Figure 4. Morphological changes from the gross to the cellular level. (A) Prone view of the experimental rat shows the snout shortened and deviated to the treated side and twisted around the sagittal axis (arrow) after immobilization of the left premaxillary suture at 8 wks. Bar, 10 mm. (B) No snout deviation for the control rat. Bar, 10 mm. (C) Strong positive dentin matrix protein-1 staining for newly formed bone bridge and mature bone for the experimental groups at the 8th wk (arrow). Bar, 50 µm. (D) Positive dentin matrix protein-1 staining was seen only in the mature bone at the 8th wk for the sham rats (arrow). Bar, 50 µm.
