Instrument Setup consisting of a mouth mirror, an explorer, and cotton pliers. |
|
|
Bevel |
The slanted cutting edge on the blade of a hand instrument that is used to place a distinct beveled angle at the enamel margins of a cavity |
|
|
Carvers |
An instrument with sharp cutting edges used to shape tooth anatomy into restorations |
|
|
Contra-angle |
The angle at the head of the slow speed handpiece to which burs attach |
|
|
Dental Handpiece |
A mechanical device designed for use with rotary instruments. |
|
|
Fiber-optic system |
A system used with the high-speed handpiece that uses fiber optics to illuminate the oral cavity |
|
|
Fulcrum |
The pivotal point or support used to stabilize and control a dental instrument |
|
|
Straight Attachment |
The nose cone connection for the slow speed handpiece |
|
|
Assistant's Zone |
Positioning zone that is based on the clock concept. For a right-handed operator, the dental assistant is positioned in the zone of 2 to 4 o'clock; for a left-handed operator, the dental assistant is positioned in the zone of 8 to 10 o'clock |
|
|
Carpal tunnel syndrome (CTS) |
An injury associated with repetitive of continuous flexing and extending of the wrist |
|
|
Cumulative trauma disorder (CTD) |

|
Ergonomics |
The study and adaptation of how people work, including the anatomic and physiological characteristics of people in the work environment. |
|
|
Expanded Function Dental Assistant (EFDA) |
Dental Assistant who can perform certain intraoral procedures delegated by the dentist after the dental assistant has been specially trained in the expanded functions per the applicable state dental act |
|

The area above or behind the reclined patient. Based on the clock concept, that would be 12 to 2 o'clock for a right-handed operator and 10 to 12 o'clock for a left-handed operator. |
|
|
Transfer Zone |
The area through which materials and instruments are passed. This area is across the patient's chest. Based on the clock concept, for a right-handed operator this would be in the zone of 4 to 7 o'clock and for a left-handed operator in the zone of 5 to 8 o'clock. |
