The evaluation of the intractable chronic pain in psychosocial factor and specificity symptom

牙科治疗后的三叉神经病变是最难治疗的疾病之一。神经受中度或重度损伤者，常出现长时间的感觉异常。本研究的目的是猜测神经损伤的严重程度可以用电和触觉检测阈值来衡量。评估感觉减退的强度和感觉不良的质量对于准确评估患者的感觉损伤和主诉非常重要。高于2.15 mA的电检测阈值有异常感觉延长的趋势。通过定量感官测试，我们可以大致预测新鲜病例的持续异常感觉。

Trigeminal neuropathy following dental treatment is one of the most difficult conditions to treat. Prolonged abnormal sensation tends to be observed in cases whose nerves were moderately or severely damaged. The purpose of this study was to guess that the severity of nerve injury could be measured with electric and tactile detection thresholds.Assessing not only intensity of hypoesthesia but also quality of dysesthesia is important to evaluate precise patient's sensory damage and complaint. And the electrical detective threshold higher than 2.15 mA showed a tendency of prolongation of abnormal sensation. Using quantitative sensory testing's, we can roughly predict prolonged abnormal sensation in fresh cases.
