Research Abstract	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.
