(1)Periodontal Regeneration of Chronic Periodontal Disease Patients Receiving Stem Cells Injection TherapyAllogeneic human DPSCsLocal injection at the local periodontal defectsChronic periodontal diseaseRecruiting40Dec. 2016Improvement of baseline alveolar bone volume and clinical parameters, including probing depth (PD), Clinical Attachment Level (CAL), Quigley-Hein plaque Index (QHI), Bleeding on Probing (BoP) Not reported yetNCT02523651

(2)Use of Mesenchymal Stem Cells for Alveolar Bone Tissue Engineering for Cleft Lip and Palate PatientsSHED (autologous)Application of MSCs inside a collagen and hydroxyapatite biomaterial (Geistlich Bio-Oss®) into the defectAlveolar bone TE for cleft lip and palate patients
(secondary alveolar graft after completion of orthodontic treatment)
Unknown5Mar. 16Amount and quality of regenerated bones (CT scans)In all 5 patients bone formation closing the alveolar cleft was observed after 6 monthsNCT01932164

(3)Revitalization of Immature Permanent Teeth with Necrotic Pulps Using SHED CellsSHED (autologous)Application of scaffold-free SHED-derived pelletImmature permanent teeth with pulp necrosisRecruiting80Jul. 2017 Pulp status evaluated by dental pulp vitality tester; pulp revascularization examined by laser Doppler flowmeter; and the index of clinical examination Also, the degree of apical closure; the rate of increase in root length; and the change of root canal wall thickness.Not reported yetNCT01814436

(4)Effect on Allogenic Mesenchymal Stem Cells on Osseointegration of Dental ImplantsAllogeneic human DPSCsThe implant is dipped in the stem cell solution for 3 minutes so that the cells adhere to the titanium implant surface before placement at the osteotomy siteImprovement of implant osseointegrationEnrolling by invitation10Feb. 2017Evaluation of primary and secondary stability is measured using Resonance Frequency Analysis (RFA).
