Narcosis today is so common that one can not image what in former days surgery without narcosis ment to the surgeon and painwise to the patient. Just 160 years ago thingswhere completely different. Only few possibilities were on hand to ease the patients pain, when in 1842 the MD W. E. Clarke gave a ether narcosis to a patient while his associate, DDS Elijah Pope for the patient the first time painless removed a tooth. 1844 the patient Horace Wells received a painless tooth removal by his dentist Dr. John Riggs while his associate G. Q. Colton gave the patient nitrous oxide narcosis. 1846 the medical doctor Charles T. Jackson Morton proposed the use of pure ether for narcosis. Until the first local anestheticum was applied by injection by Einhorn (Procain ) in 1905 this was the only way to receive a dental treatment painless.
Nowadays the broad range of narcosis, reaching from sedation to intubation narcosis gives us the freedom to choose depending on the indication.
A dental nurse ( german: zahnmedizinischer Fachangestellter[ZFA]) is responsible to assist the practitioner while treatimg the patient and in questions of office organisation.
Some dental nurses are specialised in administration (Zahnmedizinische Verwaltungsassistentin, Zahnmedizinische Verwaltungsassistent). Their main topics are accounting, office management, law and economics, communication and rhetorics.
