Q

Where is bacteria often going to infiltrate the tooth and what is the pupal response?

A

Infiltrate at root apex, pulp will try to wall off

Q

What teeth are more likely to have accessory canals

A

Multirooted duh

17
Q

What is another common location for accessory canals

A

Furcation

18
Q

What is a common connection bw pulp and pdl that is not a canal

A

Dentin tubules

19
Q

How often does the CEj have a gap

A

10%

20
Q

Is it normal to have a perio lesion on one tooth

A

No its probably a pulpal lesion

21
Q

What is a problem associated with fraction accessory canals?

A

Bone loss

22
Q

How can a pulpal lesion affect perio

A

Primary endo lesion>accessory canal > perio effects

23
Q

How can you fix a perio problem with a pulpal origin?

A

Endo therapy

24
Q

What is crucial to resolving combined perio endo problems?

A

You must know the origin

25
Q

What are the ways pulp and perio lesions can be related

A
  1. Necrotic pulp extends to perio
  2. Pulpal lesion first, then perio
  3. Perio infection spreads to pulp
  4. Independent lesions coalesce
26
Q

What’s Treated first in a true combined lesion and why

A

Endo is first because success rates are more time sensitive.

27
Q

Does bone loss indicate a pulpal infection

A

No

28
Q

Why are perio effects on the pulp often only hypothesized?

A

Accessory canals are unlikely.

29
Q

What are the effects of perio infection of the pulp

A

Increased mineralization
Pulp narrows
Pulp stones

30
Q

Does severe bone loss lead to pulp disease

A

No

31
Q

What do studies say about the relationship between perio and pulp lesions?

A

No relationships confirmed

32
Q

What are three consequences of perio therapy that may affect the pulp?

A

Root exposure, cementum removal, dentin tubule exposed

33
Q

Will perio therapy affect pulp vitality

A

No but may have dentin hypersensitivity

34
Q

What are the symptoms of hypersensitivity

A

Sharp pain rapid onset

35
Q

What stimuli elicits dental pain

A

Hot cold sweet acid touch airflow

36
Q

How long does hypersensitivity last

A

One week, may be chronic

37
Q

How common is hypersensitivity

A

Uncommon

38
Q

What is a tooth generated cause of perio pockets?

A

Vertical fractures and perforations

39
Q

Will perio of an endo treated tooth respond differently to perio?

A

No
