title: Endodontic-related facial paresthesia: systematic review.
abstract: Paresthesia is a neurosensitivity disorder caused by injury to the neural tissue. It is characterized by a burning or twinging sensation or by partial loss of local sensitivity. Paresthesia related to endodontic treatment can occur because of extravasation of filling material or the intracanal dressing, as a consequence of periapical surgery or because of periapical infection. A literature review of paresthesia in endodontics was undertaken, with a view to identifying and discussing the most commonly affected nerves, the diagnostic process and the treatment options. Among reported cases, the most commonly affected nerves were those passing through the jaw: the inferior alveolar nerve, the mental nerve and the lingual nerve. To diagnose paresthesia, the endodontist must carry out a complete medical history, panoramic and periapical radiography, and (in some cases) computed tomography, as well as mechanoceptive and nociceptive tests. To date, no specific treatment for endodontic-related paresthesia has been described in the literature, since the problem may be related to a variety of causes.
