E2- Dental dz 2 Flashcards
gingival hyperplasia
peripheral otodentic fibroma- benign
melanoma, fibrosarcoma, SCC
Name abnormality
pulpitis
focal spot in a younger dog- dentil tubules
name abnormality?
pulpitis
discolored teeth in older dog is most likely death
Whats in the circle?
dentinal tubules
T/F: pulpitis is often reversible
False- not often <10%
T/F pulpitis- the older the animal, the less likely the pulp is to survive
true
treatment of pulpitis
monitor
root canal
extraction
A- pulpitis: periapical lucency root resorption
B- normal tooth: chevron sign
Name lesion
Enamel infraction (abraction)
cracks in enamel, no loss of structure
Enamel fracture
loss of enamel only
Uncomplicated crown fracture
pulp chamber not exposed
Complicated crown fracture
pulp exposed
Uncomplicated crown/root fracture
pulp not exposed
Compliacted crown/root fracture
pulp exposed
Root fractured so we need to?
extract
Untreated complicated crown fractures are painful and will ultimately cause ____
periapical dz
Endodontic indication
fractured teeth
pulpitis
tooth luxation/avulsion
crown reduction- disarming, base narrow canines, soft tissue trauma after resections
certain types of dental caries
Advantages of endodontics
less invasive than extraction
preserves tooth function and integrity of jaw
more fun to do than extractions
Disadvantages of endodontics
expensive
longer anesthetic time
special instruments and training
Vital Pulpotomy objective is to
maintain a viable tooth that will continue to mature
the pulp is necessary to maintain dentin- w/o viable pulp, the tooth will become dehydrated and more brittle over time
Vital pulpotomy can be done in
young animals <18-24m
sooner the better
>80% initial success rate when <48hrs
Vital pulpotomy best success when?
planned procedure
monitor at least yearly- twice yearly better
Complete root canal
maintains tooth function but tooth is dead
mature tooth >24m
remove pulp, fill root canal, seal apex and lateral canals**
apical delta
lateral canal
complete filling of root canal seals apical delta and lateral canals preventing contamination in dentinal tubules from escaping from the tooth and causing inflam/destruction of the tooth supporting structures
Tooth luxation
partially dislocated from alveolus but retains some attachment
Tooth avulsion
completely displaced from alveolu
Tooth luxation is a true____ if you want to save tooth
emergency
after 30mins success goes down exponentially
Tooth luxation success depends on survival of ____
periodontal ligament
Can we save this tooth?
NO -extract
Tooth luxation- have the owner do what if possible?
push tooth back into the alveolus
If tooth is avulsed, MUST keep tooth ____
moist
saliva, milk, saline
Tooth luxation/avulsion. If tooth is dirty?
flush tooth with saline but DO NOT use antiseptics or scrape surface
Reseat the tooth in alveolus and the _____
splint in place- around 4 weeks
If tooth has reattached after splinting in place for 4 weeks, we can go ahead with ____
root canal
Always follow up with ____
rads
Tooth resoption synonyms
feline odontoclastic resoptive lesions (FORL)
neck lesions, cervical line lesions
canine odontoclastic resorptive lesions (CORL)
T/F: tooth resorption lesions are caries
FALSE not cavities
Tooth resorption etiology
unknow- vit D?
Most common disease of tooth structure in domestic felines
tooth resorption
stages of tooth resorption based on appearance
Type 1 resorptive lesions
moderate to severe gingivitis and peridonitis frequently present
typicall associated with periodontal dz
classic “neck” lesions
Type 2 resorption
no or minimal evidence of peridontitis
periodontal ligament- hard to identify or is gone, probably dead
typically extensive resorption of roots
Type 3 resorption
multirooted teeth
features of type 1 and 2 in same tooth
Clinical signs of resorptive lesions
pain: dropping food, chattering, anorexia, reluctance to have mouth examined
How can we assess the full mouth involvement of resorptive lesions
Treatment of resorptive lesions
Type of lesion
describe
tx?
type 1 resorptive lesion
periodontitis present with horizontal bone loss
note fractured root tip on mesial root
complete extraction of tooth is indicated
type of lesion?
describe
tx?
type 2 resorptive lesion
this would be a good candidate for crown amputation since there is no evidence of peridontal dz
Gingivostomatitis
cause?
species/breeds?
signs?
unknown cause- calicivirus, bacterial, immunological
CATS: siamese, abyssinians, persians, himalayans, burmese
signs: pytalism, halitosis, dysphagia, anorexia, weight loss
Gingivostomatitis
what teeth?
inflam of what?
severe marginal gingivitis
maxillary teeth caudal to canines most commonly affected
inflam: commisures, palatopharyngeal arches and caudally, palate
Gingivostomatitis
dx
Ddx
Dx: histopathology, clinical appearance, typical hx
Ddx: neoplasia, autoimmune, eosinophilic granuloma syndrome
Gingicostomatitis treatment
EXTRACTION is best
Leaving any root tips in can cause persistence of lesions so- _____ are essential
post extraction rads
Juvenile onset periodontitis
cause/breeds
signs
tx
unknown but starts early
siamese, maine coon, DSH
signs: severe gingivitis, periodontal dz
Tx: frequent prophylaxis, aggressive home care, some will outgrow it if can get to 2 years, extractions
This cat presented to emergency service with episodes of severe oral bleeding.
Eosinophilic granuloma
Eosinophilic granuloma
skin lesions?
oral lesions?
skin lesions: ulcerations, linear granuloma
oral lesions: lip ulcer- rodent ulcer, hard palate erosion
ddx- oral SCC
What artery do we need to be careful of in this area?
Greater Palatine artery
What type of lesions?
cups
kissing lesions
Dilaceration
curved root tip
Hypercementation
expansion of apical portion of root
