Microphotograph of a buccopalatal/lingual section of the 1-day experiment. (a) Maxilla. (b) Higher magnification of (a). On the pressure side, the PDL was compressed. (c) Higher magnification of (b). Extravasation of RBC was observed. (d) Mandible. (e) Higher magnification of (d). Compression of the PDL was shown, and reduced capillaries were identified. (f) Higher magnification of (e). The number of cells was reduced, and grafted MBCP+ particles were lost in the process of making the histological section; the red in (a) and (d) indicates empty spaces that were occupied by MBCP+ graft particles. Masson’s trichrome stain. Original magnification was ×12.5 for (a) and (d), ×100 for (b) and (e), and ×400 for (c) and (f).
