Undecalcified ground sections parallel to the long axis of the second molar and of approximately 70 μm thickness were fabricated from control (“cont”) animals and those that had been treated with LMHF vibration therapy at low (“0.05”) or high (“0.2”) magnitude. Samples were taken either 1 (1w) or 3 (3w) weeks after vibration therapy. Bone volume and trabecular thickness, number, separation, and spacing were quantified. Data are mean ± standard deviation and were statistically analyzed using ANOVA with Tukey-Kramer post hoc test, with statistical significance (*,**) accepted at P < 0.05.

(b) Histological images. Rats were injected peritoneally with tetracycline, calcein, and alizarin complexone at various periods prior to specimen generation (see Materials and Methods). Images captured by light and fluorescence microscopic observations of the specimens are shown here (overlay). The strong line of fluorescence at the perimeter of the samples denotes newly formed bone and distinguishes this from the existing bone at the center. At 1 week (top row), newly formed bone can be seen at the upper side in the extraction socket within the apical region of the molar teeth. A dark area observed in the extraction socket region within the section is a blood clot. At 3 weeks (bottom row), more abundant bony trabeculae can be seen and the area of blood clot decreases.
