What type of dental imaging technique utilizes radiation to obtain images of the teeth and surrounding structures?

The dental x-ray is a specific imaging technique that employs ionizing radiation to create detailed images of the teeth, gums, and supporting bone structure. This method allows dental professionals to identify issues such as cavities, bone loss, and impacted teeth that may not be visible during a regular dental examination.

Dental x-rays come in various forms, including periapical, bitewing, and panoramic images, each serving different diagnostic purposes. By utilizing a controlled amount of radiation, dental x-rays are considered an essential part of dental practices, enabling accurate assessments and treatment planning. This imaging is crucial not only for preventive measures but also for diagnosing various dental conditions effectively.

In comparison, other imaging techniques mentioned, such as ultrasound, CT scans, and MRI, either use different forms of energy or are typically employed for other medical purposes and are not standard in routine dental diagnostics.
