A

Open

31
Q

A root fracture where on the tooth has the best prognosis?

A

Apical

32
Q

What is an injury to the tooth-supporting structures without abnormal lossening or displacement of the tooth (tooth will be tender to percussion and pressure because the PDL absorbed the force, but there is no sulcular bleeding or radiographic abnormalities)?

A

Concussion

33
Q

What is an injury to tooth-supporting structures with with abnormal lossening but without tooth displacement (can have sulcular bleeding and tooth will be mobile)?

A

Subluxation

34
Q

What is the difference between subluxation and concussion?

A

Mobility

35
Q

What would be the treatment, if indicated, beyond soft food for a subluxation of a permanent tooth?

A

Flexible splint no more than 2 weeks

36
Q

What is the term for the displacement of a tooth in a direction other than axially wherein the PDL is torn and contusion or fracture of the supporting alveolar bone occurs (crown is normally in a palatal or lingual direction. Will see an increased PDL space and displacement of the apex)?

A

Lateral luxation

37
Q

What is the treatment of permanent tooth lateral luxation?

A

Reposition and stabilize for weeks with flexible splint

38
Q

What risk is increased if a primary tooth that has been laterally luxated is repositioned by the dentist versus left to reposition on its own?

A

Necrosis

39
Q

What is the term for the apical displacement of a tooth into alveolar bone, compressing PDL and commonly causing a crushing fracture of alveolar socket?

A

Intrusion

40
Q

Will an intruded tooth be mobile?

A

No

41
Q

If the tooth is intruded with the crown palatally and the apex labial, how will the tooth appear radiographically?

A

Shorter

42
Q

Ift he tooth is intruded with the crown labially and the apex palatal, how will the tooth look radiographically?

A

Longer

Q

Which direction will a primary tooth most liekly intrude: labially or palatally?

A

Labially

44
Q

What treatment is indicated for all permanent teeth that have intruded and have complete root formation?

A

RCT within 3-4 weeks

45
Q

If you reposition an intruded tooth, what must be done for stabilization?

A

Splint for 2 weeks

46
Q

If there is more than 7mm of intrusion of a permanent tooth, what is required to reposition?

A

Surgery

47
Q

What is the term for a partial displacement of a tooth axially from the socket, a PDL torn, with the tooth looking elongated, mobile and increased PDL space apically?

A

A

RCT within 7-10 days

55
Q

What is the cut-off dry time for an avulsed tooth to consider a PDL necrotic?
