Who determines the number, type, and frequency of dental x-rays based on individual patient needs?

The dentist is the primary professional responsible for determining the number, type, and frequency of dental x-rays based on the individual needs of each patient. This decision is guided by the dentist's clinical judgment, which takes into account several factors such as the patient’s dental and medical history, current oral health status, age, risk factors for dental disease, and any specific concerns that may require imaging.

The dentist has the training and expertise necessary to interpret diagnostic images and understand the implications of findings, allowing them to make informed decisions regarding the necessity of radiographs. They aim to ensure that the patient receives the appropriate level of care while minimizing unnecessary exposure to radiation.

While dental assistants and hygienists may play important roles in carrying out radiographic procedures and maintaining patient safety during imaging, the ultimate responsibility for determining when and what type of x-rays are needed resides with the dentist. Insurance companies typically do not influence clinical decision-making on the appropriateness of x-rays; rather, they have policies that may affect reimbursement for provided services.
