Figure 2. Histological comparison of normal and hypofunctional periodontium after bite-raising for 3 wks at the disto-apical third region of the distal root. The reduction in periodontal width, atrophic changes, and derangement of the functional principal collagen fibers in the hypofunctional periodontium group (B) could be observed when compared with the normal periodontium group (A). PDL, periodontal ligament; B, alveolar bone; T, Tooth; Bar = 100 µm.
