Concussion and subluxation

¨ A concussed tooth is TTP due to oedema and haemorrhage in the periodontal ligament

¨ A subluxed tooth is TTP and also abnormally loose, due to rupture of periodontal ligament fibres

 

 

Treatment of concussion and subluxation:

1. Occlusal relief and soft diet

2. Reduction— reposition with gentle pressure

3. Immobilisation of the injured teeth ( for patient comfort)

4. Chlorhexidine 0.2% mouthwash, twice daily

5. Follow up at 1 and 2 months post-trauma, vitality testing, radiographic assessment

6. Prognosis—minimal risk of pulp necrosis

These injuries represent minor injuries to the periodontal ligament and pulp caused by an acute impact
