Q

How do you determine if there is an endodontic exposure ?

A

Probe with an explorer- if it enters the chamber, extract or do a root canal.

Reparative tertiary dentin is brown and hard.

Q

In which breed is gingival hyperplasia typically seen?

A

BOXER and Great Dane

Generalized gingival hyperplasia

17
Q

Which 3 drugs can cause gingival hyperplasia?

A

Cyclosporine
Calcium Channel blockers
Anticonvulsants

18
Q

What is the treatment of gingival hyperplasia ?

A

Remove excessive tissue to return sulcus depth to normal scalloped contour

19
Q

What sx procedure would you use for Gingivectomy ?

A

Radiosurgery
Electrosurgery
Co2 Laser
Fluted burr

20
Q

What is the clinical sign of Pulpitis?

A

Discoloration of the teeth

It may be reversible but NOT often. the older the patient the less likely, the pulp will survive.

21
Q

How would you treat pulpitis ?

A

Monitor –> Root canal or Extract

22
Q

What are the six classifications of tooth fracture?

A
  1. Enamel infraction (Abraction )
    - cracks in the enamel and no loss of structure
  2. Enamel fracture
    - loss of enamel only
  3. Uncomplicated crown fracture
    - pulp chamber is not exposed
  4. complicated crown fracture - pulp is exposed
  5. uncomplicated crown/root fracture
    - crown is NOt exposed
  6. Root fracture - extract
23
Q

What is the treatment for uncomplicated/enamel fractures?

A

Indirect pulp capping or crown restoration

24
Q

What is the treatment for complicated fractures?

A 
Vital pulpotomy (option in very young animals) or root canal 
Crown restoration or extraction of tooth
25
Q

What is the apical root resorption and apical lucency indicative of?

A

Associated with an endodontic disease and peri-apical inflammation

26
Q

What are the advantages of endodontics?

A

It is less invasive than extraction.

- Preserves tooth function and integrity of the jaw

27
Q

What are the disadvantages of endodontics

A
  • expensive
  • specialized skill - techinique sensitive
  • longer anesthetic time
28
Q

What is the objective of a vital pulpotomy?

A

It is to maintain a viable tooth that will continue to mature
- the pulp is necessary to maintain dentin

29
Q

What type of teeth can you perform a vital pulpotomy on?

A

Immature tooth
Very wide pulp cavity
Apex is not closed completely

30
Q

When does the apex close?

A

18-24 months

31
Q

Vital pulpotomy is >80% successful (initial) when

A

TRUTH

32
Q

What would you place on the exposed pulp?

A

ProRoot MTA or Calcium Hydroxide powder

33
Q

How ‘old’ should the mature tooth be for a complete root canal to be successful?

A

> 24 months

34
Q

What are the goals of a complete root canal

A

complete removal of pulp contents and sealing the apex to prevent bacteria from escaping from the tooth

35
Q

What must you always do when you have a retrobulbar dz ?

A

RADIOGRAPHS!

36
Q

Differentiate tooth luxation from tooth avulsion

A

Luxation - partially dislocated from alveolus but it retains some attachement

Avulsion is when it is completely displaced from the alveolus

37
Q

For a tooth luxation/avulsion, what is the time frame you have before the success of saving the tooth goes down exponentially?

A

30 minutes

38
Q

If the tooth is avulsed, you MUST keep the TOOTH MOIST - saliva, milk and saline

A

TRUTH
