Fig. 5. Inhibitory effect of BPE on alveolar bone destruction in age-related periodontitis in rats. Using reconstructed 3D images, (A) BV/TV, (B) Tb. Th, (C) Tb. Sp, and (D) BMD of alveolar bone covering the root of the first molar were measured. BV, bone volume; TV, tissue volume; Tb. Th, trabecular thickness; Tb. Sp, trabecular separation; BMD, bone mineral density. Each parameter is expressed as the mean ± SD (% or μm) of five rats per group. #p < 0.05, ^##p < 0.01 (young control vs. aged control group), *p < 0.05 (aged control vs. BPE-treated aged group).
