# Preeruptive Intracoronal Dentin Resorption: Radiographic Diagnosis and Clinical Approach

## TL;DR

A rare dental condition called preeruptive intracoronal resorption was diagnosed in a teenager using advanced imaging, highlighting the need for early detection and specialized treatment.

## Contribution

This case study provides insights into the clinical management and diagnostic challenges of preeruptive intracoronal resorption.

## Key findings

- Preeruptive intracoronal resorption was detected via CBCT in an unerupted tooth.
- Early intervention failed to prevent pulp necrosis, necessitating tooth extraction.
- Histopathological analysis suggested a benign follicular or odontogenic lesion.

## Abstract

Preeruptive intracoronal resorption (PEIR) is a rare, asymptomatic condition typically detected incidentally on radiographic examination. Its etiology remains unclear, and clinical management is often controversial due to the lack of standardized treatment protocols.

A 14-year-old female was referred after routine orthodontic imaging revealed multiple radiolucent lesions in unerupted teeth. Cone beam computed tomography (CBCT) confirmed a hypodense intracoronal lesion in Tooth 37. Initial management included interdisciplinary assessment, pulp vitality testing, and protective restoration with glass ionomer cement following electrosurgical removal of the distal operculum. Despite early intervention, the tooth developed pulp necrosis, requiring extraction. Histopathological analysis of pericoronal tissue revealed loose connective tissue consistent with follicular origin or a benign odontogenic lesion such as a myxoma.

This case underscores the importance of early diagnosis, advanced imaging techniques, and an interdisciplinary approach in managing PEIR. Tailored treatment strategies based on lesion progression are essential, and long-term monitoring is critical to prevent complications. Further studies are needed to define clear clinical guidelines for PEIR.
