RESUMO
Several growth factors have been used in tissue regeneration therapy. Here we describe the use of an autologous blood clot combined with gelatin for teeth affected by severe periodontitis and vertical root fracture treated using three oral surgical procedures: periodontal flap surgery, intentional tooth replantation (IR), and tooth autotransplantation. Treatment with a blood clot improved the condition of the periodontal tissue, including reduction of pocket depth. Radiographical images demonstrated no evidence of ankylosis, and revealed the presence of alveolar bone regeneration. Our successful clinical outcome suggests that use of an autologous blood clot combined with gelatin is clinically effective for regeneration of lost periodontal tissue.

This paper describes the utility of three-dimensional (3D) images obtained with cone beam computed tomography (CBCT) for prediction of successful clinical outcome in two cases of intentional tooth replantation (IR). IR was performed for teeth affected by vertical root fracture and root perforation with local application of blood clot and oxy-tetracycline antibiotic. High-resolution 3D images demonstrated no evidence of ankylosis, but did reveal the presence of alveolar bone regeneration, suggesting a good long-term prognosis. Our observations in these cases suggested that local application of the above two materials might help to induce the regeneration of lost periodontal tissues in IR.

We evaluated and treated a 54-year-old woman with gingival swelling. Conventional intraoral and panoramic radiography did not provide sufficient information for either determining the cause of gingival swelling or planning treatment of clinical symptoms. The 3D Accuitomo XYZ Slice View Tomograph (3DX) is a compact dental computed tomography device that allowed for accurate identification and optimal treatment of the causes of gingival swelling. At four years after treatment, 3DX radiographs showed no abnormalities in treated teeth or healing of surrounding structures. We conclude that high-resolution 3D images obtained with 3DX promise to be very effective for diagnosing oral diseases and determining effective treatment.
