Three-dimensional analysis.

<p>(<b>A, B and C</b>) Three-dimensional images of rats with periodontitis (P); A: buccal side view, B: occlusal surface view, C: palatal side view. (<b>D, E and F</b>) Three-dimensional images of periodontitis with ultrasound-microbubble-mediated application of NF-κB decoy oligodeoxynucleotide (ODN) (PUM) in rats; D: buccal side view, E: occlusal surface view, F: palatal side view. <b>(G)</b> Alveolar bone volume in control, P, and PUM rats. Graphic depiction of alveolar bone volume (mm³) in the rats in each group. Results are expressed as the mean ± standard error (n = 6) of the volume of alveolar bone. *P < 0.05.
