Mental nerve paresthesia associated with an amalgam filling: a case report.

We present a case report in which a mental nerve paresthesia occurred in connection with an amalgam filling placed in direct contact with the pulp of a mandibular first molar. The main evidence for amalgam being the dominant etiological factor was the positive epicutaneous patch testing response to the components of the amalgam alloy, and the total remission of symptoms without further clinical complications after removal of the amalgam filling and subsequent endodontic therapy.
