HOSA Dental Terminology Practice

The term "biteblock" is used to describe which dental tool?

1. A tool for measuring bite force

2. A device used to stabilize a patient's jaw

3. A device used to hold radiation film in the mouth for exposure

4. A type of dental impression tray

The correct answer is: A device used to hold radiation film in the mouth for exposure

The term "biteblock" refers specifically to a device used to hold radiation film in the mouth for exposure. This tool is crucial in dental radiography, as it helps position the film accurately within the oral cavity during X-ray procedures. The biteblock allows for the correct angling of the X-ray beam, ensuring that images are captured clearly while minimizing patient discomfort. Understanding the function of a biteblock is essential in dental imaging. It supports both the film and the patient’s jaw, which is particularly important in obtaining quality radiographs. This positioning helps to achieve the desired diagnostic outcome while adhering to safety protocols in radiation exposure. While there are devices for measuring bite force and tools that stabilize a patient’s jaw, those do not specifically fit the definition of a "biteblock." Likewise, although dental impression trays serve an important role in capturing the shape of teeth and gums, they are designed for a different purpose entirely and are not used for radiographic film placement.
