Question 1

treatment aimed at preserving and maintaining pulp tissue that has been compromised by trauma, caries or restorative procedures in a healthy state

Answer 1

vital pulp therapy

Question 2

procedure in which a material is placed on a thin partition of remaining carious dentin that, if removed, might expose the pulp in immature permanent teeth

Answer 2

indirect pulp cap

Question 3

this is essential to eliminate infected tissues and visualize pulp tissue conditions under magnification when pulpal exposures occur

Answer 3

complete caries removal

Question 4

an opening in dentin that uncovers pulp

Answer 4

pulp exposure

Question 5

a pulp exposure resulting from the progressive destruction of tooth structure by acids and proteolytic enzyme elaborated through microbial activity ; underlying pulp is inflamed to a varying and unknown extend, due to the progression of dental caries

Answer 5

carious pulp exposure

Question 6

accidental exposure of the pulp by hand- or engine- driven dental instruments in the absence of dental caries; if aseptic conditions are maintained, the underlying pulp is usually not inflamed

Answer 6

mechanical pulp exposure

Question 7

pulp exposure due to a fracture of the tooth

Answer 7

traumatic pulp exposure

Question 8

pulp cap is treatment of exposed pulp by sealing the pulpal wound with a dental material such as _____ or _____ to facilitate the formation of reparative dentin and maintenance of a vital pulp

Answer 8

calcium hydroxide or mineral trioxide

Question 9

dental material placed directly on a mechanical or traumatic vital pulp expodure

Answer 9

direct pulp cap

Question 10

procedure in which a material is placed on a thin partition or remaining carious dentin that, if removed, might expose the pulp in immature permanent teeth

Answer 10

indirect pulp cap

Question 11

at UMKC, if a pulp exposure on a vital pulp may occur please follow this protocol:

Answer 11

1. isolate the tooth in question
2. remove all the remaining caries
3. irrigate with 8.3% NaOCl to achieve homeostasis
4. gently place DYCAL IN THE PULP EXPOSURE and a temp restoration
   5.

Question 12

removal of coronal portion of a vital pulp as a means of preserving the vitality of the remaining radicular portion; may be preformed as emergency procedure for temporary relief of symptoms or terapeutic measure, as in the instance of a Cvek pulpotomy (trauma)

Answer 12

pulpotomy (pulp amputation)

Question 13

removal of a small portion of the vital coronal pulp as a means of preserving the remaining coronal and radicular pulp tissues

Answer 13

partial pulpotomy(shallow pulpotomy; Cvek pulpotomy)

Question 14

teeth with deep carious lesions approaching the pulp and with signs of reversible pulpitis can be treated successfully by indirect pulp capping using either _____or _____

Answer 14

biodentine or Fuji IX

Question 15

when should direct pulp capping be preformed

Answer 15

only if the surrounding dentine is sound and the exposed pulp does not exhibit suggestive signs of infection.

Question 16

direct pulp cap with MTA method (Mineral trioxide aggregate)

Answer 16

1. deliver MTA with amalgam carrier or MTA carrier instrument (dentsply);
   DONT USE PLUGGER
2. blot excess moisture from MTA with dry cotton ball/forcepts; carve MTA 1.0mm past exposure site
3. restore

Question 17

has involved large part of the pulp chamber. tissue at RTC orifice is uninflamed with intact odontoblast layers

Answer 17

necrosis/infection

Question 18

outcome of partial pulpotomy in cariously exposed posterior permanent teeth has a success rate of

Answer 18

98%

(complete pulpotomy and direct pulp capping were associated with lower success rates)
