Q

Vital Pulpotomy objective is to

A

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

Q

Complete root canal

A

maintains tooth function but tooth is dead

mature tooth >24m

remove pulp, fill root canal, seal apex and lateral canals**

Q
A

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

Q

Tooth luxation

A

partially dislocated from alveolus but retains some attachment

26
Q

Tooth avulsion

A

completely displaced from alveolu

27
Q

Tooth luxation is a true____ if you want to save tooth

A

emergency

after 30mins success goes down exponentially

28
Q

Tooth luxation success depends on survival of ____

A

periodontal ligament

29
Q

Can we save this tooth?

A

NO -extract

30
Q

Tooth luxation- have the owner do what if possible?

A

push tooth back into the alveolus

31
Q

If tooth is avulsed, MUST keep tooth ____

A

moist

saliva, milk, saline

32
Q

Tooth luxation/avulsion. If tooth is dirty?

A

flush tooth with saline but DO NOT use antiseptics or scrape surface

33
Q

Reseat the tooth in alveolus and the _____

A

splint in place- around 4 weeks

34
Q

If tooth has reattached after splinting in place for 4 weeks, we can go ahead with ____

A

root canal

35
Q

Always follow up with ____

A

rads

36
Q

Tooth resoption synonyms

A

feline odontoclastic resoptive lesions (FORL)

neck lesions, cervical line lesions

canine odontoclastic resorptive lesions (CORL)

37
Q

T/F: tooth resorption lesions are caries

A

FALSE not cavities

38
Q

Tooth resorption etiology

A

unknow- vit D?

39
Q

Most common disease of tooth structure in domestic felines

A

tooth resorption

40
Q

stages of tooth resorption based on appearance

A
41
Q

Type 1 resorptive lesions

A

moderate to severe gingivitis and peridonitis frequently present

typicall associated with periodontal dz

classic “neck” lesions

42
Q

Type 2 resorption

A

no or minimal evidence of peridontitis

periodontal ligament- hard to identify or is gone, probably dead

typically extensive resorption of roots

43
Q

Type 3 resorption

A

multirooted teeth

features of type 1 and 2 in same tooth

44
Q

Clinical signs of resorptive lesions

A

pain: dropping food, chattering, anorexia, reluctance to have mouth examined

45
Q

How can we assess the full mouth involvement of resorptive lesions

A
46
Q

Treatment of resorptive lesions

A
47
Q

Type of lesion

describe

tx?

A

type 1 resorptive lesion

periodontitis present with horizontal bone loss

note fractured root tip on mesial root

complete extraction of tooth is indicated

48
Q

type of lesion?

describe

tx?

A

type 2 resorptive lesion

this would be a good candidate for crown amputation since there is no evidence of peridontal dz

49
Q

Gingivostomatitis

cause?

species/breeds?

signs?

A

unknown cause- calicivirus, bacterial, immunological

CATS: siamese, abyssinians, persians, himalayans, burmese

signs: pytalism, halitosis, dysphagia, anorexia, weight loss

50
Q

Gingivostomatitis

what teeth?

inflam of what?

A

severe marginal gingivitis

maxillary teeth caudal to canines most commonly affected

inflam: commisures, palatopharyngeal arches and caudally, palate

51
Q

Gingivostomatitis

dx

Ddx

A

Dx: histopathology, clinical appearance, typical hx

Ddx: neoplasia, autoimmune, eosinophilic granuloma syndrome

52
Q

Gingicostomatitis treatment

A

EXTRACTION is best

53
Q

Leaving any root tips in can cause persistence of lesions so- _____ are essential

A

post extraction rads

54
Q

Juvenile onset periodontitis

cause/breeds

signs

tx

A

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

55

This cat presented to emergency service with episodes of severe oral bleeding.

A

Eosinophilic granuloma

56
Q

Eosinophilic granuloma

skin lesions?

oral lesions?

A

skin lesions: ulcerations, linear granuloma

oral lesions: lip ulcer- rodent ulcer, hard palate erosion

ddx- oral SCC

57
Q

What artery do we need to be careful of in this area?

A

cups

kissing lesions

59
