【摘 要】
：
有症状不可复性牙髓炎是一类病变较严重的牙髓炎症,病变可发生于牙髓的某一局部,也可能涉及全部牙髓,既往的治疗方式为摘除全部牙髓以去除病变.然而近年来随着微创牙科学和活髓保存治疗理念的发展,许多文献报道活髓切断术成为有症状不可复性牙髓炎继根管治疗之后的另一种治疗选择.现就因深龋导致的有症状不可复性牙髓炎的龋损内的微生物组成和分布特点,活髓保存治疗的疗效和麻醉效果进行综述.

利用有效方式,全面缩短昏迷患者清醒时间意义重大.脑干听觉诱发电位一般被用于评价患者的脑干功能,其在患者脑干出现轻度损伤时即可发生改变.而体感诱发电位则可以体现出患者大脑半球功能、丘脑功能改变情况,经感觉系统实施系列性生理传导,能够积极展现患者受损神经功能情况.对于昏迷患者实施脑干听觉诱发电位联合体感诱发电位检测,不仅能够积极评估患者疾病预后,还有助于指导实施针对性治疗.
