DESCRIPTION AND CLINICAL APPEARANCE
The tooth is partially displaced out of its socket.
The tooth appears elongated and is usually displaced palatally. The tooth is very loose, with bleeding from the gingival sulcus.
The tooth appears dislocated, with the apical part of the socket empty.
BIOLOGICAL CONSIDERATIONS AND TREATMENT PRINCIPLES
The impact results in partial disruption of the PDL attachment as well as rupture of the apical neurovascular bundle, causing increased mobility of the tooth and pulpal infarction (coagulation necrosis). The disruption of the neurovascular supply is frequently reflected in ne/>
