Quick answer: An OPG is a flat, panoramic X-ray of all the teeth and both jaws, useful as an overview. A CBCT (Cone Beam CT) is a 3D scan of a chosen area, used for exact measurements, such as for implants. At Ruprela, Raipur, a Digital OPG currently costs ₹600 and CBCT starts at ₹1,200.
Both tests use X-rays to look at your teeth and jaws, but they answer different questions. Think of an OPG as a wide photograph of your whole mouth, and a CBCT as a 3D model of one part of it that the dentist can turn and slice in any direction.
| Feature | Digital OPG | CBCT (Cone Beam CT) |
|---|---|---|
| Type of image | Two-dimensional panoramic picture | Three-dimensional scan |
| Area covered | All teeth, both jaws, jaw joints, lower sinuses | The area your dentist selects, from a few teeth to both jaws |
| Detail | Good overview; structures can overlap | Exact measurements in height, width and depth |
| Radiation | Low | Higher than an OPG, kept low by limiting the area |
| Typical uses | First check, wisdom teeth, braces planning, children's teeth | Implants, nerve position, impacted canines, complex root canals, cysts |
| Current price at Ruprela | ₹600 | Starts at ₹1,200 |
An OPG is often the first imaging test because it shows everything at once with a low dose. Your dentist may ask for an OPG:
In many cases, the OPG gives enough information, and nothing more is needed.
CBCT is used when a flat picture cannot answer the question safely. Typical situations include:
It is common for a dentist to start with an OPG to see the whole mouth, then ask for a CBCT of one area that needs more detail. For example, an OPG may show an impacted wisdom tooth, and a CBCT then shows exactly how close its roots are to the nerve. This step-by-step approach keeps radiation as low as reasonably possible while giving the dentist the information they need.
At Ruprela, CBCT is done on the Carestream CS 8200 Neo Edition and reported by Dr. Neha Patil (BDS, MDS – Oral). Both tests are available at the same centre, so if your dentist asks for both, you can usually plan them in a single visit.
No fasting is needed. Remove earrings, nose pins, necklaces, hairpins, spectacles and removable dentures before the scan. Bring your dentist's prescription, and tell the staff if you are pregnant or could be pregnant.

The choice of test should come from your dentist, who knows what information is needed. Please bring their prescription when you book.
