319 - Dental Management of an Immature Tooth with Severe Intrusive Luxation: A Case Report

Traumatic dental injuries are most frequent during the first 10 years of life, decreasing with age. These injuries have a higher prevalence in the primary dentition when compared to the permanent dentition of 30% to 20%, respectively. Frequently, dental trauma not only results in injury to the tooth, but also the surrounding and supporting structures.

This case report reviews the treatment of an eight-year-old female who presented to the emergency department of Cohen Children’s Medical Center (CCMC) with a 9 mm intrusion and buccal luxation of tooth #8. This tooth was identified to have an open apex and no trauma to the adjacent dentition.

To summarize, in cases with immature root development or mild to moderate intrusions ( < 3 mm and 3-6 mm, respectively) spontaneous re-eruption is the treatment of choice. Providing these teeth the time to spontaneously re-erupt limits complications such as necrosis, infection, and replacement resorption.
