Management of Pre-Eruptive Intra-Coronal Resorption: A Case Report

Pre-eruptive intra-coronal resorption (PEIR) represents a unique dental disorder where the resorption occurs within the tooth structure before eruption into the oral cavity. This condition is a resorptive, radiolucent lesion confined to the dentin and may extend into the enamel in severe cases. The prevalence of PEIR remains low relative to other dental conditions. The etiology of PEIR is still unclear. Since most cases are asymptomatic, PEIR is often diagnosed incidentally during routine radiographic examinations. When patients present with symptoms, early detection and intervention are necessary to prevent complications. This case report investigates a 5-year-old Saudi girl presenting with PEIR affecting the upper left first permanent molar and lower left first permanent molar, with tooth #36 managed with indirect pulp treatment (vital pulp therapy) to preserve pulp vitality and sound tooth structure, while tooth #26 received a conventional restoration.
