Paresthesia of nerve due to acute apical periodontitis of a non-vital tooth: report of two cases

Paresthesia or dysesthesia of the inferior alveolar nerve (IAN) as the result of endodontic treatment or periodontal disease is a rare but serious occurrence. This paper describes two cases of paresthesia and dysesthesia of the IAN due to acute apical periodontitis of a right mandibular second molar and a right mandibular second premolar in proximity to inferior alveolar canal. Symptoms of sensory disruption disappeared approximately two months after conventional endodontic treatment associated with antibiotic therapy gives a good prognosis. Both teeth were asymptomatic during one year followup.
