Parestesias

: etiologia e abordagem clínica

Abstract

Alterations from normal oral sensory function can occur by numerous factors such as surgical and restorative dental procedures. These sensory alterations, generally called paresthesias, can range from a slight until complete loss of sensory function, and can become mutilating to the patient. Most of paresthesias resolves within days, weeks or months. Paresthesias that last beyond 6 to 9 months can be described as persistent. Paresthesias can relate to, for example, oral surgery by removing mandibular third molars and pre-molars and/or removal of cysts, implants, endodontic treatment, orthodontic treatment, dentistry, solutions and anesthetic techniques ... Cases documented in the literature report that the majority of the paresthesias is caused in lingual nerve and inferior alveolar nerve that was mostly associated with surgical procedures. The paresthesia status may reverse spontaneously, but when this isn’t possible, there therapeutic modalities that can be adopted, such as, nerve affected decompression, microsurgical repair of traumatic injury of the nerve, make use of anti-neuritic, anti-inflammatory, use of low level laser or acupunture. It must be considered that the best way to prevent paresthesia is the realization of a careful planning pretreatment of any clinical case. The Dentist should take all preventive measures in order to prevent such complications. It is intended perform a bibliographic review about the pathogenesis of paresthesias, its clinical and appropriate therapeutic approach
