Primary incisor intruded through the nasal cavity: a case report.

Intrusive luxation may cause complications for the primary tooth and generate adverse sequelae in the permanent successor. Although intrusion is prevalent in the primary dentition, full intrusion is a rare event that requires specialized treatment and a multidisciplinary approach. This article describes the case of a 1-year-old girl who presented with traumatic displacement of the maxillary left central incisor into the nasal cavity. The parents sought treatment 1 month after the child sustained the injury, and the impacted tooth was removed through her left nostril under general anesthesia. Four-year clinical and radiographic follow-up revealed no adverse sequelae.
