Q

what instructions would you tell pt over phone if permanent has been avulsed

A
  • keep calm
  • pick tooth up by crown and not root

Q

what is the thought process of RCT in open apex avulsed tooth

Q

what are favourable outcomes following avulsed tooth

A

asymptomatic, functional, normal mobility, no sensitivity to percussion, no pathology, normal percussion, no RR, normal lamina dura

open apex - continued root formation and eruption, pulp canal obliteration expected as mechanism the pulp heals

Q

discuss alveolar fracture primary

Study These Flashcards
A

involving alveolar bone, may extend to adjacent

reposition segment, stabilise with adjacent uninjured for 4 weeks, may need xla once stability

22
Q

discuss alveolar fracture permanent

Study These Flashcards
A

complete fracture extending from buccal-palatal maxilla or buccal-lingual mandible
segment mobility, displacement of teeth moving together, occlusal disturbance, gingival laceration

reposition segment, splint 4 weeks, suture lacerations

23
Q

discuss enamel fracture tx
primary vs perm

Study These Flashcards
A

primary - smooth sharp edges
perm - bond fragment or smooth sharp edges, PA to rule of ± or luxation

6/8, 6/12

24
Q

discuss enamel-dentine fracture tx
primary vs perm

Study These Flashcards
A

primary - cover exposed dentine with GI, restore with composite
perm - bond fragment, composite bandage, line if close to pulp, PA to rule out ! or laxation

6/8, 6/12

25
discuss enamel-dentine-pulp fracture tx primary vs perm
primary - partial pulpectomy, XLA perm - pulp cap, partial pulpotomy, coronal pulpotomy immature = no apical stop for obturation w GP, use MTA/Biodentine at apex for barrier [apexification]
26
discuss crown-root fracture tx primary
remove loose fragment, determine restorability restore - cover exposed dentine w GI, if pulp exposed then pulpotomy/RCT unrestored - XLA loose fragments, don't dig
27
discuss crown-root fracture tx permanent
no exposure - fragment removal + restore only or with gingivectomy [subgingival extension], RCT + extrusion + post crown, XLA exposure - composite bandage 2 weeks, endo + extrusion + post crown, XLA, decoronation
28
discuss root fracture tx primary
coronal fragment not displaced - monitor coronal displaced but not excessive mobile - spontaneous reposition coronal displacement, excessively mobile and occlusal interference - XLA loose fragment or reposition with splint
29
discuss root fracture permanent
determine location of fracture splint 4 weeks if apical or middle third splint 4 months if cervical third RCT if required
30
what are the consequences of trauma from primary on primary dentition
discolouration - opaque/yellow = pulp obliteration - grey = may indicate necrosis, immediate discolouration may maintain viability infection - sinus, swelling, mobility delayed exfoliation
31
what are the consequences of primary trauma to the permanent dentition
- enamel defects = hypo mineralisation, hypoplasia, - abnormal crown/root morphology = dilaceration [tx via reposition, masking] - delayed eruption - ectopic tooth position - arrested development - odontome formation
32
what is the most common type of injury and when is the peak incidence
7-10 years luxation primary enamel-dentine permanent
33
prognosis of a trauma tooth depends on...
stage of root development type of injury PDL damage time between injury and tx infection
34
what is the general aims of emergency tx
retain vitality, treat exposed pulp, reduction and immobilisation of displaced teeth, tetanus prophylaxis, ABX if needed
35
name the injuries which are splinted for 2 weeks
subluxation extrusion avulsion
36
name the injuries which are splinted for 4 weeks
intrusion lateral luxation alveolar fracture root fracture apical/mid
37
what injury is splinted for 4 months
cervical fracture of root
38
what is the splint of choice
SS 0.4mm flexible passive 1 side each of tooth
39
name splint other than SS flexible
titanium trauma splint 0.2mm, rhomboid mesh structure ortho brackets + wire acrylic [if few teeth]
40
what are the main post-trauma complications of permanent teeth
- pulp necrosis and infection - pulp canal obliteration - RR - breakdown of marginal gingiva and bone
41
what is pulp canal obliteration
vital pulp response progressive hard tissue formation within pulp cavity narrowing of pulp chamber/canal tx - conservative
42
explain external surface resorption
superficial resoprtion repaired with new cementum response to injury self limiting
43
explain external inflammatory RR
non-vital tooth initiated by PDL damage diagnose - indistinct root surface, tramlines intact, kinda look PA radiolucency with lost apex tx - remove stimulus, endo with non-setting CaOH 4-6 weeks
44
explain ankylosis RR
fusion between dentine/cementum with surrounding bone, obliteration of PDL severe luxation or abulsion tx - plan for loss
45
explain internal inflammatory RR
due to progressive pu,p necrosis ballooning of canals, tramlines indistinct, root surface intact tx - remove stimulus, RCT w nonset CaOH 4-6 weeks plan for loss if progressive
46
explain direct pulp cap
tiny exposure of 1mm, 24 hr window 1. trauma sticker 2. LA, dam 3. clean area water, disinfect NaHCl 4. apply CaOH or MTA to pulp exposure 5. restore with composite review 6-8 weeks consider for enamel-dentine-pulp primary
47
explain partial pulptomy
exposure >1mm or 24hrs since trauma 1. trauma sticker 2. LA and dam 3. clean with saline, disinfect NaHCl 4. remove 2mm pulp with high speed round 5. saline soaked CW pellet until haemostasis 6. CaOH then GI, restore w composite
48
explain full coronal pulpotomy
being as partial, assess for haemostasis after saline cotton wool hyperaemic or necrotic - proceed to remove all coronal pulp CaOH pulp chamber seal with GI then composite restoration
49
explain pulpectomy open apex
1. rubber dam 2. access 3. haemorrhage control with LA and sterile water 4. diagnostic radiograph for WL 5. file 2mm short of EWL 6. dry canal, non set CaOH, CW in pulp chamber 7. GI temporary in access, evaluate CasH with ideographic extirpate and CaOH no longer than 4-6 weeks after identified as non-vital once obturation - consider composite into canal as well as access to try avoid post crown
