Dental Assistant Practice Exam

Which component is part of the dental delivery system?

1. X-ray machine

2. Dental chair

3. Autoclave

4. Dental lab equipment

The correct answer is: Dental chair

The dental delivery system includes the components that aid in the clinical efficiency of providing dental care directly in the treatment area. The dental chair is a critical part of this system as it is designed to position the patient comfortably and appropriately for treatment, while also allowing access to the necessary instruments and equipment used by the dental procedure. This system typically includes elements such as the dental unit, which houses instruments and sometimes even dental lights and suction systems. In contrast, while the X-ray machine is essential for diagnostics, it is considered a separate piece of equipment that may not be integrated into the immediate delivery process of dental care. An autoclave, which is used for sterilizing instruments, functions outside of the treatment area, ensuring that tools are safe for use but is not involved directly in patient care. Likewise, dental lab equipment is utilized in a dental laboratory for fabricating prosthetics and custom devices, which is separate from the immediate delivery of care during patient appointments.
