目的 比较不同类型牙移动所致牙周鲁菲尼小体超微结构的变化,探讨力学环境改变对牙周机械感受器的影响.方法 28只8周龄SD大鼠用随机数字表分为空白对照组(4只)、非拔牙组(12只)和拔牙组(12只),后两组再细分为3、14、28 d亚组(每亚组4只).非拔牙组:移左上和右下第三磨牙向远中,其中上颌左侧第三磨牙为有对(牙合)牙的移动牙,上颌右侧第三磨牙为移动牙的对(牙合)牙;拔牙组:拔除下颌双侧第三磨牙并移左上第三磨牙向远中,其中上颌左侧第三磨牙为无对(牙合)牙的移动牙,上颌右侧第三磨牙为无对(牙合)牙的牙齿;空白对照亚组不拔牙,不进行任何处理.实验各时间点透射电镜观察大鼠上颌双侧第三磨牙远中根牙...

OBJECTIVE: To compare the ultra-microscopic changes of periodontal Ruffini's corpuscle induced by different patterns of tooth movement, and investigate the influence of different changes of the periodontal mechanical environment on the periodontal mechanoreceptor. METHODS: Thirty-two eight-weeks-old SD rats were divided into control group (n = 4), none-extraction group (n = 12) and extraction group (n = 12), and none-extraction group and extraction group were further divided into three subgroups, namely 3 day and 14 day and 28 day. For control group, no intervention was performed. For none-ext...
