Digital X-Rays

Today, the evolution of dentistry with latest technologies is gaining importance as a safe, reliable and a comfortable solution for both, the dentist and the patient.

X-rays, also known as radiographs are powerful diagnostic tools. They are an essential part of any dental care treatment plan. They are also used for preventive care. X-rays help the dentist to evaluate and compare the normal structures, diagnose potential risks in the oral cavity and detect dental problems in early stages, before they become a major concern.

X-rays allow dentists to:

  • Detect cavities, gum diseases and infections
  • Identify the anomalies of the roots and its surrounding structures
  • Study the positions of wisdom teeth
  • Review the jaw structure and teeth before an orthodontic therapy is applied
  • Assess bone density before dental implant treatment
  • Determine the depth and extent of cysts and tumours of teeth and jaws
  • Evaluate the fractures of teeth and jaws and see the tooth root
  • Diagnose salivary gland disorders
  • Visualize the hidden abnormalities of teeth and jaws.

Digital x-rays or digital radiography is the latest concept of X-ray imaging where sensors are used instead of traditional x-ray films. The x-ray sensors are connected to the computer through which the x-ray image can be viewed instantly.

Types of X-rays:

X-rays are of two types, depending on where the X-Ray sensor is placed: intraoral (inside the mouth) and extraoral (outside the mouth). Intraoral X-rays are the most common type of radiograph in dentistry which provide a high level of detail of the tooth, bone and supporting tissues of the mouth.

  1. Intra oral and extra-oral X-rays are further classified based on their specific purpose of use, such as:


Intra-oral X-Rays:The sensors are placed inside the mouth to detect the abnormalities of individual teeth in detail. They are small and can cover 3-4 teeth at a time. They are of two types:

    • Periapical X-Rays: They are used to detect the abnormalities of tooth crown, root and its surrounding structures. Tooth decay, peri-apical and periodontal abnormalities, position of wisdom teeth can be assessed with this type of X-rays.
    • Bite Wing X-Rays: They are used to detect the abnormalities of the structures between the crowns of teeth above the roots and gums.

Extra-oral X-Rays:They are used to detect extensive abnormalities of teeth, jaws and joints. These radiographs are also used to monitor the growth and development of jaws, temporomandibular joints (jaw joint) and facial bone.</p

    • Panoramic X-rays: These x-rays help to visualize both upper and lower jaws in a single image. They are advised for diagnosis of cysts and tumours of teeth and jaws, for evaluation of the jaws before starting orthodontic therapy; and in the diagnosis and treatment of fractures of jaw bones or facial bones.
    • Cephalometric X-rays: These X-rays are used to assess the jaw profiles before commencing an orthodontic therapy.
    • Cone beam computerised tomography (CBCT): These advanced digital x-rays help to visualize internal structures of the body in a three-dimensional view. CBCT is advised before planning for complex dental procedures such as dental implants, surgical removal of impacted teeth or fractured teeth, complicated anatomy of root canals in molars, deep-seated lesions of jaws etc.

Benefits of Digital X-rays:

  • Low radiation exposure: Digital x-rays require less than 90% of radiation compared to traditional x-rays for the same image quality. Digital x-rays are safer for those coditions that require regular monitoring with dental x-rays.
  • High quality images: The image quality of digital x-rays is better as the x-ray images can be magnified, increase brightness, colour, contrast and sharpness for better understanding and diagnosis of dental problems. Digital radiography combined with additional software programs enable dentists to detect even the minor defects of teeth.
  • Short dental appointments: Digital x-ray images are instantly projected on the computer screen making dental appointments shorter. Whereas, the traditional method additionally requires x-ray development that takes more time and delay the process.
  • Accessibility: Digital images are convenient to transfer from patients to dentist through email.
  • Patient Records: Pre-treatment digital x-rays are usually preserved as part of the patient records in your dentist’s office and can be retrieved when needed, to get a second opinion or a consultation from a dental specialist.
  • Eco-friendly: Digital x-rays are eco-friendly, since these x-rays are not film-based, they do not require liquid chemicals like developers and fixers.
