Selective anesthesias of peripheral branches of the trigeminal nerve due to odontogenic infection.

Infection of dental origin may induce anesthesias of peripheral branches of the trigeminal nerve and should be considered in the differential diagnosis of such neuropathies. This article presents two cases in which focal odontogenic infection caused sensory disruption at peripheral points along the maxillary and mandibular divisions of the trigeminal nerve. In both cases resolution of symptoms followed extraction of teeth responsible for the infection.
