To study the influence of psychological stress on the tissue structure of the temporomandibular joint, the variation of the tissue structure of the temporomandibular joint was observed under psychological stress in rat. Thirty-six Wister male adult rats were subjected to the following stimulating factors: electroshock, movement constraint, climate change and food tempting, in order to let them under psychological stress (the experimental group). Twelve rats were not subjected to any stimulating actions(the normal control group). Then the rats of the experimental group were executed at three weeks, six weeks and six weeks after ceasing stimulation, each with twelve rats. The control group rats were executed at the same time as the last batch of the experimental group. The change of tissue in temporomandibular joint was observed with microscope. The results show that the collage was exposed and broken in TMJ disc and condyle, especially in rats of the sixth week group. In the recovered group, the condylar cartiage was seen to start to recover. The change of TMJ in each group sees significant difference as a whole, P<0.01. The third week group and the control group, the sixth week group and the control group, the sixth week group and the resumed group were shown to be statistically significantly different, respectively, P<0.05. The others were not statistically significantly different, P>0.05. It is concluded that long time psychological stress can lead to injuries of temporomandibular joint; while these injuries can be recovered by removing the psychological stress.

articleAbstract=过观察处于心理应激状态的大鼠颞下颌关节组织结构的变化，探讨心理应激对大鼠颞下颌关节组织结构的影响。将48只成年Wistar雄性大鼠随机分为实验组和空白对照组，其中实验组36只，空白对照组12只。对实验组施加电击、制动、气候箱、食物诱惑等刺激，使实验组大鼠处于心理应激状态。将实验组分别于3周、6周和刺激去除后6周时间点各处死12只；对照组12只同实验组最后一批一起处死。取颞下颌关节制作病理切片，光镜下分别观察关节盘、关节软骨、关节骨质和滑膜的病理变化。结果显示，实验组出现一些关节软骨变薄、胶原纤维脱落、关节盘裂隙等病变，其中6周组病变最为严重，恢复组出现修复性改变。各组间病变总体变化有差异，P<0.01。其中，实验3周组、实验6周组与对照组之间病变有差异，实验6周组与恢复组之间病变有差异，P<0.05；其余组与组之间差异无统计学意义，P>0.05。由此推测，长时间心理应激状态对大鼠的颞下颌关节组织结构有影响。应激状态去除后，其颞下颌关节的病理性改变有所恢复。,
