Final answer:
In dental radiography, the DA/DH is mainly responsible for assisting in procedures, maintaining patient safety through shielding and positioning, and keeping track of radiographic databases. They help in diagnostic preparations and ensure adherence to radiation protection guidelines.
Step-by-step explanation:
The role of a Dental Assistant (DA) or Dental Hygienist (DH) in dental radiography primarily involves assisting dentists in dental radiography procedures. They are responsible for several critical tasks including preparing patients for exams, ensuring proper positioning, and maintaining safety protocols through the use of shielding, increasing the distance from the source, and minimizing exposure time. DA/DH may also help in maintaining databases of radiographs as part of their record-keeping duties. While they may not typically develop algorithms for image processing, their work supports the use of technology in diagnosing and treating patients.
Training for radiography technicians can be obtained at hospitals, colleges, and universities, and involves learning to manage radiography equipment, as well as safety and protection measures to minimize radiation doses to patients and operators.
