Identification of alveolar bone loss and periodontal inflammation. a Micro-CT images of maxillae. Scale bar 1 mm. b Results of bone height measurement. Distances from cement-enamel junction to the alveolar bone crest of the second molar at the mesial-bifurcation (i), buccal-bifurcation (ii), distal-bifurcation (iii) and palatal-groove (iv) site were evaluated. All results are expressed as the mean ± SD. *p < 0.05. c Relative gene expression levels in the periodontal tissue. The relative quantity of GAPDH mRNA was used to normalize the relative quantity of experimental mRNA: CD68 (A), IL-6 (B) and IL-10 (C). All results were expressed as the mean ± SD. *p < 0.05
