New alveolar bone in silk scaffold + REMD + iPS cells experimental group (B) was more intact and adequate than that in silk scaffold + EMD control group (A). New cementum almost completely covers the denuded root surface in experiment group (B), while in control group, cementum could be seen at the margin of defect where an adequate new alveolar bone could be seen (A). The sites of new alveolar bone and new cementum formation were consistent to some extent. —, Suppositional margins of defect; nAB, new alveolar bone; nPL, new periodontal ligament; →, new cementum. Photographs were taken at 100×. [Color figure can be viewed in the online issue, which is available at wileyonlinelibrary.com.]
