拔除第三磨牙的主要危险是损伤三叉神经的周围感觉神经分支,引起感觉功能障碍。本文对拔除第三磨牙后味觉功能的改变进行了研究。 材料和方法 17位需拔除4个第三磨牙者,分别于术前、术后1个月和6个月用两种实验测定其味觉功能:全口高于刺激阈实验和局部测定试验,实验液为NaCl,枸椽酸和盐酸奎宁溶液。另20名仅作局部麻醉,作为对照。 The main risk of removal of the third molars is damage to the peripheral sensory nerve branches of the trigeminal nerve, causing sensory dysfunction. In this paper, the removal of the third molar taste function changes were studied. MATERIALS AND METHODS: Twenty-four third molars were removed and their taste functions were measured preoperatively, 1 month and 6 months postoperatively by two experiments: full mouth was higher than stimulation threshold test and local test, and experiment Liquid is NaCl, citric acid and quinine hydrochloride solution. The other 20 were only for local anesthesia, as a control.
