Medical imaging has been revolutionizing the medical world for decades now—and dentistry is no exception. Traditional x-rays on film have been gradually replaced by digital x-rays.

Why are x-rays needed?

Digital x-rays are an essential diagnostic tool used along with a visual examination. They help detect anomalies that would otherwise be invisible to the naked eye, for quick, preventive action.

In general, x-rays are taken during a regular dental check-up. There are four types:

• Bite-wing
• Periapical (one tooth, from root to crown)
• Panoramic (a panorex shows the entire dental structure)
• Cephalometric (neuromuscular and orthodontic treatments)

Advantages:

• Minimal exposure to radiation
• Safe, quick and comfortable
• High quality images and better contrast for improved sharpness
• Images are saved in the patient’s electronic file
• Easy to share with other health professionals or insurance company
• Small environmental footprint

What x-rays detect

Digital x-rays can show anomalies and disease under the gums, on the alveolar bone or on the root, such as:

• Interdental cavity
• Dental malposition
• Bone loss
• Cyst or abscess
• Lesion (cancerous or non-cancerous)
• Developmental anomaly
