Background:
This study evaluated Somatosensory evoked potentials (SEP), Quantitative sensory testing (QST), and thermography as diagnostic methods for nerve injury.
Methods:
From 2006 through 2011, 17 patients (mean age: 50.1 years) from OOOO Hospital who sought care for altered sensation after dental implant treatment were identified. The mean time of objective assessment was 15.2 months after onset.
Results:
SEP of Inferior alveolar nerve(IAN) was 15.87 ± 0.87 ms on the normal side and 16.18 ± 0.73 ms on the abnormal side. There was delayed N20 latency on the abnormal side, but the difference was not statistically significant. In QST, the abnormal side showed significantly higher scores of the current perception threshold at 2 KHz, 250 Hz, and 5 Hz. The absolute temperature difference was 0.55°C without statistically significance.
Conclusion:
These results indicate that QST is valuable as an objective method for assessment of nerve injury.
