Extrusion and Lateral Luxation Flashcards
What is disrupted in both extrusion and lateral luxation?
Periodontal tissues as well as pulp
What is commonly damaged in lateral luxations?
Alveolar plate
What are complications generally worse for?
Mature teeth
What are clinical findings of extrusive luxation?
Often loose at initial presentation
What are radiographic findings of extrusion?
What factors effect healing of extrusion?
Whether repositioning has been optimal
What are clinical findings of lateral luxation?
Often locked into place by fractured alveolus
What are radiographic findings of lateral luxation?
What factors effect healing of lateral luxation?
Complex healing pattern resulting from combined pulpal and periodontal injuries
How would you treat two conditions?
If these injuries are seen soon after injury they can usually be repositioned and splinted
What differences, if any, are there between treatment of two injuries?
Treatment is similar in both cases but, laterally luxated tooth usually needs to be disengaged before it can be splinted
What does successful repositioning of a tooth manually require?
See injury early, certainly within 48 hours and ideally same day
What complications may occur?
Pulp death and pulp canal obliteration
What is pulp death very common in?
Mature teeth, particularly following lateral luxation
What does pulp canal obliteration occur more frequently in?
Teeth with open apices which have suffered severe luxation injuries
