Neuropathic orofacial pain (NOP) is initiated or caused by a priomary lesion or dysfunction in the peripheral nervous system or the central nervous system. NOP is divided into paroxysmal and continuous by duration of pain. NOP is important for dentists, because they can occur after dental procedures, such as extractions, endodontic treatment, and dental implant insertion. Dentists should have concern about NOP, because it is difficult to diagnose and treat.
