The combined effect of nitrous oxide and oxygen and electrical stimulation during restorative dental treatment



D Donaldson, F Quarnstrom, and JT Jastak
Department of Medical and Surgical Sciences, Faculty of Dentistry, University of British Columbia, Vancouver, Canada.

A total of 124 adult patients were treated with nitrous oxide (N2O) and oxygen (O2), an electrical analgesic, or a combination of N2O/O2 and an electrical analgesic during restorative dental procedures. The use of electrical analgesic or N2O/O2 without local anesthetics resulted in a high failure rate and poor patient acceptance. However, combining N2O/O2 sedation with electrically induced analgesia resulted in a statistically significant improvement over either technique used alone, and provided an overall 81% success rate when used during restorative dentistry.
