Özet

Intrusive luxation is a serious dental injury that causes damage to the pulp and supporting structures of a tooth because of its dislocation into the alveolar process. This paper presents the case of the re-eruption of a severely intruded immature permanent incisor with a crown-root fracture. A 9-year-old boy was referred to the clinic 1 day after a fall. Clinical and radiographic examinations revealed intrusive luxation of the immature left permanent incisor and a crown-root fracture without pulp exposure. Palatal gingivectomy was done 2 weeks later to facilitate re-eruption. Root canal therapy with intracanal calcium hydroxide paste was initiated during the first month owing to severe spontaneous pain. Six months later, the tooth re-erupted to a normal position, after which root canal obturation and a final esthetic restoration were done. The present case demonstrates the possibility of obtaining re-eruption of intruded immature permanent teeth with interim medication (calcium hydroxide) in the root canal.
