Answer 4

- Retained Deciduous teeth - Malocclusions - Supernumerary teeth - Trauma - Caries - Tooth Resorption (EOTRH syndrome)

Answer 5

maleruption of teh permanent tooth failure of root resoprtion

Answer 6

offset bite parrot mouth - surgery sow mouth

Answer 7

- Similar developmental abnormalities to cheek teeth can arise in incisors - Before too extraction take x – ray of this area. - Can have longer root than normal

Answer 8

- Common in young horses - Kicking injury, chew something - Doral ventral view: is much more informative for us: Where is the fracture line. - Cerclage wire fixation: Sedation (Xylazine, detomedine and sometimes with diazepam or butorphanol) - Fixation: Cerclage wire, Cerclage wire holders + holder, 3.2, or 2.5 gage drill guide or drill holder

Answer 9

develop due to fracture, kicking or hypocementosis

Answer 10

presents from normal through fractures or diseases teeth incisors and canines treatment - extraction causes pain and enlarged roots enlarged bulbs on root area

Answer 11

1st premolar remove in younger horses root can be x3 longer than crown area

Answer 12

- Overgrowth (Not only on 6th and 11th but also on the 9th and 10 too) - Supernumerary teeth - Diastema - Fracture - Infundibular caries - Pulpitis - Periapical infection - Displaced.

Answer 13

space btw teeth it can occur If there is a dispaement on the 9th and the angulation will change and diastema can built inbetween in a younger horse a older horse where the roots angulation change a bit more straight, not so angulated – diastema can occur quite easily there.

Answer 14

open and closed

Answer 15

Better prognosis ..> Can do the tooth rasping and cleaning this will heal.

Answer 16

The crowns in between there is a contact and under it there is a space where the food can accumulate and cause periodontal disease and cause infection in the periodontal ligament. can cause osteomyelitis and loosing of the 9th and the 10th tooth.

Answer 19

easier to detect in young horses mandibular - enlarged and painful can cause sinusitis and fistule canal formation maxillary - purulent nasal dishcarge from sinus. CT necessary

Answer 20

congenital - Difficulties during eruption. - Displacements caused by bad eruption or difficulties around eruptation. - MIB: Minimally invasive buccotomy (inbetween the infected tooth)

Answer 21

squamous cell carcinoma

Answer 22

rare strep infection ct needed

Answer 23

often tooth problem fracture, neoplasia, hematoma, sinus cyst

Answer 24

* Nasal discharge (Serous/mucopurulent) * Swelling/deformation * Decreased airflow (Dyspnoea, apnoea) * Sometimes see: Cutan fistula, Ocular Discharge or Fetid odor.

Answer 25

endoscope - medial meatus clinical exam of mouth sinoscopy ct/ scintography/ mri xray - radiodensity in sinus

Answer 26

1. removed periosteum from bone 2. drill 23mm hole into sinus frontalis 3. blindly take out bulla 4. can remove infected pus 5. create new exit from sinus into nasal passage (forceps) 6. folie catheter - lavage for 3-5 days 7. suture periosteum 8. sulture cutis and subcutis together

Answer 27

a lot of bleeidng

Answer 28

unknown aetiology symtpoms - swelling, decreased airflow, nasal discharge, stridor treatment - trepination

Answer 29

swelling, odour, nasal discharge, stridor
