Possible cases of dental treatment-associated death under local anesthesia in Japan: A review of the literature

Unexpected dental treatment-associated deaths under LA were reported. It may be difficult to predict these adverse events before treatment from patient records. This study warns that severe adverse events or mortality are possible even during outpatient dental treatment with use of LA alone. A dentist is required to manage these situations. Also, mortality cases must be avoided with maximal reliability on the dentist.
