Evaluation of early nerve regeneration using a polymeric membrane functionalized with nerve growth factor (NGF) after a crush lesion of the rat mental nerve.

Purpose: The aim of this study was to evaluate mental nerve regeneration in rats after a crush lesion by using a polymeric membrane functionalized with nerve growth factor (NGF).

Materials And Methods: To evaluate the regeneration 1 month after the lesion, electrophysiological recordings of afferent neurograms were associated with a histologic analysis of neurons soma in the trigeminal ganglion using a retrograde fluorescent tracer. Three animal groups were used: uninjured rats (TEM), injured control rats without membrane (CONT), and injured rats with membrane containing NGF.

Neurosensory disturbances of the inferior alveolar nerve: a retrospective study of complaints in a 10-year period.

Purpose: The aim of this study was to evaluate the prevalence of neurosensory disturbances (NSDs) of the inferior alveolar nerve after dental procedures.

Materials And Methods: A retrospective study of patient complaints for transient and permanent NSDs was achieved by means of a 10-year follow-up of claims to a national practitioner insurance company. Claims for 3 different dental procedures were analyzed from 157,292 contracts of insurance recorded during this period.
