An idiosyncratic post-traumatic tetrad: Compound odontome, dentigerous cyst, impaction, and double-dilaceration

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. Summary: 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. Parole chiave: dentigerous cyst, impacted tooth, odontome, tooth intrusion, treatment
