May 5, 2011 — The root cause of local anesthetic-related neurosensory disturbances (NSDs) in dentistry has been unclear. But now a group of Danish researchers say it is neurotoxicity related to high-concentration formulations of anesthetics — particularly articaine — not needle penetration (Journal of the American Dental Association, May 2011, Vol. 142:5,pp. 531-540).
