Pre-Eruptive Intracoronal Resorption: Report of Two Cases.

Background and Clinical Significance: Pre-eruptive intracoronal resorption is a rare developmental anomaly resembling occlusal caries despite the absence of an external breach. Case Presentation: We report of two cases. The first case involves a 9-year-old girl with PEIR of tooth 24 that was not identified on a panoramic radiograph taken one year earlier. The lesion later became clinically evident, presenting with symptoms and discoloration, and progressed to irreversible pulpitis requiring pulpotomy. This case highlights the importance of careful interpretation of paediatric panoramic radiographs and timely intervention to preserve pulp vitality in developing permanent teeth. The second case concerns a 16-year-old girl in whom PEIR was incidentally detected on cone-beam computed tomography (CBCT) in tooth 38. As the tooth has not yet erupted, its future clinical presentation and progression remain uncertain. To the best of the authors' knowledge, there are no published reports specifically describing PEIR in patients from the Baltic region.

Conclusions

Early radiographic detection of pre-eruptive intracoronal resorption is essential to prevent pulpal involvement and improve treatment outcomes, particularly when combined with careful interpretation of routine paediatric radiographs to minimize the risk of delayed diagnosis. This case emphasizes the importance of recognizing asymptomatic disease progression and integrating multidisciplinary approach to provide individualized treatment planning.
