title: Unusually intruded primary upper incisor: potential threat after 7 years of asymptomatic course. Diagnosis and treatment.
abstract: BACKGROUND
  Misdiagnosis of traumatic injuries can lead to inadequate treatment and complications both in the short and in the long term. Diagnosis and treatment of a patient who underwent an unusual dental trauma to the primary teeth is described.
  
  
  METHODS
  A misdiagnosed deeply intruded primary upper central incisor caused massive bleeding after seven years of asymptomatic course. The adequate diagnosis and management of the intrusion and oronasal connection is described. Furthermore, the importance of a thorough dental examination is addressed in the discussion.
  
  
  CONCLUSIONS
  The proper immediate diagnosis and knowledge regarding traumatised mixed dentition is important to reduce the extent of damage and late complications. That is why every child that undergoes head injury should be examined by a dental professional.
