A
- when there are few abutment teeth
12
Q
what is foil temporary splint
A
- very old method of splinting

13
Q
what is kalzinol
A
- a ZOE based material to cement it in place
14
Q
what are dento-alveolar fractures
A
- don’t have displacement of teeth in sockets
- some mobility
- there has been damage to alveolar bone holding teeth in
- normally 3 or 4 teeth
- teeth are secure in sockets but bone holding them in has been fractured
15

A
- numb area and lift bone and put it back where it should be

A
- 2 weeks
- 4 weeks

20
Q
what is included in a trauma sticker/stamp
A
- mobility
- TTP
- percussion note
- colour
- sinus/tender
- thermal
- Electric
- radiograph
21
Q
what is an avulsion
A
- tooth comes completely out of socket
22
Q
what are the critical factors for avulsion re-implantation
A
- extra-alveolar dry time (EADT)
- extra-alveolar time (EAT)
- type of storage medium
23
Q
what is EADT
A
- extra alveolar dry time
- tooth out of mouth in air, not in any storage medium or anything
24
Q
what is EAT
A
- extra-alveolar time
- amount of time out of mouth and dry including time it has been in storage medium
25
what do you do if patient attend with tooth already replanted
- do not remove
- follow instructions on splinting
- radiograph to establish root development
26
when is PDL viable mostly after avulsion
- replanted immediately or very shortly after
27
when is PDL viable but compromised after avulsion
- kept in saline/milk, total dry time <60 mins
28
when is PDL non-viable after avulsion
- dry time >60 mins regardless of what happened after this time
29
when are all PDL cells non-viable after avulsion
- after dry time of 60 mins or more
30
what advice should you give teacher/parent over phone if tooth has avulsed
- hold tooth by crown only
- wash in cold running water for 10 seconds
- replace in socket and child bites on tissue
- or store in milk/saliva/normal saline if person doesn't want to replant tooth
- seek immediate dental advice
31
what are the periodontal outcome of healing after avulsion
- regeneration
- PDL/cemental healing
- bony healing
- uncontrolled infection
32
what are the pulpal outcomes of healing after avulsion
- regeneration
- controlled necrosis
- uncontrolled infection
33
what is controlled necrosis for pulpal outcomes after avulsion
- elective disinfection
- know that tooth is going to become non-vital so take live bit out of tooth before it dies and causes infection
- stopping the inevitable
34
what do you do if EAT<60 minutes and tooth has been stored in appropriate storage medium after avulsion
- replant tooth under La
- flexible splint 14 days
- consider antibiotics and check tetanus status
- carry out pulp extirpation at 0-10 days unless apex is open
35
what do you do for immature teeth if EAT<60 mins after avulsion
- if not going to root treat then need to monitor clinically and radiographically for signs of continued growth vs loss
- review after 2 weeks to remove splint, 4 weeks, 2 months, 3 months, 6 months then yearly
- if tooth non-vital extirpate pulp and refer to paeds specialist
36
what do you do for mature teeth if EAT<60 mins after avulsion
- after replantation and splinting, remove pulp ASAP
- place antibiotic-steroid with non-setting CaOH
- obturation with GP within 4-6 weeks
- refer to specialist
- review 3,6,12 months then yearly
37
what to do for teeth than have been >60 mins EAT and apex is closed after avulsion
- aim for bony healing
- extra-oral endo can be carried out before replantation
- replant tooth under LA
- splint for 4 weeks
- review 3, 6, 12 months then yearly
38
why can you do extra-oral endo if tooth has been >60 mins EAT after avulsion
- time isn't a worry anymore as PDL cells are already lost now
39
what to do for teeth that have been >60 mins EAT and apex is open
- not going to get PDL healing
- small chance pulp will revascularise
- don't root treat unless signs of loss of vitality
- replant tooth under LA
- splint for 4 weeks
- consider antibiotics
- check tetanus
- monitor closely for signs of necrosis and root development
- review 2 weeks, 4 weeks, 2 months, 3 months, 6 months then yearly
40
when should you not replant tooth after avulsion
- almost never
- if very immature apex and EAT>90mins
- child is immunocompromised
- child needs other emergency treatment
- young child finding it difficult to cope
41
when should you carry out sensibility tests on avulsed teeth
- at time of injury
| - 1 month, 2 , 3 then 6-monthly for an average of 2 years
42
what do you monitor with radiographs on avulsed teeth
- root development = width or canal and length
- comparison with other side
- internal and external inflammatory resorption
43
what should you do for pulpectomy
- extirpate pulp and place CaOH for no longer than 4-6 weeks
- MTA plug and heated GP obturation
44
what is the name of MTA we use
- MTA angelus
| - sets in 15 minutes
45
what is the 5-year pulp survival for avulsions
- open apex = 30%
| - closed apex = 0%
46
what is the 5-year resorption for avulsions
- frequent in both open and closed apex
