Question 1

intrusion luxation

Answer 1

1) treatment
- reposition: passive, active, surgically + splint
2) incomplete root
- loosen and wait for reeruption
- open apex = monitor and possible revascularization
- better chance of healing
3) complete root
- orthodontic / surgical reposition
- RCT within 3 weeks
- flexible splint

Question 2

extrusion lucation

Answer 2

1) partial displacement of the toot haxially from socket, PDL is torn
2) displacement, mobility, sulcular bleeding, injury to pulp, percussion pain
3) increased PDL space

Question 3

extrusion luxation treatment

Answer 3

1) primary
- minor <3 mm allow tooth to reposition
- extraction is indicated with severe extrusion
- possible damage to underlying tooth
2) permanent
- reposition and flexible splint

Question 4

avulsion

Answer 4

1) tooth is completely displaced out of its socket
2) bleeding, displacement, injury to PDL
3) take radiograph to confirm its not intruded

Question 5

avulsion treatment

Answer 5

1) primary
- never replant
2) permanent
- keep tooth hydrated
- replant as soon as possible: HBSS, sold milk, viaspan, saliva

Question 6

replantation

Answer 6

1) radiograph
2) irrigate tooth with HBSS or salin
2) irrigate socket
3) replant slowly with slight digital pressure and confirm correct position with a radiograph
4) flexible splint 2-4 weeks
5) systemic antibiotics and tetanus prophylaxis

Question 7

3 possible PDL scenarios

Answer 7

1) PDL is viable
- within 15 minutes
2) viable but compromised
- storage medium
- or extraoral dry time is <60 mins
3) non viable
- extraoral dry time > 60 minutes

Question 8

splinting

Answer 8

1)help maintain position and assist healing
2) small diameter ortho wire or ligature wire or fishing line
3) flowable composite

Question 9

types of mouthgaurds

Answer 9

1) custom mouthguard)
