Figure 2.

Histological view of a well-healed sample (#1) in the experimental group (H&E staining). (A) Low magnification. White arrowhead apical end of the junctional epithelium; black arrowhead, coronal end of the new cementum; yellow arrowhead, coronal end of the new bone; star residual graft material (scale bar=1 mm). (B) Higher magnification at the junctional epithelium (scale bar=100 µm). (C) Higher magnification at the middle area of the root surface (scale bar=50 µm). (D) Magnified view at the notch (scale bar=100 µm). (E) Higher magnification of the residual graft material (scale bar=250 µm).
