Equine dental radiography Flashcards
How do you prepare horses for dental radiography?
- usually heavy sedation required - detomidine and butorphanol
- head collar removed
What view is this? What is it used for?
Maxillary incisors: dorso-ventral view
- 101 to 103
- 201 to 203
- canine teeth 104 & 204
- roots of the teeth
- infundibulum
- density of bone
What view is this? What is it used for?
Mandibular incisors: ventro-dorsal view
- 301 to 303
- 401 to 403
What view is this? What is it used for? What is the downside?
Cheek teeth: latero-lateral view
Cheek teeth: latero-lateral view
Upper cheek teeth
Roots of 6 cheek teeth
Sinuses filled with gas
Downside - cheek teeth are superimposed
What view is this?
Cheek teeth: dorso-ventral view
Upper cheek teeth on the outside
Good for nasal septum in the centre of the picture
What view is this? Why is it helpful?
Maxillary cheek teeth: latero 30 degree dorsal-lateroventral oblique view
To highlight apex of cheek teeth on the other side to the generator
Can see individual cheek teeth
Right maxillary sinus
What view is this?
Mandibular cheek teeth: latero 45 degree ventral-laterodorsal oblique view
What view is this?
Temporomandibular joint: rostro 35 degree lateral 50 degree ventral-caudodorsal oblique
What condition is this?
Brachygnathia - parrot mouth
Mandible shorter than maxilla
What condition is this?
Polydontia
Too many teeth - 7 cheek teeth instead of 6
What condition is this?
Oligodontia - too few teeth
No molar to replace deciduous teeth
What condition is this?
Periapical abscess
* Widening of periodontal space
* Loss of lamina dura
* Periapical bone lysis
* Sclerosis of surrounding bone
* Destruction (blunting) of tooth apex
What condition is this image typical of?
Equine odontoclastic tooth resorption and hypercemetosis (EOTRH)
