Battle of the bright smiles: which technique best hides MIH white spots?
NCT ID NCT07715370
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This trial tests three different surface treatments—microabrasion, etch-bleach, and macroabrasion—before applying a resin infiltration procedure to improve the appearance of white spots on permanent front teeth in children aged 8 to 14 with molar incisor hypomineralization (MIH). The goal is to find the most effective, conservative approach to reduce these enamel opacities and improve the child's quality of life. Researchers will measure color change and use a questionnaire to assess how the treatment affects the child's well-being.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- resin infiltration, microabrasion, and etch-bleach procedures
- What this could lead to
- If successful, this could identify the best minimally invasive technique to improve the look of white spots on front teeth in children with MIH, boosting their confidence.
- What could go wrong
- This is a small, early-stage trial with only 63 participants, so results may not apply to everyone. The procedures may not fully mask the spots or could cause tooth sensitivity.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Cooperative healthy male and female children aged 8 to 14 years. * MIH diagnosed patients according to the criteria of European Academy of Pediatric Dentistry (EAPD) with demarcated enamel opacity that caused esthetic discomfort to them and their guardian, involving at least one maxillary or mandibular permanent incisor. * At least one-third of the affected tooth crown should be visible in the oral cavity. Exclusion Criteria: * Children with behavioral, cognitive, physical, or medical conditions that will affect or complicate the treatment. * Other developmental defects of dental enamel rather than MIH (i.e. dental fluorosis, enamel hypoplasia, amelogenesis imperfecta or Turner's tooth) * Loss of tooth structure due to post-eruptive enamel breakdown or caries. * Periodontal disease of the affected tooth. * Incisors previously subjected to trauma that might lead to loss of tooth structure or compromise the pulp vitality. * Previous preventive, restorative or orthodontic treatment on the affected tooth.
