what are the classification of trauma?
|
Injuries to the :
1. hard dental tissue and pulp 2. hard dental tissue, pulp and alveolar process 3. periodontal tissues 4. gingiva or oral mucosa |
|
|
Hard dental tissues and pulp:
|
enamel infraction
enamel fracture enamel-dentine fracture complicated crown fracture |
|
|
Injuries to the hard dental tissues, pulp and alveolar process:
|
crown root fractures
root fractures fracture of alveolar socket wall fracture of alveolar process |
|
|
injuries to periodontal tissues:
|
concussion
subluxation luxation (exrusion, lateral, intrusion) avulsion |
|
|
Injuries to gingiva or oral mucosa:
|
laceration
- tear abrasion - superficial wound, - rubbing or scraping, - raw, bleeding surface contusion |
|
|
General approach to managmenet of acute trauma?
|
remain calm
triage - assess level of consciousness - other injuires - oro-facial injuries clean records and documentation stabilise treat review |
|
|
How to manage enamel fracture of primary dentition?
|
smooth sharp edges
restorative |
|
|
How to manage enamel fracture of permanent dentition?
|
smooth sharp edges
restorative |
|
|
Management of complicated primary dentition crown fracture?
|
pulp therapy
- direct pulp cap - pulpotomy - pulpectomy and obturation Restoration with resin crown Extraction |
|
|
Management of complicated permanent dentition crown fracture?
|
Pulp therapy
- depends on health of the pulp and maturity of the apex and root walls - direct pulp cap - mta - pulpotomy - non-vital pulp therapy Restoration with resin crown |
|
|
Management of root fracture: Primary
|
if no significant mobility of coronal fragment
- no immediate tx indicated then review - splining not necessarily indicated If displaced or very mobile coronal fragment - extract the entire tooth |
|
|
Management of permanent dentition root fracture?
|
if mobile coronal fragment
- rigid fixation(splint) upto 2 months - recent - flexible fixation for 2-3 weeks if fracture isat CEJ, exo of coronal fragment may be indicated. need to then consider root burial, ortho extrusion,exo of root |
|
|
Types of healing of fractures?
|
healing with calcified tissue
healing with connective tissue bone and connective tissue granulation tissue |
|
|
Types of healing of pulp?
|
revascularisation
necrosis pulp canal obliteration |
|
|
Management of concussion and sublexuation of primary and permanent?
|
observation only
splinting not indicated soft diet chlorhexidine |
|
|
Management of primary dent luxation
|
Extrusive:
extraction is indicated Lateral luxation: if not excessivley mobile and if not in traumatic occlusion, leave to allow spontaneous repositioning if excessive mobility or if in traumatic occlusion then extraction |
|
|
Managemetn of permandent dent luxation?
|
disimpaction of luxated tooth
management of the alveolar fracture reposition tooth non-rigid splinting 10 - 14 days probable RCT in mature teeth |
|
|
Management of intrusion: Primary dent
|
do not extrude physicaly or orthodontically
– Direction of displacement • If apex of primary tooth has been displaced palatally, into developing permanent tooth, extraction is indicated • If apex of primary tooth has been displaced labially, away from developing permanent tooth, defer to severity of displacement criteria • If apex has been displaced labially and has fractured the labial bone plate (as seen on lateral Mx film), extraction is indicated … virtually no chance of spontaneous eruption. – Severity of displacement • If less than half crown has been intruded, good chance of spontaneous eruption over the next three months … leave and monitor • If half crown has been intruded, possibility of spontaneous eruption is reduced … allow time for spontaneous eruption, but consider extraction • If more than 75% of crown has been intruded, possibility of spontaneous eruption is very low … extraction is indicated |
|
|
Intrusion of permanent dentition
Management options? |
passive re-eruption
surgical repositioning orthodontic repositioning |
|
|
Intrusion of permanent dentition
Management based on severity of intrusion? |
< 3mm
- leave to re-erupt 3-6mm - leave to re-erupt - or apply traction to reposition > 6mm - surgical or ortho repositioning |
|
|
Management of avulsion of primary dention
|
never reimplant
|
|
|
Management of avulsion of permament dentition
|
clean
reimplant non-rigid splint 7-10 days RCT |
|
|
Avulsion of permandent dentition treatment considerations (factors)?
|
extra-alveolartime
storagemedium stage of development |
|
|
Types of injury to primary teeth which may injure developing permanent dentition?
|
intrusion
luxation injury leading to primary tooth pulp death and nectrosis giving rise to apical periodontitis |
|
|
Types of injury that may be caused to the permandnet successor?
|
enamel hypomineralisation
enamel hypoplasia crown or root dilaceration partial or complete arrest of root formation odontome formation |
