Q

When treating a patient with a fracture injury what does the GDP do in the permanent stage?

A

If apexogenis has occurred (take radiographs) and the root is continuing to grow or the dentine wall is thickening, then this is the ideal situation.
Apexification - the tooth is no longer vital and the root of the tooth has not continued to grow. A man-made apex must be made in order for RCT to be carried out. This can be done with MTA. These teeth however have a poor prognosis as dentine walls are thin.
Root filling
Final coronal restoration

Q

When repositioning a tooth after trauma, what should you always do afterwards to check it has been repositioned correctly?

A

Take a radiograph

27
Q

Outline the stages of treatment for an apical and middle 1/3 root fracture.

A

Clean area with saline or chlorhexidine
Then reposition the tooth with digital pressure.
Place a flexible splint for 4 weeks
Stress the importance of OH compliance and a soft diet but not too soft that the PDL isn’t stimulated (as this can cause the tooth to heal poorly and become ankylosed to the bone)
Then review at 6-8w, 6m, and yearly for 5years with radiographs

28
Q

What is the difference between treatment for apical/middle and coronal root fractures?

A

The flexible may have to be worn for up to 4 months.

29
Q

What are the 4 different types of healing outcomes for RF?

A

Calcified tissue union across the fracture line
Connective tissue
Calcified + connective tissue
Bone/osseous healing

30
Q

Non-healing outcomes for RF?

A 
Granulation tissue (associated with loss of vitality)
Radiolucency is seen on radiograph around the fracture line
31
Q

What type of healing is desirable?

A

Calcified healing union across the fracture line

32
Q

What treatment is carried out if the RF tooth becomes non-vital?

A 
Extirpate the pulp to the fracture line and irrigate with SH.
Dress with CaOH 
Make a barrier with MTA or Biodentine.
Fill with GP
Restore tooth as normal
33
Q

How long do you splint these types of injuries?

  • Subluxation
  • Extrusion
  • Avulsion open and closed apex <60mins EADT
A

2 weeks

34
Q

What are the 7 types of PDL injuries classified as?

A 
Concussion 
Subluxation 
Extrusion 
Lateral luxation 
Intrusion 
Avulsion 
Dentoalveolar fractures
35
Q

What is a concussion trauma?

A

The tooth has been bumped slightly but there has been no damage to the PDL

36
Q

How would a concussion present and what would you do to treat it?

A

Present with some bleeding and numbness. May not pass sensibility tests
Would just suggest analgesia and then monitor

37
Q

What is a subluxation?

A

An injury to the tooth where the PDL has been damaged but the tooth hasn’t been displaced.

38
Q

What is an extrusive luxation?

A

The tooth has been displaced out of the socket and torn the PDL.

39
Q

What is a lateral luxation?

A

This is an injury to the PDL where PDL is crushed on one side and torn on the other, as the tooth moves in one direction.

40
Q

With PDL injuries do open apex or closed apex teeth have a better prognosis?

A

Open

41
Q

What are some possible reasons for PDL injuries?

A

Trauma due to contact sports or falling.

42
Q

How would you treat a lateral luxation injury?

A

Give LA
Reposition the tooth
Flexible splint for 4 weeks
Review radiographically and clinically ar 4we, 6-8w, 6m and yearly for 5y.
Checking for root resorption and radiolucencies

43
Q

What do you check for when following up with PDL trauma patients?

A

Checking for root resorption and radiolucencies

44
Q

Intrusion injury?

A

This is a crushing injury of the PDL as the tooth pushed up into bone.

45
Q

What is a common side effect of severe PDL injuries?

A

Root resorption

46
Q

What advice would you give for all luxation injuries in terms of OHI, daily life, and diet?

A

Instruct them to brush gently but keep the area clean with 0.1% chlorhexidine gluconate mouthwash ( or 0.2 CH).
Avoid contact sports
Have a soft diet but not too soft as need to stimulate PDL otherwise won’t heal properly. Suggest foods like bread.

47
Q

In open apex teeth, what are the 3 treatments for intruded teeth?

A

If it is less than 7mm then natural re-eruption but for more.
Rapid orthodontics or surgical repositioning (with forceps)

48
Q

For intrusion injuries of closed apex teeth. There is no need to slowly reposition the tooth to preserve vitality. Why is this?

A

Cause there is a 0% of pulpal survival. Therefore surgical reposition and RCT indicated.

49
Q

Treatment for intrusion?

A

Reposition depending on the root development.
Flexible splint of 4weeks (a temporary filling of CaOH recommended)
RCT (show be completed within 3-4weeks)

50
Q

Why is CaOH recommended for intrusion injuries?

A

Due to its;
Antimicrobial properties
Inhibits root resorption
Induces repair by hair tissue formation

51
Q

What does EADT mean?

A

Time tooth has been out the mouth and not been in a suitable storage medium

52
Q

What does EAT?

A

Total time tooth has been outside the mouth (including in a suitable storage medium)

53
Q

What are some examples of appropriate storage mediums?

A

Cold Milk
Saliva
Blood
Saline (physiological)

54
Q

If a teacher calls you in an emergency with a child that has an avulsed tooth, what advice would you give her?

A

Firstly if hold the tooth by the crown and not the root.
Clean any debris off the tooth under cold water for no more than 10 seconds then reimplant the tooth and get the child to bite down on some tissue.
If this isn’t possible then store in an appropriate medium such as cold milk, saline, or blood.
Then seek immediate dental advice.

55
Q

What the PDL healing outcomes for Avulsion.

A

Regeneration
PDL/cemental healing
Boney healing
Uncontrolled infection

56
Q

What the pulpal healing outcomes for Avulsion.

A

Regeneration
Controlled necrosis (RCT)
Uncontrolled necrosis

57
Q

What is the most important factor in the prognosis of avulsed teeth?

A

The EADT

58
Q

What is the treatment for an avulsed tooth of an EDT < 60mins?

A

Reposition the tooth under LA
Splint for 2 weeks
Consider tetanus shot and AB
Carry out RCT on the tooth as soon as possible unless it’s an open apex then there is a chance of revascualrisation.

59
Q

Talk through the stages of RCT for a closed apex avulsed tooth?

A

Tooth has been repositioned under LA
A splint has been placed for 2 weeks.
The pulp has been extirpated and disinfected (SH)and an AB steriod paste has been placed as an intracanal medicament.
At two weeks the AB steroid intracanal medicament is replaced by NSCaOH.
Then left for a further 2weeks when obturation with GP is carried out.
Review at 3m, 6m, and yearly for 5y and refer to pediatric specialists.

60
Q

What is the difference between EAT > 60 mins when compared to EAT< 60mins?

A

Splint for 4 weeks instead of 2

The prognosis of the tooth is a lot worse

61
Q

When would you not reimplant a tooth?

A

Almost never but
If a child is immunocompromised
If they had other serious injuries that needed more serious attention.

62
Q

If the tooth has an open apex and the EAT< 60mins so you decide to reimplant and splint (2w) without RCT. What must you look for at follow-up appointments and why?

A

Must look for pulpal necrosis as can cause inflammatory resorption.
In this case, the pulp must be RCT ASAP

63
Q

Treatment of a dentoalveolar fracture?

A

LA
Reposition (may have to lift up and over an apical block)
Then splint for 4 weeks
Prescribe AB
Review 4w, 6-8w, 4m, 6m, and yearly for 5y
