Figure 5

H&E staining. ((a)–(l)) Area comprising the distal root of the maxillary first molar and the mesial root of the maxillary second molar of all groups at all time points (D: dentin, AB: alveolar bone, CEJ: cement-enamel junction, and JEA: junctional epithelial attachment, ×100, bar represents 150 μm). ((m)–(o)) Histologic analysis of the surface of inflammatory infiltration (m), alveolar bone loss (n), and attachment loss (o) of the rats in all groups. ^∗𝑃<0.05 versus control group at the same time point. ^#𝑃<0.05 versus periodontitis group at the same time point. ^※𝑃<0.05 versus the same group at baseline.
