Abstract

Introduction

Foreign bodies' entrapments in the mandibular and submandibular regions are quite common.

Case presentation

We report an unusual case of foreign body (amalgam filling) entrapment over the mental foramen causing dysaesthesia in the distribution of the mental nerve. An interesting sign was blue discoloration of the overlaying oral mucosa which was interpreted as amalgam tattooing.

Conclusion

Surgical removal of the foreign object eliminated the reported symptoms.
