Extrusion

The tooth has been partially released from its bone socket and appears elongated.

Clinical

• Tooth appears elongated with increased mobility

Radiological

• Tooth is shifted from its alveole.
• The alveole appears empty in the apical area
• Additional fracture in the root area should be ruled out

Therapy

• Reposition and splinting for approx. 2 weeks
• No root canal treatment even in the case of initial absence of reaction to the sensitivity test, if regeneration of the pulp seems realistic (most likely with slight extrusion and open apex)

Prognosis

• Vitality of the pulp maintained in >70% of cases (especially with open apex)
• Obliteration as late sequela in many cases
• Increased risk of pulp necrosis in the case of unfilled dentine wounds or exposed pulp
• Resorptions in <10% of cases (usually transient resorptions)
