260 - Evaluation and Treatment of Pediatric Pre- eruptive Intracoronal Resorption: A Case Report

Abstract/introduction: Pre- eruptive intracoronal resorption (PEIR), also known as “pre-eruptive caries,” is a dental condition characterized by the resorption of dental tissue prior to the eruption of the tooth.1 PIER is typically found adjacent to the dentin-enamel junction, within the occlusal dentin of the tooth.2 PIER may be referred to as “occult” or hidden caries due to the presence of sound enamel and is often an incidental finding on routine radiographs.3 PEIR is often misinterpreted as traditional caries due to its radiographic appearance,3 however requires careful evaluation for determination of treatment and long term success.
Case report: This case report details a 14 year old female patient who presented to the Children’s Mercy Hospital Dental Clinic in August 2025 with asymptomatic PEIR on her permanent second molar. The patient’s medical history is significant for Apert’s syndrome. Although the exact etiology of PEIR is unknown, this case report aims to explore potential etiologies, diagnosis, treatment, and clinical considerations of PEIR.
