Dental X-rays are a vital part of a dental examination There are two main types of dental X-rays: those taken with the X-ray film inside the mouth (intraoral) and those taken with the X-ray film outside the mouth (extraoral). Intraoral X-rays are the ones most commonly used. They provide detailed evidence of the growth of developing teeth, the health of tooth roots and surrounding bone, including the jaw. They also help the dentist zero in on any cavities. Extraoral X-rays, while they also show the teeth, primarily focus on the jaw and skull. They are therefore more helpful in diagnosing malocclusions, impacted teeth, and possible temporomandibular joint disorders (TMD).
Radiology is an important tool in diagnosing and assessing dental abnormalities in patients. It is especially helpful in treating patients with problems in the dentomaxillofacial region. Cone Beam CT Scan Imaging, also known as CBCT, is considered an important innovation in dental X-ray diagnostics, particularly for dentomaxillofacial surgery. Unlike regular X-rays, CBCT scans can differentiate among many types of tissue including bone, teeth and nerves.
