AUXILIARIES
⁕ Socrates, in defining the ideal state, gives as a
prerequisite that men should divide the labor, certain
men becoming expert in certain fields, others in other
fields, and all working as a team for the common
good.
⁕ Some task actually require more than two hands
⁕ Other tasks are more quickly or better performed if
one worker confines himself to part of the task,
leaving other parts to other workers.
⁕ A final reason lies in the different levels of
knowledge attainable within one field by opportunity
for training.
Reasons for division of Labour
⁕ Certain parts of task require top-level skill and knowledge. In
dentistry these are the so called “professional services.”
⁕ Other parts of the task require less skill and knowledge.
These may safely be delegated to auxiliary personnel.
⁕ Society benefits from this sort division of labour in that
training time for professional personnel can be conserved.
⁕ Since large tasks, and particularly community-wide tasks, are
those where division of labour and teamwork are most
needed.
DENTAL AUXILIARY
⁕ Dental auxiliary is a person who is given responsibility by a
dentist so that he or she can help the dentist render dental
care, but who is not himself or herself qualified with a dental
degree.
⁕ The duties undertaken by dental auxiliaries range from
simple tasks such as sorting instruments to relatively
complex procedures which form part of the treatment of

2. Indirect supervision: The dentist diagnoses and plans
the treatment but he authorizes the auxiliary to carry out the
treatment in the field (eg. school premises) while the dentist
remains in the dental office.
3. Direct supervision: Similar to general supervision, the
dentist diagnoses and plans the treatment of a patient and
authorizes the auxiliary to carry out the treatment but before
the dismissal of the patient, the dentist evaluates the
procedure performed by the auxiliary.
4. Personal supervision: The dentist himself performs
the treatment but authorizes the auxiliary to provide
supportive assistance.
• With rapid population growth and increase demand for dental
care more and more dentists are required but this is an
expensive process.
• Training of auxiliary is more economical, less time consuming
and fewer burdens to the society.
• More oral health services to the community-more improvement.
• More productivity of dental care services.
• Better coverage of Preventive Services to individual patients
and groups.
Benefits of using Auxiliaries

⁕ India needs a longer positive approach in creating and
expanding dental auxiliaries systems to meet the demands.
⁕ The dental auxiliary present in India are dental hygienist,
laboratory technician and dental surgery assistants, which have
been recognized by Ministry of Health; Government of India
and certificate courses recognized by Dental Council of India.
