a Schematic illustration of the operations involved in animal experiments. b Micro-CT images of the maxilla of rats after different treatments. The scale bar is 1 mm. c H&E stained images of the maxillary slices of rats after different treatments. Inflammatory cell infiltration is indicated by arrows, and the arrangement direction of collagen fibers is indicated by dotted lines (n = 3). The scale bar is 200 μm. d Immunofluorescent staining of pro-inflammatory factors (IL-1β and TNF-α) in the maxillary slices of rats after different treatments (n = 3). The scale bar is 500 μm.
