What is dental radiography?
Dental radiographs, also referred to as X-rays, are radiographs used to identify cavities, bone loss, benign or malignant tumors, and hidden dental structures.
A radiographic image is created by a controlled burst of X-ray radiation that, depending on the anatomical densities, enters oral structures at various depths before impacting the film or sensor. Because less radiation passes through teeth to the film, they seem lighter. The periodontal ligament, dental cavities, infections, and other changes in bone density all seem darker because X-rays can easily penetrate these less thick tissues. Depending on the material's density, dental restorations (fillings, crowns) may appear lighter or darker.
