AB Impacted  or  intruded  teeth  result  when  a  tooth  is  forced  deeper  into  the  alveolar  socket  or  surrounding  tissues  as  a  result  of  trauma.  The  tooth  appears  shorter  than  its  contralateral  mirror.  An  impacted  tooth  may  be  partially  visible  or  completely  hidden  by  the  gingiva  and  buried  in  the  alveolar  process.  Completely  impacted  teeth  may  erroneously  be  considered  avulsed  until  a  radiograph  demonstrates  the  intruded  position.  The  apex  of  a  completely  impacted  permanent  central  incisor  may  be  driven  through  the  alveolar  bone  into  the  floor  of  the  nares,  causing  epistaxis.  Associated  injuries  may  include  alveolar  fractures,  dental  crown  or  root  fractures,  and  oral  mucosal  or  gingival  lacerations.  Pulp  necrosis  occurs  in  15%  to  50%  of  cases.
