Psychological Stress Delays Periodontitis Healing in Rats: The Involvement of Basic Fibroblast Growth Factor

Figure 8

Immunostaining of basic fibroblast growth factor. ((a)–(l)) Area comprising the mesial root surface of the maxillary second molar of all groups at all time points (D: dentin, AB: alveolar bone, and PDL: periodontal ligament, ×200, bar represents 100 μm). The boxed areas indicate a higher magnification (×400). ((m)-(n)) Quantitative analysis of the number of immunoreactive cells (m) and the intensity of staining (n). ^∗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.
