Abstract
Third molar extraction, one of the important surgical treatments commonly practiced in dentistry, presents various symptoms after surgery ranging from temporary or mild symptoms to permanent or severe complications. However, oral burning pain, dysesthesia, parageusia, dry mouth, headache and pain in multiple teeth are not the common symptoms that patients often complain after dental extraction. Here, the authors report two cases who presented acute neuropathic symptoms mentioned above in the orofacial regions following third molar extraction. At the initial examination, the healing of the tooth sockets of two patients was normal. One patient was diagnosed as megaloblastic anemia associated with Vitamin B12 deficiency and was referred to the Department of Hematology for assessing the underlying etiology of anemia. The laboratory test for the other patient revealed microcytic anemia related to iron deficiency. The patient with iron deficiency anemia was successfully treated with iron supplement. These two cases suggest that anemia, as an underlying systemic disease, may be a rare etiology explaining acute onset of peripheral neuropathy in the orofacial regions after third molar extraction and should be considered in the assessment of patients who report neuropathic symptoms after dental extraction.
