The document discusses the roles and classifications of dental auxiliaries. It notes that dental auxiliaries assist dentists and take on tasks that require less skill, helping to improve access to dental care. Dental auxiliaries discussed include dental assistants, hygienists, technicians, and other roles with varying levels of training and supervision. The use of auxiliaries benefits communities by improving coverage of preventive services and increasing the productivity and efficiency of dental care delivery.
3. ⁕ 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.
4. ⁕ 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
5. ⁕ 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.
