title: An idiosyncratic post-traumatic tetrad: compound odontome, dentigerous cyst, impaction, and double-dilaceration.
abstract: OBJECTIVE
  This report describes the case of a 13-year-old patient who experienced traumatic intrusion of the primary maxillary right central incisor and subsequently suffered an atypical tetrad, comprising of an unerupted compound odontoma associated with a dentigerous cyst, and an impacted, doubly dilacerated permanent maxillary right central incisor; however, the high interconnectivity of the occurrence of four pathologies together is unusual has not previously been reported.
  
  
  CONCLUSIONS
  The pathologies were detected 7 years after trauma; surgical removal of odontome along with the dentigerous cyst was performed, followed by orthodontic extrusion of the impacted double-dilacerated permanent central incisor. The 18-month follow-up shows no pathology, no gingival recession, and normal probing depth.
