25
What does the prognosis of pulp therapy depend on?
- Associated PDL injury - Extent of exposed dentine - Age of pt (open or closed apex) - Time since injury
26
Indications fo Cvek pulpotomy
Traumatic pulp exposure of immature permanent teeth
27
Method of Cvek pulpotomy
- access through exposed surface - Remove 2-3mm of pulp tissue with high speed - Arrest haemorrhage - Irrigate - Dress pulp (NS CAOH or MTA) - Restore
28
Define apexification
Inducing a calcified barrier in a non-vital immature tooth (open apices)
29
Indications for apexification
Non-vital tooth with open apices
30
How long can the calcific barrier take to form in apexification
up to 9 months
31
Management of pulp exposure of a mature permanent incisor
Direct pulp cap Pulpotomy Pulpectomy Conventional RCT
32
Management of an avulsed mature permanent tooth
ALWAYS REQUIRES RCT as the apex is closed
33
Why are splints placed labially
- Prevents occlusal interference | - Allows access palatally for endo
34
How is an avulsed mature permanent incisor retained
Due to ankylosis
35
Emergency management of avulsed tooth that was replanted
- Leave in place - Clean with water, saline or chx - Suture gingival lacerations - RG to confirm position - Splint for 2 weeks - AB + tetanus - Post op instructions - Recall
36
Management for delayed replantation
Remove attached non-viable soft tissue with gauze RCT prior to replantation Fluoride application on the root
37
Why apply fluoride to the root in delayed replantation
Can slow down osseous replacement of the tooth
38
What is the aim of delayed replantation
Maintain alveolar bone height
39
Why has delayed replantation have a poor prognosis
All PDL cells are non-viable after >60 mins dry time
40
Difference between replanting immature and mature permanent teeth
All mature teeth will require rct whereas immature have the ability to revascularise
41
What is the aim of replanting an immature permanent tooth?
Maintain pulp vitality and allow continued root development
42
Contraindications for replantation
- Extensive caries - Perio disease - Non-cooperative pt - Severe cardiac conditions
43
Tx of enamel fracture
Smooth sharp corners | If extensive, composite restoration for aesthetics
44
Tx of ED fracture
GIC bandage Consider indirect pulp cap Restore definitively Monitor pulp vitality
45
Signs of ED fracture
Loss of tooth structure but no pulp exposure Pulp testing positive Not TTP or mobile
46
Signs of EDP fracture
Loss of tooth structure with exposed pulp Sensitivity to stimuli Not TTP or mobile
47
Tx of EDP fracture of an immature tooth
Immature - pulp cap or pulpotomy to preserve vitality
48
Tx of EDP fracture of mature tooth
RCT preferred | Can do pulp cap or pulpotomy
49
Signs of crown-root fracture
Fracture of enamel, dentine and cementum and extends below gingival margin - TTP - coronal fragment mobile - Gingival bleeding - Vitality testing positive for apical fragment
50
Emergency tx of crown root fracture
Stabilise with a splint | If pulp exposure - then pulpotomy for immature and rct for mature
51
Signs of root fracture
Coronal segment mobile and displaced Sucular bleeding Vitality negative initially Transient discolouration of the crown
52
Tx of root fracture
Reposition coronal fragment if displaced | Stabilise with splint (4 w or 4m depending on location)
53
Signs of alveolar fracture
Segment mobile and dislocated Several teeth move together Misaligned teeth in alveolar segment
54
Tx of alveolar fracture
GA, reposition segment and stabilise with splint | Monitor teeth in fragment line
55
Signs of subluxation
TTP Inc mobility BUT NO DISPLACEMENT Sucular bleeding Vitality initially negative
56
Tx of subluxation
Monitor pulp vitality | Can splint to reduce discomfort
57
Signs of lateral luxation
``` Tooth displaced palatally or labially Fracture of alveolar process Immobile Metallic sound on percussion Vitality negative ```
58
Tx of lateral luxation
No occlusal interference = monitor for spontaneous repositioning Occlusal interference - reposition and splint 4 weeks RCT if necrosis occurs Severe - extract
59
Signs of intrusion
Immobile Metallic sound on percussion Vitality negative Shorter than other teeth
60
Radiographic signs of intrusion
CEJ located apically to other teeth | PDL space absent from all/part of the root
61
Radiographic signs of lateral luxation
PDL space enlarged apically
62
Tx of intrusion of immature teeth
Minor - monitor, if no spontaneous repositioning then carry out ortho repositioning - >7mm intrusion - reposition surgically or w ortho with 4 week splint
63
Signs of extrusion
Elongated tooth Very mobile Bleeding Vitality negative
64
Radiographic signs of extrusion
PDL widened apically
65
Tx of extrusion
If minor and mobile - intrude gently and splint | RCT indicated if pulpal necrosis occurs
66
Tx intrusion of mature teeth
Minor - allow spontaneous eruption, if nothing then reposition surgically or orthodontically If 3-7+mm - reposition surgically or ortho and splint RCT usually required
67
When is RCT carried out after repositioning of intruded teeth
2-3 weeks
