exam 1 - lecture 1 Flashcards
what type of teeth are equine teeth
hypsodont
amount of tooth eruption each year
2-3 mm/yr
how does eruption rate compare to attrition rate
similar, made to last 30 years
apical
away from occlusal surface
lingual surface
medial mandubular
palatal surface
medial maxillary
buccal
nearest cheek
mesial
front of mouth
interproximal space
space between teeth - should be tight
diastema
space between incisors and cheek teeth
curve of spee
angle of mandible
anisognathia
teeth dont meet up exactly, normal
maxilla wider than mandible
angle of occlusal surface
10-15 degrees
pre-molars in triadin
06-08
molars in triadin
09-11
which is the largest paranasal sinus
maxillary
the paranasal sinuses are
interrelated
MC cause of sinus dz in horses
dental dz
what teeth interact with rostral maxillary sinus
distal roots of 08 and all of 09
what teeth interact with caudal maxillary sinus
roots of 10 and 11
anatomy of maxillary cheek teeth
outer cementum, then enamel then infundibular enamel
which teeth have 5 pulp horns
all 07 to 10
which teeth have 6 pulp horns
all 06 and mandibular 11s
which teeth have 7-8 pulp horns
maxillary 11s
do mandibular cheek teeth have infundibulum
no
2 categories of enamel
peripheral and infundibular
3 types of enamel
1 - cheek teeth - wear resistance
2 - incisors - shear forces
3- less prominent, transitional
what is dentin for
tensile strength, compressibility
between enamel - form laminated structure
crack stoppers
what creates the irregular occlusal surface
dentin and cementum
types of primary dentin
intratubular and intertubular
types of secondary dentin
regular - continuous with primary
irregular - laid down from attrition of occlusal surface, prevents pulpar exposure
what is tertiary dentin
laid down locally in response to noxious stimuli
what is in pulp
connective tissue skeleton, vasculature, lymphatics, nerves
when do roots develop
by 2 yrs
which is the softest dental tissue
cementum
major structural component of clinical crown
cementum
what does cementum do
reparative function
deposited rapidly in response to stimuli
brachygnathism
short mandible
congenital
prognathism
protruding jaw
when do canines erupt
4-6 yrs
canine teeth are
brachydont
is it common to have mandibular wolf teeth
no
when do wolf teeth erupt
6-18 mo
how to remove wolf teeth
sedate, block, elevate, gently
how to age incisors
eruption times, shape, occlusal surface, glavaynes groove, dental stars
incisor eruption times
deciduous
01 - 6d
02 - 6 wk
03 - 6 mo
permanent
01 - 2.5 yr
02 - 3.5 yr
03 - 4.5 yr
cheek teeth eruption times
deciduous
06-08 - 2 wks
permanent
06 - 2.5 yr
07 - 3 yr
08 - 4 yr
09 - 1 yr
10 - 2 yr
11 - 3.5 yr
the growth of which tooth is mostly likely to cause issues
08 - grows in after 07 and 09
changes in shape for aging
<10 - wider than tall
10 - square
>10 - taller than wide
7/11 year hook
upper corner
not consistent
aging with dental cups
cups disappear and marks are oval, then smaller and rounder and move lingually
dental star
linear in young teeth
oval, then round with age
which is the only tooth structure after 18 years
dental star
when does the angle get more acute in the tooth
from 10 years
galvaynes groobe
upper corner incisors - 103/203
shallow groove on labial surface
all the way down at 20 years
