What happens to the PDL if an avulsed tooth is out of the socket for less than 60 minutes? |
PDL will revascularize |
|
|
Which type of dental trauma requires a flexible splint for 2 weeks? (3m) |
- subluxation - extrusion - avulsion BUT ONLY IF (open & closed apex, with EADT of <60mins) |
|
|
Which type of dental trauma requires a flexible splint for 4 weeks? (5m) |
- Luxation - Apical/middle 1/3 root # - Intrusion - Dento-alveolar # - Avulsion BUT ONLY when apex closed, >60mins EADT (open apex too) |
|
|
Which type of dental trauma requires a flexible splint for 4 months? |
- coronal 1/3 root fracture |
|
|
What does EADT and EAT stand for? |
EADT - extra alveolar dry time EAT - extra alveolar time |
|
|
What treatment would you carry out with an avulsed tooth with an open apex with >60mins EADT? |
Flexible splint 1-2 weeks DO NOT ROOT TREAT unless loss sign of vitality |
|
|
What is the difference/similarities between subluxation and concussion? |
• Subluxation - increased mobility - bleeding at sulcus - TTP - no displacement of tooth - 2 weeks flexible splint
• Concussion - no inc mobility - TTP - no displacement of tooth - no splint needed |
|
|
How do you manage an enamel-dentine-pulp fracture? |
3 options: - full coronal pulpotomy - partial pulpotomy (Cvek) - pulp cap |
|
|
If there is a pulpal exposure of 1mm what would your treatment be? (4 steps) |
Direct pulp cap. - LA & rubber dam - Clean area with water then disinfect with sodium hypochlorite - Apply calcium hydroxide (Dycal) or MTA White to pulp exposure - Restore with quality composite restoration |
|
|
How would you treat a pulpal exposure of more than 1mm or 24+ hours sonce trauma? (5 steps + 1 exception) |
Partial pulpotomy (Cvek) - LA & rubber dam - Clean area with water & disinfect with sodium hypochlorite - Remove 2mm of pulp with hi-speed, round diamond bur - Place saline soaked CW pellet over exposure until haemostasis * if no bleeding or cant arrest bleding, proceed to full coronal pulpotomy - Apply CaOH then vitrebond (or white MTA) then restore with composite resin |
|
|
Would you use ferric sulphate to arrest bleeding during a partial pulpotomy in a permanent dentition? Why? What should be used instead? |
Ferric sulphate should be avoided as it can stain the tooth. Use saline. |
|
|
When should you do a full coronal pulpotomy? |
- during a partial pulpotomy - assess for haemostasis after application of saline soaked CW - if hyperaemic OR necrotic, proceed to remove ALL coronal pulp - place CaOH in pulp chamber - seal with GIC lining and quality coronal restoration |
|
|
What is the percentage of success of partial and full pulpotomy? |
- partial: 97% - full coronal: 75% |
|
|
What is the aim of a pulpotomy? |
- to keep vital pulp tissue within the canal - to allow normal root growth (apexogenesis) - both in length & the thickness of the dentine |
|
|
What procedure would you carry out on a non-vital tooth? |
Full pulpectomy |
|
|
What 3 options could you possibly carry out on a tooth with an open apex subsequent to full pulpectomy? |
- Place CaOH in canal to promote apexification - MTA/BioDentine placed at apex to create cement barrier - Regeneration Endodontic Technique to encourage hard tissue formation at apex |
|
|
Which type of root fracture has the best prognosis? |
Apical 1/3 |
|
|
How woule you treat an apical or middle third root fracture? |
Flexible splint for 4 weeks |
|
|
The factors on a trauma stamp? |
- EPT - ethyl chloride - TTP - radiograph - percussion note - sinus - colour - mobility |
|
|
Name 4 types of resorption. |
- external surface - external inflammatory - internal inflammatory - replacement resorption (ankylosis) |
|
|
What type of medium is suitable of an avulsed tooth? |
- Milk - Saliva - Saline |
