A

-Coronal

19
Q

What directions does hyper-osmotic solutions cause the the fluid to move in the dentinal tubules?

A

-Coronal

20
Q

What is irreversible pulpitis?

A
  • If Symptomatic means the pain is intermittent or spontaneous
  • Pain stimulations is heightened and prolonged
  • If Asymptomatic means the caries possibly into pulp space (best time to treat)
21
Q

Do you see radiographic changes in irreversible pulpitis?

A

-Minimal or no radiographic changes

22
Q

T/F with irreversible pulpitis the pulp will eventually become necrotic

A

True

23
Q

Is RCT therapy needed for irreversible pulpitis?

A

Yes

24
Q

What is the only classification describing histological status of pulp or lack there of?

A

-Pulpal necrosis

25
Q

What is pulpal necrosis subsequent to?

A

-Irreversible pulpitis

26
Q

Following complete pulpal necrosis symptoms usually subside until when?

A

-The disease extends into PA tissues

27
Q

What type of response to the cold test do you get with Pulpal necrosis?

A

-No response

28
Q

What can heat do in pulpal necrosis?

A

-Sometimes exacerbates pain due to expansion of gases or fluids

29
Q

What are some endodontic diagnostic tests?

A
  • Percussion
  • Examination
  • Palpation
  • Thermal test
  • Electric pulp testers
30
Q

What are objective tests for endo?

A

- Ice

33
Q

What do you use for a heat test in endo?

A
  • Rubber prophy cup
  • Gutta Percha stick
  • Battery powered
34
Q

What is an electric conductor and how do you use it?

A
  • Test pulp vitality
  • Conductor use toothpaste
  • No gloves
  • Can only detect vital tissue
35
Q

Periapical lesions of endodontic origin, what do you see in a radiograph?

A
  • Lamina Dura lost apically (widened)
  • Lucency remains at apex despite angulation
  • Lucency resembles hanging drop
  • Tooth has necrotic pulp
36
Q

Where does bone loss have to extend to, to be observed in an necrotic tooth?

A

-Junction of cortical and cancellous bone

37
Q

T/F Bone loss in cancellous bone not detected

A

True

38
Q

Are anterior and pre-molar teeth apices or molar roots apices located closer to the cortical/cancellous junction?

A

What is a reaction to pulp or periapical inflammation that results in density of bone?

A

-Condensing Osteitis

40
Q

What occurs in an inflamed pulp with dentinoclastic activity?

A

-Internal resorption

41
Q

What is Calcific Metamorphosis?

A
  • Long-term low grade pulpal irritation
  • Dentin formation obliterates canals (usually a history of trauma)
  • Not always pathosis
42
Q

What are pulp stones?
