A general account has been given of experience in over 500 dental operations in which the ultra short acting barbiturate sodium pentothal has been used. Types of cases selected for dental operations under intravenous anaesthetic have been descriptionbed. Dosage and points in the technique of administration have been mentioned. Results justify the conclusion that in Sodium pentothal we have a most useful additional anaesthetic agent for dental use which produces anaesthesia of short duration, easy and pleasant induction, smooth maintenance, rapid uneventful recovery without complications, and safe in experienced hands under conditions where there is ready access to oxygen, preferably delivered under pressure from an anaesthetic machine, and ready availabilIty of laryngoscope.
