Paresthesia of the mental nerve induced by periapical infection: a case report

Paresthesia can be a rare complication of infections of dental origin. This article presents a case of anesthesia/paresthesia caused by a periapical infection of the right mandibular second premolar. The sensory disturbance disappeared 2 weeks after conventional endodontic treatment associated with antibiotic therapy. Twelve months later, the tooth was still asymptomatic. The possible mechanisms responsible for paresthesia associated with periapical infection are discussed.
