Comparative StudyComparison of current perception threshold electrical testing to clinical sensory testing for lingual nerve injuries.
We performed a retrospective study of lingual nerve injury assessment comparing the techniques of current perception threshold testing versus clinical sensory testing. ⋯ The significant correlations observed in the present study indicate that current perception threshold can be a complementary or alternative tool in the assessment and evaluation of lingual nerve injuries.

Iatrogenic displacement of lower third molar roots into the sublingual space: report of 6 cases.
To describe the clinical characteristics of patients who have had sublingual displacement of a mandibular third molar root, to identify potential risk factors, and to provide the clinician with information on how to prevent and treat this complication. ⋯ Accidental displacement of a lower third molar root into the sublingual space is an uncommon complication. When the fragments are small, surgical removal of the displaced roots seems to be unnecessary, because patients usually remain symptom free. When surgery is needed, a considerable incidence of complications should be expected.

Risk factors for neurosensory disturbance after bilateral sagittal split osteotomy based on position of mandibular canal and morphology of mandibular angle.
The aim of the present study was to evaluate the potential morphologic risk factors for postoperative neurosensory disturbance (NSD) after bilateral sagittal split osteotomy. ⋯ The frequency of NSD after bilateral sagittal split osteotomy in Class III cases was dependent not only on the position of mandibular canal, but also on the length of the mandibular angle. A lateral course of the mandibular canal and a long mandibular angle appeared to result in a high risk of injury to the inferior alveolar nerve, resulting in NSD owing to a compromised splitting procedure.
