Shining a light on tooth spots: new pretreatment may boost aesthetic results
NCT ID NCT07753070
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This trial tests whether a special light-guided pretreatment can improve the cosmetic outcome of resin infiltration for teeth affected by molar incisor hypomineralization (MIH), a condition causing white or creamy spots on permanent incisors. The study compares two approaches: one where the tooth surface is roughened and then treated with a bleaching agent, versus roughening alone. The goal is to see if the added step improves the masking of the spots and reduces the time needed for the resin treatment. The trial involves 100 healthy children with mild MIH-related opacities on their front teeth.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- macroabrasion followed by oxidative pretreatment with 5.25% sodium hypochlorite, compared to macroabrasion alone
- What this could lead to
- If effective, this approach could improve the cosmetic appearance of teeth affected by MIH and shorten the time needed for resin infiltration treatment.
- What could go wrong
- This is a small, early-stage trial, and results may not apply to all cases. The pretreatment involves chemicals and abrasion, which carry risks of tooth sensitivity or gum irritation.
