Traumatic displacement of a permanent maxillary incisor into the nasal cavity: A case report

Intrusive injuries are common in primary dentition, however, only a limited number of cases have been reported involving permanent teeth. The present report describes a case of severe intrusion involving a maxillary central incisor wherein the tooth was displaced beyond the apical level of the adjacent teeth, into the nasal cavity. Without adequate clinical and radiographic examination, such cases tend to be misdiagnosed as avulsion and may present with numerous complications at a later stage. The present case report highlights the importance of a meticulous clinical examination, thorough radiographic evaluation, and appropriate surgical technique for the diagnosis and management of severely intruded permanent anterior teeth.
