Abstract

Quantitative testing of the sensory thermal thresholds testing was applied at sites innervated by the third division of the trigeminal nerve in 20 patients with no reported sensory impairment and in 20 subjects with iatrogenic nerve injuries after third molar surgery. In the control group sensitivity to cooling was significantly greater than the sensitivity to warming at all sites. The labial mucosa innervated by the inferior alveolar nerve was significantly more sensitive to thermal changes than either the mental region or the lingual mucosa. At sites supplied by nerves that had been injured, there were raised thresholds to both warming and cooling compared with the control group, and with uninjured contralateral sites. The results indicate that this test can identify iatrogenic lingual and inferior alveolar nerve injury with reference to a control group but because of spatial variation selection of control sites for comparison should be done cautiously.
