Maxillary sinus
Rostrally, which ones communicate? What about caudally?
Rostral: 08’s and 09’s communicate
Caudally: 10’s and 11’s communicate
Trigeminal nerve has what 3 branches?
- maxillary (sensory only)
- Mandibular (sensory and motor)
- Ophthalmic (sensory only)
Dental formula of foals/deciduous teeth:
3 0 3 / 3 0 3 = 12
Dental formula of adults/permanent teeth:
3 1 3 (4) 3 / 3 1 3 3 = 20(21)
01 incisors erupt when? What about 02’s incisors? And 03 incisors?
01 at 2.5 years
02 at 3.5 years
03 at 4.5 years
In wear occlusal surface features at __ years for middle, __ years for intermediate, and __ years for outer
3;4;5
cup gone at ages __-__
6-8 years of age
more of an angle means older or younger horse?
older
Birth to two years-
Incisor malocclusions (brachynathism –like Mac–or prognathism aka underbite)
Campylorrhinus lateralis esp. in arabians
Crowded deciduous incisors (blind wolf teeth)
what are the dental complications that may be seen in a horse that is 2-5 years:
Eruption problems (retained caps, impacted cheek teeth, eruption cysts or pseudocysts, canine tooth impaction) Several reports of complex odontomas in 2-4 year old horses
Odontoma is a begin tumor related to tooth development
5-20 years:
Infundibular caries
Occlusal deviations
Mandibular teeth do not have infundibula, but they can still develop “peripheral caries”
Rostral infundibulum of maxillary teeth incompletely filled with cementum–>predisposes to caries
Occlusal deviations (wave, sheer mouth, step)
My horse has occlusal deviations (a wave, step, sheer). what is the age range?
5-20 years old
over 20 years:
tooth displacement, overgrown teeth cracked/broken teeth, EOTRH
((EOTRH means Equine Odontoclastic Tooth Resorption and Hypercementosis))
horse needs floating when maxillary teeth are taller on ___ side and mandibular teeth are taller on ___ side
buccal; lingual
my horse has retained caps and some impacted cheek teeth, how old is he?
2-5 years
are pseudocysts normal?
Yes, eruption bumps of jaw remodeling and goes away with time, abn only if it creates a draining tract
___ ____ of maxillary teeth are incompletely filled with cementum which makes them predisposed to ____
Rostral infundibiulum; caries (cavities)
Mandibular teeth do not have _______ but they can still develop what??
infundibula; “peripheral caries”
Name this disease/ condition:
Rare disease seen in horses over 20 where you have lysis around canine roots, cementum lays down and you have to extract the tooth and cementum, very painful
EOTRH (Equine Odontoclastic Tooth Resorption and Hypercementosis)
