century .
The first dental assistant was hired in 1885
by Dr C. Edmund Kells of New Orleans.

that female patients could respectably come to his
office.
Dental assistants continued to serve as office
helpers until World War II, when there was a
crucial shortage of labor to meet dental care
demands of dental service.
Thus in the armed forces, assistants were trained
to work at chair side in an attempt to increase
productivity.

treatment of dental caries & periodontal disease in
defined groups of people, usually school children.

31. BACKGROUND
The dental nurse scheme was established in
Wellington, New Zealand in 1921.
This was due to the extensive dental disease found
in army recruits during world war I [1914-1916].
The man who influenced its formation was T.A
Hunter, a founder of New Zealand dental
association & a pioneer in the establishment of
dental school in New Zealand.

32. The stimuli for the program were the
extensive dental disease found in army
recruits during World War I & government
intended to do something about this problem.
Dentists were in short supply at that time &
treatment of young children was not as
accepted in dental practice as it is now.

33. When the service began care was offered only
to younger school-aged children. But eligibility
now extends to all pre-school aged children &
all children in primary & intermediate school [2
1/2 – 13 1/2 years of age].
In Britain the 1st operating auxiliaries based on
New Zealand school dental nurse model
graduated in 1962.

34. They were generally known as ‘New Cross’
auxiliaries, because the training school is located
in New Cross area of south London.
In Saskatchewan a Canadian province & only
place in North America where someone other than
a dentist may legally drill & fill the teeth, the
nurses receive direct supervision during 1st 2
months & then work with a more experienced
dental nurses for the 3rd month.
If their performance is found to be satisfactory,
then they work without direct supervision.

of dental nurses.
After the successful completion, they are taken
into government services as
Full-time dental nurses in the school system.

38. Each dental nurse then becomes responsible for
approximately 500 children for whom she is
expected to provide dental care at 6 month
interval.

39. SUPERVISION OF NEW ZEALAND DENTAL NURSE
The work of dental nurse is performed under the
general supervision of a district principal dental
officer, who delegates certain of his

clinic perhaps once every 6 weeks, the dental nurse
inspector twice as often.

40. NEW TRAINING SCHOOLS FOR DENTAL NURSES

attracted the attention of dental organization all
over the world.

similar programs, with modification to suit the
local environment, include Canada, Britain,
