Patient In New Dental Chair Controls Drill and Gas (Oct, 1935)
Patient In New Dental Chair Controls Drill and Gas
THE patient is king in a new painless dentistry chair now in use in a Chicago dentist’s office. When drilling becomes excessively painful the patient, by means of a button held in the left hand can turn off the drill. If the patient prefers to have the work continue, but wishes to eliminate the pain, he or she can press a bulb held in the right and administer a dose of pain killing gas.
Dentists find the devices are successful not only in actual operation, but in the psychological effect they have on the patients. The knowledge that they can stop the drill at any time reduces the nervous tension.
