A cleaner look at cavities: does polishing or bleaching skew detection?
NCT ID NCT07763470
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This trial asks whether two common cleaning methods—mechanical polishing with a paste or applying a 35% hydrogen peroxide gel—change the readings of a laser device (DIAGNOdent) used to spot early tooth decay on the chewing surfaces of back teeth. In each participant, one side of the mouth gets one cleaning method and the other side gets the other, allowing a direct comparison. The goal is to see if either method alters the device's scores, which could help dentists interpret readings more accurately when teeth are stained.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Mechanical polishing with fluoride-free prophylaxis paste or 35% hydrogen peroxide gel applied to stained tooth fissures before laser fluorescence measurement.
- What this could lead to
- If successful, this could help dentists get more accurate cavity detection readings on stained teeth, reducing false alarms and improving treatment decisions.
- What could go wrong
- This is a small, early-stage study (25 participants) measuring device readings, not actual decay outcomes. Results may not apply to all patients or staining types, and the cleaning methods themselves are not treatments.
