Q

How do we carry out a partial pulpotomy

A
  1. LA and isolation
  2. Removal 2mm pulpal tissue
  3. Haemostasis
  4. Apply non setting calcium hydroxide
  5. Apply hard setting linign
  6. Restore
17
Q

What is another term for partial pulpotomy

A

Cvek pulpotomy

18
Q

What I the success rate of partial pulpotomies

19
Q

When would we opt to carry out a cervical pulpotomies

A
  1. Immature teeth

2. Necrotic/ contaminated tooth

20
Q

What is the success rate fro cervical pulpotomies

21
Q

If you have a necrotic pulp with a closed apex two would you treat it

A

Pulpectomy

22
Q

If you have a necrotic pulp with an open apex two would you treat it

A

Apexification

23
Q

What is Apexification

A

A method of inducing apical closure through the formation of mineralised tissue in the apical pulp region of a non vital tooth with an open apex

24
Q

What are the problem with Apexification

A
  1. There is no increase in root dimensions
  2. Final root filling is difficult
  3. Root predisposed to fracture
25
How do we carry out Apexification
1. Establish working length (1-2mm short of apex) 2. Chemo mechanical preparation with large files 3. Sodium hypoclorite irrigation 4. Dress with calcium hydroxide 5. Reassess and redres 3 monthly 6. obturate definitely when hard apical barrier formed
26
What is the prognosis for Apexification
1. 75%-96% form a hard tissue apical barrier | 2. Hard risk of cervical root fracture
27
What are some alternative treatments to Apexification
1. Premolar transplant 2. MTA (Mineral Trioxide Apatite) 3. Regenerative Endodontic Therapy
28
How common are crown root fractures
0.5% of all traumatic injuries
29
Where can the fracture line extend to in a crown root fracture
1. Below the gingival crevice | 2. Below alveolar bone margin
30
What problems can we encounter when restoring a crown root fracture
1. Isolation | 2. Margins
31
What are the treatment options for a crown root fractures
1. Supragingival restoration 2. Surgical exposure of fracture site 3. Surgical extrusion 4. Orthodontic extrusion
32
How do we classify root fractures
1. Horizontal or vertical | 2. Single or multiple
33
How can we diagnose a root fracture
1. Increased mobility seen 2. Extrusion or lateral luxation of crown seen 3. Visible on a radiographie taken in 2 angle s
34
How do we treat a stable undisplaced root fracture
Do not splint just monitor
35
How do we treat a root fracture that has led to pulp necrosis
Root fill to fracture line
