Root resorption, M1/M2 accumulation, and cementoblast mineralization in the local injection model. (a) Representative immunohistochemical images of iNOS and CD86 in the roots of maxillary molars in the control and LPS local injection groups. Scale bars: 50 μm. (b) Representative images of HE staining in the roots of maxillary molars in the control and LPS local injection groups. Black arrows indicate the root resorption zone. Scale bars: 100 μm/50 μm. (c) Representative immunohistochemical images of OSX, OCN, BSP, and COL-1 in the roots of maxillary molars in the control and LPS local injection groups. Scale bars: 50 μm.
