## Q-ray Diagnosis

Q-RAY FLUORESCENCE CHECK

## Q-ray Diagnosis*explained*

**Blue light** is shone on the teeth to show, in colour, **early decay, plaque and tartar** that are hard to see with the eye.

1. **An exam with light**It uses 405nm blue light, so no radiation is involved.
2. **See it on screen together**We look at the images together on the screen in the treatment room.
3. **Compare over time**The same area can be scanned again at the next check-up to compare changes.

At MEGAPLANT Seodaemun we use the AIOBIO Qscan device.

HOW TO READ

### How to read the colours on screen

Healthy teeth and problem areas show up in **different colours**.

**Green** — healthy tooth. It glows green under blue light.

**Red** — plaque or tartar with many bacteria, or active decay. It shows where the toothbrush is not reaching.

**Dark areas** — places where weakened enamel suggests early decay (demineralisation).

COMPARE

### How it differs from a visual exam and X-ray

|  | Visual exam | X-ray | Q-ray |
| --- | --- | --- | --- |
| Radiation | None | A small dose is used | None (blue light) |
| Good at showing | Visible decay and discolouration | Inner structures: between teeth, roots, jawbone | Early surface decay, plaque, tartar |
| Limits | Early changes are easily missed | Early surface changes are hard to see | Cannot show deep decay or bone |

※ Q-ray does not replace X-rays. We read it **together with a visual exam and X-rays** to reach a diagnosis.
