Q

Why does tooth crowding, rotationa nd or malocclusions predispose dogs to periodontal dz?

29
Q

What are the features of diets that can affect mouth health and periodontal dz (not seen that often)

A
  1. texture–dental diet vs reg
  2. pH–irritation at lower pH
  3. carbohydrates–increased sugars
  4. vitamins-decreased vit C, D, Se
  5. minerals-decreased Ca, P
30
Q

What are local irritants that and can cause periodontal dz?

A
  1. malocclusions, crowding, bruxism–indirect trauma–structural sress to roots and tissues of teeth–>PD or direct trauma
  2. foreign body –fibers–rope bones, socks, hair
31
Q

Why is home care important for PD?

A

within minutes of cleaning ther eis a thin pellicle or biofilm of salivary glycoprotein covers the tooth, within hours bacteria are incorporated–>plaque development

32
Q

What is the WCVM gold standard of home care?

A
  1. daily brushing–sulcular method, horizontal plane, 45 degree angle towards the tooth
    a.. soft bristle human
    b. replace brush once a month
    c. buccal/labial aspect (inside if possible esp weiner dogs)
    (NOT human toothpaste)
  2. oral hygiene rinse–antimicrobial
  3. oral hygiene gel-zinc, tuarine
  4. dental diet-mechanical
33
Q

What are clinical signs of periodontal disease?

A
  1. halitosis
  2. red, edematous, painful gingiva
  3. gingival bleeding while chewing or during probing
  4. plaque and calculus
  5. gingival recession
  6. tooth mobility
  7. dysphagia and dropping food
  8. abrnomal mastication pattern
  9. pawing at or rubbing mouth
  10. unwilling to play with toys
  11. ptyalism
  12. discharge from nasal and/or oral cavity
34
Q

What are the 4 stages of periodontal disease?

A
  1. stage 1: gingivitis only without loss of attachment (no attachement loss, reversible with home care, recheck)
  2. stage 2: early periodontitis (
35
Q

What is the treatment of stage 2 periodontal disease?

A
  1. oral hygiene/prophylaxis

2. periodontal surgery–root planing (subgingival scaling)/gingival curettage for PP

36
Q

What are the features of stage 3 periodontal disease?

A

moderate periodontitis
25-50% loss of periodontal attachment
F2
M2-3

37
Q

What is the treatment for stage 3 periodontal disease?

A
  1. oral hygiene, prophylaxis
  2. periodontal surgery (open rooth planing for PP >5mm, gingivectomy)
  3. recheck 2wk, 3mo
  4. home care (good to guarded px)
  5. extraction
38
Q

WHat are the features of stage 2 periodontal disease?

25-50% loss of perodontal attachment
F2
M2-3

40
Q

What are the treatments for grade 3 periodontal disease?

A

remove all the material below the gumline!!!
oral hygiene/prophylaxis
periodontal surgery–open rooth planing for PP >5mm
gingivectomy
recheck at 2wks nd 3 months
home care (good to guarded)
extraction–if owner not willing to maintain cleaning at home!

41
Q

What is stage 4 periodontal disease?

A

advanced periodontitis
>50% loss of periodontal attachment
F3
M3

42
Q

What is the treatment for stage 4 periodontal disease?

A
  1. oral hygiene/prophylaxis
  2. periodontal surgery (open rooth planing for PP >5mm)
    guided tissue regeneration
    gingivectomy
    recheck 2 wks and 3 months
    home care–guarded to poor prognosis
    extraction
43
Q

What are complications of perioodontal disease

A 
tooth loss
oral nasal/antral fistulal
perio-endo lesions
chronic ulcerative paradental stomatitis (CUPS)/lymphoytic plasmacytic stomatitis (LPS)
tooth resorptionn
44
Q

What is treatment for oral nasal fistulas?

A

extraction
single or double mucoperiosteal flap (debride scar tissue)
antibiotics

45
Q

How can periodontal disease lead to endodontic disease?

A

via access via lateral/accessory canals

via the apex

46
Q

How do you diagnse perio-endo lesions?

A

by x-ray

47
Q

How do you treat perio-endo lesions?

A

rooth canal and periodontal treatment

extraction

48
Q

What is CUPS/LPS?

A

severe ulceration often involving tissues CONTACTING TEETH
PAINFUL, can be cyclic
teeth may be relatively normal

49
Q

What is the etiology of CUPS/LPS

A

immune response

50
Q

What are clinical signs of CUPS/LPS

A

not eating, head shy, drooling, smells bad

51
Q

What is the treatment for CUPS/LPS?

A

extraction of teeth >PD2
meticulous home care! twice a day!
not being cured, it is long term treatment
antibiotics, pain control and glucocorticoids

52
Q

Why should all cats with CUPS/LPS be FIV, FeLV tested?

A

Not because changes treatment but may affect what client willing to pay. (are they predisposed?)

53
Q

How does tooth resorption occur?

A

Inflammation causes activation of odontoclasts = tooth destruction

54
Q

How prevalent is tooth resorption?

A

6/10 cats have evidence of tooth resorption

55
Q

What are the types of tooth resorption?

A

type 1 the peridodontal ligament is intact (dark line on x ray)
type 2 the periodontal ligament is not intact?

56
Q

How do you diagnose tooth resporption?

A

exam and x rays

57
Q

What is treatment of tooth resorption?

A

extraction! even if a small lesion. painful if above the gum line
crown amputation and intentional rooth retention–can do crown amputation only if it is type 2 and there is no intact periodontal ligament–cannot see where tooth rooth ends and bone begins. That is not appropriate for type 1. Then you would do a gum flap
don’t seem to be painful below the gumline
