Can a glowing dye reveal hidden tooth decay?

NCT ID NCT04748913

First seen Aug 07, 2026 · Last updated Aug 07, 2026

Summary

This study tests whether a special light-based scanner, called DIAGNOcam, can better detect early cavities between teeth when used with a dye. Researchers will compare this method to standard X-rays and a visual-tactile exam. The goal is to see if the dye improves the ability to tell whether a cavity has formed a hole (cavitation), which helps decide the best treatment.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Near-infrared transillumination with indocyanine green dye (DIAGNOcam)
What this could lead to
If successful, this could lead to more accurate, less invasive detection of early cavities, potentially reducing the need for fillings.
What could go wrong
The dye may not improve detection enough to be clinically useful, and the study is relatively small, so results may not apply broadly.
