(right-handed—7 o'clock to 12 o'clock; left-handed—12 o'clock to 5 o'clock
Operator's Zone
the dentist must be in the same treatment area as the EFDA/RDA for the assistant to perform the function.
Direct supervision
temporary loss of feeling or sensation with the use of a drug
anesthesia
Makes the solution isotonic with body tissues
Short acting anesthetic
process by which the operator and the assistant work together to perform clinical procedures in an ergonomically structured environment
4 - handed dentistry
(right-handed—4 o'clock to 7 o'clock; left-handed—5 o'clock to 8 o'clock)
Transfer zone
the dentist must be in the dental office area but not necessarily present in the same treatment room as the EFDA/RDA;
indirect supervision
standard thickness, size, or measurement of something, such as the thickness of an injection needle
gauge
Bleeding at the injected area is decreased, which is especially important for surgical procedures when you use a

Vasoconstrictor
often referred to as mandibular nerve block
Inferior alveolar nerve block AKA "IA"
are based on a “clock concept” and describe the best way to identify the working position of the dental team, the dental equipment, and the supplies needed to perform a procedure. This basic concept is used in the practice of efficient and comfortable clinical dentistry and can be applied to any dental procedure.
