Prognosis of a case with paresthesia associated with prolonged touching of an endodontic paste to the inferior alveolar nerve

subject

description

Paresthesia is described as an abnormal sensation, such as burning, pricking, tickling, tingling, formication or numbness. Several conditions can cause paresthesia. This article presents a case of paresthesia caused by the extrusion of endodontic paste (Endomethasone®) into the mandibular canal. The clinical manifestations comprised the numbness on the right side of the mandible and right lower lip, appearing after endodontic treatment. After a mandibular block and infiltration anesthesia a mucoperiostal flap was raised and the extruded Endomethasone® was removed successfully. A therapy with antibiotic, B vitamin complex and an analgesic were prescribed. The patient reported an improvement in pain and headache after one week later and in burning after two weeks. After a four months follow-up, she became symptom free. Also sixteen months later she had any symptoms. Normalization of sensation shows that the neurotoxic effects of Endomethasone® are reversible after more than one month from the first touch of Endomethasone® to the inferior alveolar nerve
