Significance of Early Detection and Management of Trauma-Induced Inflammatory Root Resorption: A Case Report

This case report highlights the importance of early detection and timely management of trauma-induced inflammatory root resorption (external inflammatory root resorption, EIR) following dental injuries. A nine-year-old boy presented with an extrusive luxation injury of teeth #11 and #21, accompanied by an uncomplicated crown fracture. Our proposed treatment plan was to opt for root canal treatment for both central incisors to prevent EIR; however, the patient's guardian opted for root canal treatment only for tooth #21 and to keep tooth #11 under observation, as it was vital at the time. Unfortunately, at the eighth-week follow-up visit, signs of root resorption on tooth #11 became evident. Treatment using calcium hydroxide intracanal dressings every two weeks was initiated, successfully arresting the resorption. The root canal space was subsequently obturated with bioceramic putty. At the three-month follow-up, tooth #11 demonstrated stability of the resorption site, periapical healing, and the absence of clinical symptoms and mobility. This case highlights the crucial role of immediate intervention to preserve dental tooth structure and prevent or stop root resorption. It emphasizes that inadequate or delayed management can significantly worsen the prognosis of trauma-induced root resorption.
