Root resorption is a common squeal of traumatic injury to the dentition. Its progression can be minimized by early diagnosis and appropriate treatment. This case report presents the diagnosis and management of a case of trauma induced trio of apical root resorption, intraradicular root resorption and infrabony defect in maxillary central incisor. The main aim in treating such cases of resorption is to limit the inflammatory response at the periapical region so as to halt the resorptive process. To allow faster regeneration of the periodontal tissues, Platelet rich fibrin (PRF), a second generation platelet concentrate was used as an apical matrix over which MTA plug was given. The periodontal defect was managed with the help of localized antimicrobial photodynamic therapy (aPDT).
牙根吸收是牙列创伤常见的后遗症。通过早期诊断和适当治疗可将其进展降至最低。本病例报告介绍了一例上颌中切牙因创伤导致根尖牙根吸收、根管内牙根吸收和骨下缺损三联症的诊断和处理。治疗此类吸收病例的主要目的是限制根尖区的炎症反应，从而停止吸收过程。为使牙周组织更快再生，使用了第二代血小板浓缩物富血小板纤维蛋白（PRF）作为根尖基质，并在其上放置MTA充填物。借助局部抗菌光动力疗法（aPDT）处理牙周缺损。
