Conservative management of progressive external inflammatory root resorption after traumatic tooth intrusion
A healthy 10.5-year-old female patient had history of dental trauma which resulted in complete intrusion of tooth [Figure and ]. Patient initially seen by an orthodontist for forced orthodontic extrusion of intruded tooth. After 6 months of orthodontic treatment intruded tooth repositioned back to its original position []; and direct composite filling was done to build the broken incisal edge []. After removal of orthodontic appliance Grade 2 mobility was noticed in tooth 11 and post-treatment radiograph revealed sever external apical and cervical root resorption with large periapical radiolucency around tooth 11 []; so patient was referred for management of external root resorption.\nHer clinical examination showed mixed dentition with satisfactory oral hygiene. Tooth 11 had Grade 2-3 mobility, was in good occlusion and not tender to palpation or percussion. Tooth 11 responded negatively to pulp sensibility testing (thermal and electrical), while teeth 12, 21, and 22 responded positively. Although, clinical and radiographic findings were alarming for the treatment success and long-term prognosis of tooth 11 but still after discussing plan with parents decided to preserve the tooth 11.\nA pulpless and an infected root canal system with chronic apical periodontitis, apical inflammatory root resorption, and lateral inflammatory root resorption (at the cervical level, on both mesial and distal aspects).
