What characteristic is NOT part of the Dental Assistant Delivery System?

The characteristic that is not part of the Dental Assistant Delivery System is a portable x-ray machine. The Dental Assistant Delivery System is designed to streamline the process of dental procedures, providing tools and equipment that are easily accessible and efficiently integrated into the treatment area.

A high-volume evacuator tip, self-contained water unit, and bracket table are all integral components of this system. The high-volume evacuator is used to maintain a clear field of vision by immediately removing excess fluids from the patient's mouth. The self-contained water unit provides a source of water for rinsing and other functions directly from the dental delivery system, which enhances productivity and hygiene. The bracket table organizes and supports the instruments the dentist needs, facilitating smooth workflow during procedures.

In contrast, a portable x-ray machine, while useful in certain settings, is not a component of the standard delivery system utilized by dental assistants in most clinical environments. It is typically an additional tool that can be used in specific situations rather than a core part of the setup that assists directly in major dental procedures during routine care.
