Effects of different treatments on the microarchitecture of molars in rats. Animals were treated with distilled water, 15% ethanol, farnesol, farnesal, chlorhexidine, blank PMs, Far-PMs and PPi-Far-PMs, respectively. After 5 weeks, the molars of rats were analyzed using high-resolution micro-computed tomography to obtain three-dimensional reconstruction pictures of the smooth-surface molars (a) and sulcal-surface molars (b). The bone mineral density (BMD, c) and bone volume per tissue volume (BV/TV, D) were quantitatively measured. Data were expressed as mean ± SD (n = 7). The Tamhane’s T2 test (*P < 0.05) was used to assess for treatment efficacy. Symbols represented statistical significance of the labeled groups with the group treated with distilled water (^#P < 0.05, ^##P < 0.01, ^###P < 0.001, ^####P < 0.0001)
