Transplantation of Bone Marrow Mesenchymal Stromal Cells for Periodontal Regeneration
- Conditions
- Chronic Periodontal DiseaseAggressive Periodontitis
- Interventions
- Biological: Transplantation of allogeneic MSCs in periodontal disease
- Registration Number
- NCT05975892
- Brief Summary
The goal of this study is to evaluate the capacity of allogeneic bone marrow mesenchymal stromal cells (MSC) to induce bone regeneration in patients with periodontal disease. MSC cultured are loaded on a collagen scaffold, included into autologous platelet rich plasma clot and implanted in the bone defect.
- Detailed Description
The clinical protocol is designed to evaluate the bone regeneration capacity of allogeneic MSCs for the treatment of patients with chronic or aggressive periodontal disease. Patients with either a 2- or 3-wall intrabony defects are included in this study. A bioengineering construct, constituted by allogeneic MSCs and a collagen scaffold, is incorporated into platelet rich plasma (PRP) clot, which is implanted at the bone defect site. Follow up of treated tooth are assessed by clinical evaluation, intraoral radiography and cone-beam CT.

Group Intervention Description Allogeneic MSCs transplantation in periodontal disease Transplantation of allogeneic MSCs in periodontal disease Allogeneic MSC harvested and cultured in osteogenic medium are seeded on collagen scaffold, mixed with autologous platelet rich plasma clot. The MSCs construct (MSCs/Coll/PRP clot) is implanted in the bone defect.
- Primary Outcome Measures
Name Time Method Change in clinical attachment level (CAL) Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation Expressed as the distance in millimeters from the cemento-enamel junction (CEJ) to the bottom of the probable gingival/periodontal pocket.
Change in bone density Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation Changes in the density of the periodontal bone defect will be detected by Cone beam Tomography
Change in Tooth Mobility (TM) Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation Changes from baseline in tooth mobility will be recorded.
Change in probing pocket depth (PPD) Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation The distance from the gingival margin to the bottom of the gingival sulcus/pocket, is measured by means of periodontal probe.
Gingival recession (GR) Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation Exposure of the tooth through apical migration of the gingiva will be recorded as the distance in millimeters from the CEJ to the gingival margin
Change in bone depth Follow-up includes evaluation at 3, 6, 9 and 12 months post-transplantation The vertical bone defects will be assessed by X-rays. The postoperative depth of the intrabony defect will be calculated from the distance between the cemento-enamel junction and the bone crest on the preoperative and postoperative radiographs at the same magnification.
