Four handed Dentistry

# When utilizing four-handed dentistry, the assistant should be positioned...
A. Higher than the dentist to facilitate visibility
B. Different positions depending on where the dentist is working
C. Lower than the dentist for ergonomic posturing
D. At the same height because they are a team


The correct answer is A. Higher than the dentist to facilitate visibility.

In four handed dentistry, the assistant
should sit close to the back of patient's
chair higher than the dentist to facilitate
visibility.

This position is suitable for better view of
the site, instruments and materials from the
mobile cart or instrument tray. It also allows you access to these materials without leaning or overextending your arms.

Assistant stools should be placed in a
position so that their eye level is 4 to 6
inches higher than the dentist's.
