibers of the periodontal ligament extend from the cementum to the surrounding alveolar bone
What is the pulp, where is it found
Most internal portion of the tooth
Within the pulpar cavity
Connective tissue with vessels, nerves,
lymphatic vessels
What is a diphyodont
Has two sets of teeth (deciduous and permanent teeth)
What are deciduous teeth and which tooth types have deciduous teeth
aka “milk teeth” or primary teeth
Only I,C, and some P (no deciduous P1 and M)
What is a polyphyodont
Replace teeth regularly (ie a shark)
What is a monophyodont
one set of teeth (ie rodents)
Describe permanent teeth eruption
permanent tooth presses against the root of the deciduous tooth, causing gradual destruction of the deciduous root
The primordium of the permanent tooth is located on the lingual side
of the deciduous tooth
Name the dental formula for the maxillary arcade in the cat (deciduous and permanent)
i3 c1 p3
I3 C1 P3 M1
Name the dental formula for the mandibular arcade in the cat (deciduous and permanent)
i3 c1 p2
I3 C1 P2 M1
Name the dental formula for the maxillary arcade in the dog (deciduous and permanent)
i3 c1 p3
I3 C1 P4 M2
Name the dental formula for the mandibular arcade in the dog (deciduous and permanent)
i3 c1 p3
I3 C1 P4 M3
Name the dental formula for the maxillary arcade in the ruminant (deciduous and permanent)
i0 c0 p3
I0 C0 P3 M3
