Intentional tooth replantation is considered as a treatment option for preserving the natural dentition. The indications for performing intentional tooth replantation include refractory apical periodontitis, avulsion and teeth with procedural accidents such as root perforation. We followed up changes in symptoms for three patients based on information obtained by 3DX® Multi-Image micro Computed Tomography (3DX), who were diagnosed with chronic apical periodontitis and received intentional tooth replantation. We removed the affected tooth, resected the root apex, and sealed the resected root end surface and perforation sites with 4-META/MMA-TBB resin. The three patients, who complained of occlusal pain, percussion pain and apical discomfort before the treatment, were clinically asymptomatic with normal occlusal function after the intentional tooth replantation. In addition, the teeth showed no radiographic evidence of root resorption or ankylosis. These findings suggested that intentional replantation may be a useful treatment for teeth in cases where other procedures are likely to fail.
