Physical neurosensory testing versus current perception threshold assessment in trigeminal nerve injuries related to dental treatment: a retrospective study.

Objective: To provide a preliminary comparison of traditional clinical neurosensory examination (CNE) and current perception threshold (CPT).

Method And Materials: This is a retrospective chart audit of patients with trigeminal nerve injuries related to dental treatment who were evaluated with both CNE and CPT assessments (electrical stimulus tests) after presenting with altered sensation involving either the inferior alveolar nerve (IAN) or lingual nerve (LN) distributions. The tests were performed on the anterior two-thirds of the tongue for LN injuries and the lower lip and chin for IAN injuries.
