What type of radiation is primarily used in dental radiography?

In dental radiography, the primary type of radiation used is X-rays. X-rays are a form of electromagnetic radiation that can penetrate various materials, including human tissue, which makes them particularly effective for imaging purposes. In dentistry, they help in diagnosing conditions, identifying cavities, assessing the health of bone structures, and planning treatments.

The energy produced by X-rays allows for the capture of detailed images of the teeth and surrounding tissues on radiographic film or digital detectors. Their wavelength and energy level are specifically suited for the penetration required in dental imaging, which is why they are the preferred choice in this field.

Other forms of radiation listed in the options, such as gamma rays, ultraviolet rays, or infrared rays, do not have the same properties that make X-rays suitable for dental imaging. Gamma rays, while similar to X-rays, are typically generated by radioactive materials and are used more in nuclear medicine than in standard dental practices. Ultraviolet rays and infrared rays have entirely different applications and do not possess the necessary penetrative ability for producing clear diagnostic images of dental structures. Thus, X-rays are the standard and most effective form of radiation employed in dental radiography.
