Paediatric Trauma III Flashcards
what is a trauma stamp and when is it used?
A list of things that can be used to check a tooth with trauma:
- Sinus
- Colour
- Mobility
- Tender to percussion (TTP)
- Percussion
- Ethyl Chloride
- Electric pulp test (EPT)
- Radiograph
used during trauma incident to give better idea of the state of the trauma’d tooth
what is an extrusion and how would you treat it?
a trauma accident where the tooth is displaced out of the socket partially
LA - gently reposition tooth back into socket then splint
what is lateral luxation and how would you treat it?
Displacement of a tooth in socket laterally, can usually involve alveolar fracture
splint - 4 weeks!
LA - gently reposition and splint. Evaluate endodontic treatment 2 weeks post injury.
If open apex, there may be revascularisation, if its closed, most likely necrotic pulp and endo needed.
what is intrusion and how would you treat it?
tooth forced into socket axially and locked into bone.
If very intruded, surgical reposition may be required 3-7+mm
less than 3mm can be used with splint under LA or orthodontic elastic bands.
Open apex - 40% survival rate pulp
Closed apex - 0% survival rate - endo
what is a tooth avulsion and how would u treat it
tooth totally displaced from socket. [emergency situation]
Critical factors: storage medium of tooth out of mouth, saliva/milk etc. If PDL is damaged or tooth has dried out. If tooth out of mouth for 60mins+ = PDL cells are NON-VIABLE
Reimplant under LA - Splint.
Closed Apex = endo
Open apex = possible endo (if spontaneous healing doesnt occur)
what is a dento-alveolar fracture and its clinical findings?
fracture of alveolar bone which may or may not involve the alveolar socket
gingival laceration, occlusal disturbance, segments of the mouth are mobile and displaced with several teeth moving together
how do you treat a dentoalveolar fracture?
reposition any displaced segment of bone. Stabilise by splint, suture any soft tissue lacerations. Monitor pulp of teeth involved
[soft diet, good oh etc]
whats the splinting time of a dento alveolar fracture?
4 weeks
splinting time of root fracture - cervical third?
4 months
splint time of mid-root & apical third fracture?
4 weeks
what is ankylosis in dentistry?
fusion of the root to the surrounding alveolar bone
