Inhalation sedation - an adjunct to improved dental care: Preliminary communication

Abstract

This paper describes a double blind controlled comparison of 10% and 50% nitrous oxide in the sedation of children for dentistry. Both sedation groups compare favourably with a third group of unsedated children, in terms of heart rate changes occasioned by dentistry. However, 50% nitrous oxide was far superior to both 10% nitrous oxide and oxide and air when assessed by changes in the peripheral vasoconstrictive response to fear.
