What Is a Dental X-Ray, CBCT Scan and OPG?

Not all dental imaging is the same. Depending on your treatment needs, your dentist in Dubai may recommend one of three types of scan — each serving a different diagnostic purpose.

Digital dental X-rays (intraoral) show individual teeth or small groups of teeth in high detail. They are the most common imaging used in dentistry and are routinely taken during check-ups to catch cavities, check bone levels around teeth and assess the fit of crowns and fillings.

OPG (Orthopantomogram) panoramic X-rays capture the entire mouth — all teeth, upper and lower jaws, sinuses and the temporomandibular joints (TMJ) — in a single wide image. They are ideal for first-visit assessments, orthodontic planning and children’s dental development checks.

CBCT (Cone Beam Computed Tomography) is 3D dental imaging. A cone-shaped beam of X-rays rotates around the patient’s head to generate a full three-dimensional model of the jaw, teeth, nerves, sinuses and bone. CBCT is essential for dental implant planning, complex root canal cases and wisdom tooth removal.

When Does Your Dentist in Dubai Need to Take an X-Ray?

Dental imaging is not just for problems — it is a routine part of preventive care and treatment planning. Here are the most common situations where an X-ray or scan is needed:

• Before dental implants — CBCT confirms bone volume and precisely maps the nerve position
• Before root canal treatment — reveals how many canals are present, their curvature, and any periapical infection
• Before wisdom tooth extraction — shows proximity to the inferior alveolar nerve and the angle of impaction
• Orthodontic planning (braces or Invisalign) — OPG provides the full picture of tooth positions and jaw development
• Routine check-up — bitewing X-rays catch cavities between teeth and below the gumline that cannot be seen visually
• Gum disease monitoring — bone level X-rays track how periodontitis is progressing or responding to treatment
• TMJ jaw pain — CBCT shows the jaw joint in 3D to identify disc displacement, arthritis or fractures

Is Dental X-Ray Radiation Safe?

This is one of the most common questions patients ask — and the answer is reassuring. Modern digital dental X-ray equipment uses a very small dose of radiation, typically 0.005 mSv for a single bitewing X-ray. For context, you receive approximately 0.01 mSv of natural background radiation from the environment every single day.

At Top Smile Dental Clinic in Oud Metha, Dubai, our digital sensors reduce radiation exposure by up to 90% compared to traditional film-based X-rays. We follow ALARA (As Low As Reasonably Achievable) principles — meaning we only take X-rays when clinically necessary, and we always use protective lead aprons. Pregnant patients are always asked before any imaging.

CBCT vs OPG vs Regular X-Ray: Which Do You Need?

Dental X-Ray at Top Smile Dental Clinic — What to Expect

All dental imaging at Top Smile is performed in-house at our clinic in Oud Metha, Dubai — no referral to an external imaging centre is needed. This means faster treatment planning, same-day results and a more streamlined experience for you.

The process is simple: your dentist recommends the appropriate scan during your consultation, you spend 2–3 minutes preparing (removing jewellery, wearing a lead apron), the actual scan takes 10–40 seconds, and your dentist reviews the images with you immediately on the same visit.

Our digital imaging results are stored securely in your patient record. Files can be shared electronically with specialists, GPs or for second opinions on request.

Insurance Coverage for Dental X-Rays in Dubai

Routine diagnostic X-rays are covered by most UAE health insurance plans under preventive and diagnostic care. CBCT scans may require pre-authorisation from your insurer. Top Smile Dental Clinic accepts direct billing from MedNet, MetLife, Almadallah, NextCare and NAS Insurance — our insurance coordinator will verify your coverage before any imaging is performed so you know exactly what your out-of-pocket cost will be.
