Q

Type 2 tooth resorption

A

more common, body is effectively resorbing these (for some reason); asymptomatic, maybe some gingiva crawling on side of tooth

Q

which type of tooth resorption requires a crown amputation - type 1 or 2?

A

Type 2
take the exposed part and close the gingiva; tooth is eaten by odontoclasts while osteoblasts are filling in with new bone, so if you try to dig it out you’re gonna break their jaw

Q

pathogenesis of periodontal disease

A

plaque biofilm accumulate on the teeth and in the gingival sulcus –> gingivitis –> loss of bone height/soft tissue attachement –> plaque continues along newly exposed surface of tooth

this is a host-immune response to the plaque

Q

pathogenesis of feline oral SCC

A

SCC secretes cytokines that activate osteoclasts which destroy bone; also deposits keratin (inflammatory); can also occur sublingual/intralingual

Q

define

endodontic disease

A

PULP EXPOSURE and subsequent complications

26
Q

major complications of periodontal disease

A

oronasal fistulas and mandibular fractures

also obvi tooth movement, loss, deep pockets, etc.

27
Q

things needed on the dental record

A

oral findings, treatment provided, planned follow-up/future treatment, PICTURES!

do not memorize.
28
Q

number of permananet teeth in dogs

A

42

29
Q

number of permananet teeth in cats

A

30

30
Q

what tooth don’t cats have?

A

first premolar

also no lower P2

31
Q

define

apical

A

toward the apex/root tip

32
Q

define

coronal

A

toward the crown of the tooth

33
Q

define

mesial

A

side of tooth facing the center of the dental arch

34
Q

define

distal

A

side of tooth facing away from the center of the dental arch

35
Q

define

lingual/palatal

A

tongue side of tooth

lingual = mandibular; palatal = maxillary

36
Q

define

labial/buccal

A

outer surface of tooth facing lips/cheek

37
Q

3 Layers of Normal Dental Anatomy

A
  1. enamel
  2. dentin
  3. pulp
38
Q

define

enamel

A

hard calcified tissue that covers the dentin of the crown portion of the tooth

almost entirely made of mineral

39
Q

define

cementum

A

hard calcified tissue that covers the root of the tooth

40
Q

define

dentin

A

hard calcified tissue forming the middle layer of tooth

41
Q

define

pulp

A

cavity inside the root canal, pulp chamber that contains nerves, vessels, cells and fluid; purpose is to make more dentin

42
Q

apical delta

A

at the root apex where the pulp canal branches and forms tiny foramina

43
Q

Look at this diagram of a tooth.

A

smile, bitch

44
Q

Identify.

45
Q

4 Components of the Periodontum

A
  1. Gingiva
  2. Periodontal Ligament
  3. Cementum
  4. Alveolar Bone
46
Q

define

anodontia

A

complete absence of all teeth

very rare

47
Q

define

oligodontia

A

decreased number of teeth

common in dogs, uncommon in cats

48
Q

define

supernumerary teeth

A

it’s literally extra teeth.

49
Q

pesistent deciduous teeth are more common in what type of dog?

A

typically smaller dog breeds

50
Q

examples of tooth malformation

A
  • odontoma
  • dens invaginatus
  • gemination
51
Q

dens invaginitus

A

developmental malformation, typically bilateral, resulting in a tall crown with irregular infolded enaml and dental layers, convergent roots

52
Q

does every tooth with pulp exposure need extracted

A

yes
once pulp is exposed, it basically starts to die immediately and can migrate into surrounding tissues

53
Q

nasopharyngeal polyps

A

non-neoplastic soft tissue growths unique to cats which originate from the mucous membrane of the auditory tube or inner ear

54
Q

In how many locations should you bounce a probe around per tooth, minimum?

A

6

55
Q

define

gingival sulcus

A

the NORMAL gingiva surrounding a tooth

up to ~1mm deep in cats, up to ~3mm in dogs (size dependent)

56
Q

define

periodontal pocket

A

if the gingiva surrounding the tooth is PATHOLOGIC

57
Q

where do oronasal fistulas most commonly occur as a complication of periodontal disease in dogs?

A

the palatal aspect of the canine tooth

58
Q

oronasal fistula clinical signs

A

sniffing/snorting/sneezing, copius nasal discharge; mobile maxillary teeth, literally a hole

typically older small breed dog

59
Q

are discolored teeth dead?

A

probs - pulp “hemorrhages” leaks fluid into surrounding tissue/dentin –> stains. dead.

60
Q

Two Hallmarks of Endodontic Disease

A
  1. Periapical Lysis
  2. Pulp chamber stops narrowing
61
Q

how far coronally does the pulp chamber go in a cat canine tooth?

A

all the way to the cusp of the crown, so any cat with a broken canine probably has pulp exposure
