There are two primary forms of dental X-rays: intraoral (the X-ray film is within the mouth) and extraoral (the X-ray film is outside the mouth). The most prevalent type of X-rays are intraoral X-rays. There are numerous intraoral X-ray kinds. Each depicts distinct elements of teeth. Bitewing X-rays depict the upper and lower teeth in a single region of the mouth. Each bitewing displays a tooth from its crown (visible surface) to the level of its underlying bone. Bitewing X-rays detect cavities between teeth and changes in bone density caused by periodontal disease. Bitewing X-rays can also be used to check whether a crown (a cap that completely encircles a tooth) or other restorations fit properly (such as bridges). Additionally, it can detect any wear or degradation of dental fillings. Periapical X-rays depict the entire tooth, from the crown to the point where the tooth joins to the jaw, beyond the root. Each periapical X-ray image depicts all teeth in either the upper or lower jaw. X-rays of the periapical region detect any abnormalities in the root and surrounding bone structures. Occlusal X-rays monitor the development and positioning of a whole dental arch in the upper or lower jaw.   Extraoral X-rays are utilized to diagnose dental issues in the jaw and skull. There are a variety of extraoral X-rays available. On a single X-ray, panoramic X-rays depict the whole mouth, including all teeth in the upper and lower jaws. This X-ray reveals the position of completely erupted and erupting teeth, as well as impacted teeth, and aids in the identification of malignancies. Tomograms display one layer or “slice” of the mouth while blurring the other layers. This X-ray analyzes structures that are difficult to discern due to the presence of other neighboring structures. In cephalometric projections, the complete side of the head is displayed. This X-ray examines the teeth in relation to the individual’s jaw and profile. This X-ray is utilized by orthodontists to generate individualized tooth realignment strategies for each individual patient.
