Managemment of luxation injuries (primary dentition) Flashcards
How should a concussion injury be managed?
No treatment necessary. Observe.
Recall 1 week and 2 months.
What are the clinical presentations of a concussion injury?
tooth tender to touch. No mmobility and no sulcular bleeding.
No radiographic anomalies and normal periodontal space.
What are the clinical presentations of a subluxation injury?
Tooth has increased mobility bbut hhas not been displaced.
May have some bleeding from the gingival crevice.
Radiographically usually normal periodontal space. Occlusal radiograph is recommended to screen for displacement or presence of root fracture.
How should a subluxation injury be managed?
No treatment. Patient should be instructed to brush with soft brush and CHX (0.1% and alcohol free) to the area with cotton swabs twice a day for a week.
Follow-up should be at 1week, 2 months.
Crown discolouration might occur but no treatment required unless a fistula develops.
What are the clinical signs of an extrusive luxation?
Partial displacement of the tooth out of the socket.
The crown may appear elongated and there may be excessively mobile.
Radiographically increased PDL space apically
How should an extrusive lluxation injury of the primary dentition be managed?
Depends on the degree of displaceent, mobility, root formation and childs ability to cope.
If <3mm, in an immature developing tooth, careful repositioning or spontaneous eruption.
If more than 3mm, extraction.
FOllow up, 1 week, 2 months, 6 months, 1 year. If dark discolouration, follow carefully for infection.
What are the clinical signs of a lateral luxaation injury of the primary dentition?
Tooth is displaced usually in a palatal/lingual or labial direction.
Will be immobile.
Radiographically, increased periodontal space apically best seen on an occlusal exposure which can also show the relation of the displaced tooth with its permanent successor.
How should a lateral luxatioon injury of a primary tooth be managed?
If no occlusal interferences, tooth should be allowed to reposition spontaneously.
If minor occlusal interferences, slight grinding indicated.
If severe occlusal interference, tooth can be gently repositioned by continued labial and palatal pressure after LA.
If severe displacement, i.e crown in labial direction, extraction.
