  		Figure 1. Schematic diagram illustrating experimental design, P. gingivalis infections, plaque sample collection, PCR analysis, ESWT administration, euthanasia, and alveolar bone collection. (For details, see "Materials & Methods".) Rats were killed at 0, 3, 6, and 12 wks post-ESWT application.

  		Figure 2. Effect of ESWT on P. gingivalis-induced maxillary, mandibular, and total alveolar bone resorption in rats. Each point represents the mean alveolar bone resorption in mm, as a summation of 2 sites per tooth and 3 teeth in each quadrant (n = 6 rats per group/per timepoint; four timepoints = 0, 3, 6, and 12 wks). The vertical brackets denote 1 standard deviation from the mean. ‘Inf’ denotes infected and untreated control rats, and ‘Uninf’ denotes uninfected control rats.

  		Figure 3. Representative digital radiographic images of P. gingivalis-infected (Gr I: left maxilla), infected, and ESWT-treated rats at 100 impulses (Gr II: left maxilla), 300 impulses (Gr III: left maxilla), and 1000 impulses (Gr IV: right maxilla), and control uninfected and untreated (Gr V: right maxilla) of rat jaws (n = 6 rats per group/per timepoint; four timepoints = 0 (baseline), 3, 6, or 12 wks post-ESWT). The horizontal lines denote the bone level and CEJ (cemento-enamel junction) level on the radiographs. The vertical lines denote examples of the 6 sites in each quadrant where interproximal vertical alveolar bone measures were obtained.
