Figure 1. Photomicrographs of sections of mandibular condyle stained with hematoxylin and eosin. (A) Normal rabbit; (B) non-functional side of TMJ 3 wks after unilateral removal of teeth; (C) functional side of TMJ 3 wks after unilateral removal of teeth; (D) non-functional side of TMJ 6 wks after unilateral removal of teeth; and (E) functional side of TMJ 6 wks after unilateral removal of teeth. F, fibrous layer; PC, pre-chondroblast layer; FC, functional chondroblast layer; and HC, hypertrophic chondroblast layer. Arrows 1 & 2 = irregular nuclei; arrows 3 & 4 = round and oval nuclei. Bar = 40 µm.

Figure 2. Photomicrographs of sections of mandibular condyle stained with safranin O. (A) Normal rabbit; (B) non-functional side of TMJ 3 wks after unilateral removal of teeth; (C) functional side of TMJ 3 wks after unilateral removal of teeth; (D) non-functional side of TMJ 6 wks after unilateral removal of teeth; and (E) functional side of TMJ 6 wks after unilateral removal of teeth. F, fibrous layer; PC, pre-chondroblast layer; FC, functional chondroblast layer; and HC, hypertrophic chondroblast layer. Arrows: safranin O staining with an intensity obviously higher than normal.
