pulp exposure

Question 1

treatment depends on

Answer 1

1) root development
2) size of exposure
3) time exposed
4) pdl injury

Question 2

in primary teeth

Answer 2

1) pulpotomy, pulpectomy, and extraction
2) no direct pulp caps

Question 3

small pulpal exposure on permanent teeth

Answer 3

1) small recent exposure
- direct pulp cap with MTA and GI and composite bandage
2) non recent exposure
- cvek pulpotomy for apexogenesis
- remove coronal pulp 1-3 mm until good hemostasis
- irrigate and MTA
3) non vital tooth
- pulpal regeneration or apexification
- RCT if root developed

Question 4

large pulpal exposure

Answer 4

1) recent on immature tooth
- Cvek on vital tooth
- pulpal regeneration or apexification on non vital
2) non recent and immature tooth
- pulpal regeneration or apexification
3) mature tooth
- RCT

Question 5

corwn root fracture

Answer 5

1) enamel, dentin, and cementum fracture with or without pulp exposure
2) oblique and vertical fracture are more difficult to manage

Question 6

crown root fracture on primary dentition

Answer 6

1) if unrestorable, extract it
2) only remove coronal fragment

Question 7

crown root fracture on permanent dentition

Answer 7

1) stabilize the coronal fragment
2) reduction, non rigid splint, soft diet
3) alternatives
- restoration
- rebonding it
- orthodontic extrusion
- surgical extrusion
- recoronation
- extraction
- Cvek, RCT, pulp capping for non vital

Question 8

root fracture

Answer 8

1) dentin and cementum fracture
- always involves the pulp
2) apical third fracture better prognosis

Question 9

root fracture on teeth treamtent

Answer 9

1) extraction of coronal fragment
1) permanent teeth
- reduce fracture
- non rigid splint
- RCT up until fracture line

Question 10

root fracture healing

Answer 10

1) hard > connective tissue > granulation tissue

Question 11

alveolar fracutre

Answer 11

1) incolves the whole alveolar bone
2) entire segment could be mobile
3) occlusal change

Question 12

alveolar fracture stabilization

Answer 12

1) primary
- manual repositioning, flexible splint
- general anesthesia
2) permanent
- manual repositioning or forceps
- stabilize

Question 13

bumped tooth

Answer 13

1) primary
- observation and soft diet
- symprtoms may not appear for a while
2) permanent
- pulpal necrosis risk is minimal but careful followup needed

Question 14

subluxation

Answer 14

f1) injury to tooth supporting structures without displacement
2) raadiographic abnormalities

Question 15

subluxation treatmetn

Answer 15

1) soft food and observation
2) similar to luxaiton
