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

25
Tooth luxation
partially dislocated from alveolus but retains some attachment
26
Tooth avulsion
completely displaced from alveolu
27
Tooth luxation is a true\_\_\_\_ if you want to save tooth
emergency after 30mins success goes down exponentially
28
Tooth luxation success depends on survival of \_\_\_\_
periodontal ligament
29
Can we save this tooth?
NO -extract
30
Tooth luxation- have the owner do what if possible?
push tooth back into the alveolus
31
If tooth is avulsed, MUST keep tooth \_\_\_\_
moist saliva, **_milk_**, saline
32
Tooth luxation/avulsion. If tooth is dirty?
flush tooth with saline but DO NOT use antiseptics or scrape surface
33
Reseat the tooth in alveolus and the \_\_\_\_\_
splint in place- around 4 weeks
34
If tooth has reattached after splinting in place for 4 weeks, we can go ahead with \_\_\_\_
root canal
35
Always follow up with \_\_\_\_
rads
36
Tooth resoption synonyms
feline odontoclastic resoptive lesions (FORL) neck lesions, cervical line lesions canine odontoclastic resorptive lesions (CORL)
37
T/F: tooth resorption lesions are caries
FALSE not cavities
38
Tooth resorption etiology
unknow- vit D?
39
Most common disease of tooth structure in domestic felines
tooth resorption
40
stages of tooth resorption based on appearance
41
Type 1 resorptive lesions
moderate to severe gingivitis and peridonitis frequently present typicall associated with periodontal dz classic "neck" lesions
42
Type 2 resorption
no or minimal evidence of peridontitis periodontal ligament- hard to identify or is gone, probably dead typically extensive resorption of roots
43
Type 3 resorption
multirooted teeth features of type 1 and 2 in same tooth
44
Clinical signs of resorptive lesions
pain: dropping food, chattering, anorexia, reluctance to have mouth examined
45
How can we assess the full mouth involvement of resorptive lesions
46
Treatment of resorptive lesions
47
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
48
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
49
Gingivostomatitis cause? species/breeds? signs?
unknown cause- calicivirus, bacterial, immunological CATS: siamese, abyssinians, persians, himalayans, burmese signs: pytalism, halitosis, dysphagia, anorexia, weight loss
50
Gingivostomatitis what teeth? inflam of what?
severe marginal gingivitis maxillary teeth caudal to canines most commonly affected inflam: commisures, palatopharyngeal arches and caudally, palate
51
Gingivostomatitis dx Ddx
Dx: histopathology, clinical appearance, typical hx Ddx: neoplasia, autoimmune, eosinophilic granuloma syndrome
52
Gingicostomatitis treatment
**EXTRACTION** is best
53
Leaving any root tips in can cause persistence of lesions so- _____ are essential
post extraction rads
54
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
55
This cat presented to emergency service with episodes of severe oral bleeding.
Eosinophilic granuloma
56
Eosinophilic granuloma skin lesions? oral lesions?
skin lesions: ulcerations, linear granuloma oral lesions: lip ulcer- rodent ulcer, hard palate erosion ddx- oral SCC
57
What artery do we need to be careful of in this area?
Greater Palatine artery
58
What type of lesions?
cups kissing lesions
59
Dilaceration
curved root tip
60
Hypercementation
expansion of apical portion of root
