# Ortho-Endo Management of Traumatically Intruded Immature Incisors: A Case Report of Novel Interventional Approach With 20 Months Follow-Up

## TL;DR

A 9-year-old girl's severely injured teeth were successfully treated with a combination of orthodontic and regenerative procedures over 20 months.

## Contribution

A novel interventional approach combining orthodontic and regenerative endodontic procedures for traumatized immature teeth.

## Key findings

- Successful correction of tooth rotation and apical displacement through orthodontic intervention.
- Regenerative endodontic procedures using i-PRF effectively addressed pulp necrosis and resorption.
- 20-month follow-up showed favorable outcomes and long-term stability of the treated teeth.

## Abstract

The case report describes the successful interdisciplinary management of a nine-year-old girl who suffered from traumatic intrusion and rotation of her immature teeth with 12 mm apical displacement of teeth 11 and 21 and 10 mm of teeth 12 and 22. It emphasizes the importance of a comprehensive and contemporary approach, which includes orthodontic intervention and regenerative endodontic procedures (REP). The report follows the CARE (case report) guidelines. The patient was initially observed for four weeks to see if there was potential for spontaneous re-eruption. After eight weeks of orthodontic intervention, the rotation was corrected. However, negative pulp sensitivity and external inflammatory (infection-related) resorption (EIR) occurred, which led to REP using injectable platelet-rich fibrin (i-PRF). Follow-ups over 20 months showed the favorable outcomes of the treatment. A long-term perspective is essential in understanding the outcomes and potential complications associated with traumatic dental injuries (TDI) in children. The case report highlights the importance of collaboration between orthodontists and pediatric dentists, among other specialists. It provides valuable insights into the complexities of managing TDI in children and highlights contemporary regenerative strategies as viable solutions.
