Endo Final - Avulsion

Front 1

When a mature tooth has a dry time of more than 60 minutes, it should be soaked in:
1. chlorhexidine
2. sodium hypochlorite
3. EDTA
4. fluoride/citric acid
5. calcium hydroxide

Back 1

4. fluoride/citric acid

Front 2

Which of the following events is inevitable following attachment damage to a root surface?
1. pulpal necrosis
2. irreversible pulpitis
3. increased tooth mobility
4. replacement resorption (ankylosis)
5. inflammation of the periodontal tissues

Back 2

5. inflammation of the periodontal tissues

Front 3

The optimal histologic consequence following avulsion is when the new PDL attaches:
1. directly to cementum
2. directly to reparative dentin
3. directly to enamel
4. directly to predentin
5. directly to primary dentin

Back 3

1. directly to cementum

Front 4

The follow-up schedule for the first year following an avulsed tooth is:
1. 1 month, 3 months, 6 months, 12 months
2. 1 month, 4 months, 8 months, 12 months
3. 1 month, 2 months, 4 months, 6 months, 12 months
4. 1 month, 3 months, 6 months, 9 months, 12 months
5. 1 month, 2, months, 3 months, 6 months, 12 months

Back 4

1. 1 month, 3 months, 6 months, 12 months

Front 5

A tooth replanted after excessive dry time leads to:
1. localized inflammation around the apical 1/3 of the root
2. localized inflammation around the middle 1/3 of the root
3. localized inflammation around the coronal 1/3 of the root
4. diffuse inflammation
5. increased risk of root fracture

Back 5

4. diffuse inflammation

Front 6

Checking for a more serious injury/medical condition following an avulsion should be done:
1. prior to replanting an avulsed tooth
2. at the same time as you replant the avulsed tooth
3. after you replant the avulsed tooth
4. by the patient’s physician within 1 week following replantation

Back 6

1. prior to replanting an avulsed tooth

Front 7

Attachment maintainance following tooth avulsion is achieved when the:
1. PDL cells are kept alive using appropriate measures
2. pulp is extirpated prior to replanting the tooth
3. root is rinsed under running water
4. root is cleaned thoroughly with saline soaked gauze
5. root is soaked in chlorhexidine

Back 7

1. PDL cells are kept alive using appropriate measures

Front 8

After a tooth is avulsed, which of the following steps is taken first at the dental office?
1. the avulsed tooth is replanted
2. a history of the dental trauma is obtained
3. the socket is inspected
4. an intra-oral soft tissue examination is carried out
5. the patient is sent for an anti-tetanus injection

Back 8

2. a history of the dental trauma is obtained

Front 9

In the dental office, what procedure is recommended regarding the socket prior to replantation:
1. remove the bood clot, visually inspect the socket and expose a radiograph
2. remove the blood clot, visually inspect the socket but do not expose a radiograph
3. expose a radiograph but do not remove the blood clot nor inspect the socket
4. curette the socket only
5. palpate the buccal sulcus only

Back 9

1. remove the bood clot, visually inspect the socket and expose a radiograph

Front 10

Which of the following is a complication of an avulsed tooth?
1. pressure resorption
2. ankylosis
3. periodontal disease
4. hyper-eruption
5. vertical root fracture

Back 10

2. ankylosis

Front 11

Which of the following does not consitute part of adjunctive emergency treatment protocol for a tooth that has been avulsed?
1. hydrocortisone tablets
2. systemic NSAIDS
3. chlorhexidine rinse
4. tetanus booster
5. anesthesia

Back 11

1. hydrocortisone tablets

Front 12

Attachment damage and pulpal inflammation leads to:
1. periodontal disease
2. root resorption and periodontal disease
3. apical periodontitis with root resorption
4. increased risk of root fracture
5. increased mobility in the long term

Back 12

3. apical periodontitis with root resorption

Front 13

Which of these findings are observed in all avulsion injuries?
1. attachment damage
2. pressure resorption
3. replacement resorption (ankylosis)
4. internal resorption
5. pulpal necrosis

Back 13

1. attachment damage
