Q

Is calcium hydroxide (Dycal) antibacterial or bacteriostatic, and how does it work?

A
  1. Antibacterial

2. Disinfects superficial pulp due to alkalinity

20
Q

What does calcium hydroxide do to deeper portions of the pulp?

A

Mild irritant to deeper portions of pulp, initiating inflammatory response

21
Q

What occurs when calcium hydroxide is placed and bacteria are not present?

A

Healing with a hard tissue barrier

22
Q

Mineral trioxide aggregate (MTA) has what pH and dissociates into what compound?

A
  1. Alkaline pH2. Dissociates into Ca(OH)2
23
Q

What is a major difference between MTA and Ca(OH)2 as far as placement?

A

MTA requires moisture to cure

24
Q

MTA is considered better than Ca(OH)2 for what reason?

A

Seems to induce continued root wall thickness

25
Q

Torabinejad states what difference between MTA and Ca(OH)2 as far as tissue response?

A

Tissue response to MTA is excellent, whereas there is always a zone of necrosis beneath Ca(OH)2

26
Q

What are the indications to choose partial pulpotomy vital pulp therapy for a complicated crown fracture?

A
  1. Immature tooth with large exposure

2. Longer exposure period (more than 24 hours)

27
Q

For a partial pulpotomy to be indicated on a complicated crown fracture, how far down can the zone of inflammation of the exposed vital pulp extend?

A

Zone of inflammation extended more than 2mm apically but not to the level of the root pulp

28
Q

Partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy goal is to remove tissue down to what and where may this occur in the tooth?

A

Down to the normal pulp. May occur at orifice or below orifice.

29
Q

What is the success rate of a partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy mainting pulp vitality with continued root development (i.e. growth in length of root and increased root wall width)?

A

94-96%

30
Q

When doing the partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy to what level is the pulp amputated?

A

2mm below exposure site or to fresh bleeding

31
Q

Dr Replogle says to use what type of bur to do the partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy?

A

Sterile diamond bur

32
Q

Partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy should be irrigated with what solutions?

A

Saline or chlorhexidine

33
Q

What restoration covers a partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy?

A

Ca(OH)2 or MTA covered by a bonded restoration

34
Q

Torabinejad says hemostasis should be expected within how many minutes of exposing new pulp during a partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy?

A

5 minutes

35
Q

What should be created surrounding the pulp wound in a partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy?

A

Dentin shelf

36
Q

Torabinejad says what should be palced over the Ca(OH)2 or the MTA in a partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy?

A

Glass ionomer, then restore with acid etched composite

37
Q

If Ca(OH)2 is placed during a partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy, what does Torabinejad state should be done after a time of 6-12 months?

A

Reenter and remove Ca(OH)2 and replaced with a dentin-bonding material to prevent microleakage onto the new dentin bridge that has formed as Ca(OH)2 has broken down

38
Q

If MTA is used during a partial pulpotomy / cervical pulpotomy / shallow pulpotomy / Cvek pulpotomy, is reentry after 6-12 months required?

A

No

39
Q

What are the materials for vital pulp therapy?

A
  1. Ca(OH)2/Dycal
  2. MTA
  3. Vitrebond
40
Q

What is a vital pulp therapy material that is hard setting and has a pH of 12 that stimulates odontoblastic activty?

A

Dycal (calcium hydroxide)

41
Q

What is a vital pulp therapy material that is a cement with a pH 12 that stimulates odontoblastic activity?

A

Mineral trioxide aggregate (MTA)

42
Q

What is a vital pulp therapy material that is a glass ionomer that releases fluoride?

A

Vitrebond

43
Q

What is indicated with a complicated crown fracture whose apex is closed?

A

Pulpectomy

44
Q

If #30 on an 11 year old has a large carious lesion, and the child only has slight sensitivity to percussion and cold with no lingering pain whose pulp is exposed during caries excavation, but blood is normal and controlled within 5 minutes, what is the pulp and apex diagnosis and the indicated treatment?

A

Reversible pulpitis with normal apex

Treatment: Pulpotomy

45
Q

If #30 on an 11 year old has a large carious lesion, and the child only has slight sensitivity to percussion and cold with no lingering pain whose pulp is exposed during caries excavation, the blood was dark and not controllable, what is the pulp and apex diagnosis and the indicated treatment?

A

Irreversible pulpitis with symptomatic apical periodontitis

Treatment: NSRCT
