Understanding how ionizing radiation affects living tissues is central to radiation biology in dental radiology. This field explores the mechanisms by which radiation causes cellular and molecular injury, how tissues respond—whether they repair, adapt, or undergo cell death—and how radiosensitivity varies among different tissues. It also encompasses the overall radiation risk to patients, guiding safe imaging practices and dose optimization. In dentistry, this knowledge helps anticipate effects on the pulp, mucosa, salivary tissues, and bone, and informs decisions that minimize harm while obtaining diagnostic-quality images. The other topics focus on imaging technology or image appearance—detector specifications, image density and contrast, or film speed and processing—which impact image quality or workflow but do not address how radiation interacts with biological tissue or the associated risks.
