Large calcified areas were observed in the articular discs of the temporomandibular joint from five patients suffering from articular dysfunctions. The calcified regions were always located inside the fibrous tissue of the discs. They had a woven bone-like morphological pattern and consisted of a compact mineralized tissue containing cells in irregular lacunae. In all the samples the calcified tissue was completely surrounded by a mineralizing border rich in cells and variously arranged collagen fibrils. Energy-dispersive spectrometry showed that mineralized regions contained large amounts of Ca and P. X-ray powder diffraction identified the crystals in these areas as hydroxyapatite.
在五名患有颞下颌关节功能障碍的患者的颞下颌关节关节盘中观察到大面积钙化区域。钙化区域总是位于关节盘的纤维组织内。它们具有编织骨样的形态模式，由含有不规则腔隙内细胞的致密矿化组织组成。在所有样本中，钙化组织完全被富含细胞和排列各异的胶原纤维的矿化边界所包围。能量色散光谱显示矿化区域含有大量的钙和磷。X射线粉末衍射确定这些区域的晶体为羟基磷灰石。
