electronic dental anesthesia


electronic dental anesthesia

Abbreviation: EDA
In dentistry, the use of low levels of electric current to block pain signals en route to the brain. The patient controls the current through a handheld control. The current creates no discomfort and, unlike local anesthesia, leaves no numbness to wear off once the dental work is completed. See: audioanalgesia; patient-controlled analgesiaSee also: anesthesia
