Endodontic periapical lesion-induced mental nerve paresthesia

Elham Shadmehr, Neda Shekarchizade


Paresthesia is a burning or prickling sensation or partial numbness, resulting from neural injury. The

symptoms can vary from mild neurosensory dysfunction to total loss of sensation in the innervated

area. Only a few cases have described apical periodontitis to be the etiological factor of impaired

sensation in the area innervated by the inferior alveolar and mental nerves. The aim of the present

paper is to report a case of periapical lesion-induced paresthesia in the innervation area of the

mental nerve, which was successfully treated with endodontic retreatment.

Key Words: Apical periodontitis, endodontic therapy, inferior alveolar nerve, paresthesia
