What radiographs are taken in extruded teeth and when would follow up?
A
PA: PDL shows space is increased 2 weeks 4 weeks 6-8weeks 6 month 1 yr Yearly for five yrs
3
Q
what treatment is required for extruded teeth?
A
- LA
- Clean area
- Reposition tooth with finger pressure
- Place resin connect or wire splint for 2/52
- Suture lacerations
4
Q
What is the prognosis for extruded teeth with San open apex and closed apex?
A
Open apex 95%
Closed apex 45%
5
Q
What are the symptoms of lateral luxations?
A
- Tooth is displaced palatally or lingually NOT axially
2. None mobile since apex is into bone and ankylosis sound when tapped
6
Q
Which tissues are affected in lateral luxation?
A
- Communition of bone but if both sides of bone fractured then alveolar bone fracture
- Severed NVB
- PDL compressed
- Possible damage to permanent tooth

- La
- Clean and reposition with finger
- Place flexible splint for 4/52 or longer if bone fractured
- RCT is indicated if tooth is discoloured and -ve vitality for 3/12 and signs of apical path
