Management of Intrusive Luxation of Labially Erupted Immature Maxillary Incisor: A Case Report

Intrusive luxation is one of the most severe types of dental trauma, which causes damage to the pulp and supporting structures of a tooth. Intrusive luxation is associated with an increased risk of pulp necrosis and the development of inflammatory or replacement resorption. Thus, the case report presents a severely intruded immature maxillary incisor with an uncomplicated crown fracture in a seven-year-old boy. The tooth was also ectopically erupted labially with the presence of a supernumerary tooth at the palatal side, which made the management complex. Spontaneous re-eruption was chosen as the treatment option given that the tooth had an immature root formation. The supernumerary tooth was extracted during the first visit to enhance the re-eruption of the intruded tooth. Further review after four months revealed signs of external root resorption and apical periodontitis, thus a root canal therapy with intracanal calcium hydroxide paste was immediately initiated. Radiographic evidence of a calcific barrier formation at the apex was observed after six months with no external root resorption. The tooth had re-erupted completely and migrated into arch alignment. At the end of 24 months, root canal treatment was completed with a favorable prognosis. Subsequent assessments were planned annually for a minimum of five years.
