MacNeal's trichrome staining of periodontal tissue regeneration at the base of the defects at 4–8 weeks postoperatively. D–F and J-L show magnified structure in the base of the defects with tooth root stained in pink, the newly formed bone or cementum dyed in red purple, the junctional epithelium dyed in blue, and the connective tissue stained in lavender (TR: tooth root, NB: newly formed bone, NC: newly formed cementum, BS: bioceramic scaffold, JE: junctional epithelium). Red triangle: the base of the defects; the dashed blue area: ingrowth of junctional epithelium; red arrows: periodontal ligament (PDL). M Schematic illustration of the distance between the base of defect to junctional epithelium (N) and the length of PDL (O)
