What are the signs and symptoms of extrusion?

Displacement +
Mobility +++
Tooth protruded/retruded
TTP+
Vitality -(most commonly)

1

Which tissues are affected in extruded teeth?

Alveolar bone intact
Severed NVB
Root face is exposed
PDL separated
Gingival cuff

2

What radiographs are taken in extruded teeth and when would follow up?

PA: PDL shows space is increased
2 weeks
4 weeks
6-8weeks
6 month
1 yr
Yearly for five yrs

3

what treatment is required for extruded teeth?

1. LA
2. Clean area
3. Reposition tooth with finger pressure
4. Place resin connect or wire splint for 2/52
5. Suture lacerations

4

What is the prognosis for extruded teeth with San open apex and closed apex?

Open apex 95%
Closed apex 45%

5

What are the symptoms of lateral luxations?

1. Tooth is displaced palatally or lingually NOT axially
2. None mobile since apex is into bone and ankylosis sound when tapped

6

Which tissues are affected in lateral luxation?

1. Communition of bone but if both sides of bone fractured then alveolar bone fracture
2. Severed NVB
3. PDL compressed
4. Possible damage to permanent tooth

7

When would you take radiographs?

2 weeks
4 weeks
6-8weeks
6 month
1 yr
Yearly for 5 years

8

How do you treat lateral luxations?

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

9

What is the likely hood of survival following laterals luxations?

Open apex: 95%
Closed apex: 25%
