Surgical extraction of teeth

Question 1

luxator

Answer 1

thinner working end

sharper blade

Question 2

elavator

Answer 2

more rounded end

blade slightly more spoon shaped

Question 3

cutting gingival attachment

Answer 3

use scalpel

move v.slowly

Question 4

inserting luxator into periodontal ligament

Answer 4

move luxator down to the periodontal space
walk luxator around tooth - cut periodontal ligament + widen the gap
avoid holding instrument parallel to tooth - can slip onto alveolar bone

Question 5

what to use to widen gap between tooth + gum

Answer 5

elavtor placed down at base of tooth

rotate at several points then move deeper

Question 6

extraction

Answer 6

use extraction forceps

rotate and pull when at max point of rotation

Question 7

extracting a tooth with 2 roots

Answer 7

transect the tooth at the furcation

make sure both sections move independant then remove

Question 8

possible complications of extractions

Answer 8

root fragmentation
jaw bone necrosis
iatrogenic jaw fracture
oro-nasal fistula

Question 9

envelope flap

Answer 9

no vertical release incision

for feline tooth resorption

Question 10

vertical release incisions

Answer 10

1 incision for small tooth
2 incsions + oarger for larger tooth
2 incisions should be divergent

Question 11

be aware not to cut into these

Answer 11

The neurovascular bundle in infraorbital foramen
neurovascular bundle exiting from the mental foramen - Avoid during vertical release incisions for mandibular premolar extractions

Question 12

Tooth Resorption In Cats

Answer 12

One of the most common dental disease problems in cats
At least a third of adult cats have one or more lesions
Prevalence increases with age

Question 13

pathogenesis of tooth resorption

Answer 13

Teeth attacked by Odontoclasts (similar to osteoclasts)
Odontoclasts adhere to surface of the root and form resorptive lacunae
Vascular granulation tissue fills lesion + may be replaced by bone-and cementum-like tissue

Question 14

tooth resorption - treatment

Answer 14

Extraction = Currently the only accepted option
restorations have been done - unsuccessful
Medical therapy

Question 15

tooth resorption in dogs

Answer 15

Often coincidental findings during dental radiography
extract if supra-gingival/communication of lesion with oral cavity
Leave in if only subgingival + no sign of pain/radiographic sign of inflammation

Question 16

surgical extractions - step-by-step

Answer 16

plan flap
cut gingival attachment
perform release incisions - down to blood
lift flap - with elevator
Reflecting the flap to expose buccal jaw bone - gently
remove buccal alveolar bone plate - expose root
cut deeper grooves along the mesial and distal root outlines - not too deep - nasal cavity
put elevator/luxator in remaining peridontal ligament + rotate
remove with forceps
inspect root apex - check for fracture
smooth down bony spikes
close flap
