Ace the 2025 DANB RHS Challenge – Radiate Confidence in Your Dental Journey!

The function of filtration in dental radiography is to filter out low-energy X-rays. These low-energy X-rays do not contribute to the formation of an image but do increase the patient's radiation dose without providing any diagnostic benefit. By using filtration, which typically involves inserting a material such as aluminum in the X-ray beam path, the X-ray machine is able to allow only the higher-energy, more penetrating X-rays to pass through to the patient. This enhances safety by reducing unnecessary exposure while still producing a high-quality diagnostic image. In turn, this practice contributes to the overall goal of minimizing radiation exposure to patients while ensuring the effectiveness of the imaging process.
