Neuropathic pain in the alveolar process of the mandible after pulpectomy treated with Keishikajutsubuto and Neurotropin^®

Abstract

I report a patient with neuropathic pain in the alveolar process of the mandible treated with Keishikajutsubuto and Neurotropin^®. A 36-year-old woman developed pain in the alveolar process of the mandible after pulpectomy of the right mandibular first molar tooth 2 years 7 months before. She was referred to our clinic because of prolonged pain. There was persistent ongoing pain and mechanical allodynia, which was provoked by light touch in the painful region. The patient was diagnosed as having neuropathic pain of the alveolar process of the mandible after injury to the inferior alveolar nerve. Keishikajutsubuto and Neurotropin^® were administered. Although slight uncomfortable sensation and paresthesia persisted in the gingiva, the pain disappeared 8 months after start of medication. Keishikajutsubuto and Neurotropin^® may be useful in some patients with neuropathic pain after pulpectomy.
