Figure 4: High magnification images of aniline blue staining. Capital letters A–I correspond to the treatment groups. Newly formed bone (NB) appears as a homogenous dark blue area, which includes osteocytes. The remaining -TCP shows a homogenous white area (asterisk). Bony bridging was nearly complete in groups F and G. Less residual -TCP was seen in group G. Original magnification 100x; scale bar = 200  m.
