Hydroxyapatite home treatment for sensitive teeth in people with celiac disease

Reduction of Dentin Hypersensitivity and Enamel Demineralization in Patients With Celiac Disease: A Randomized Controlled Trial

Not applicable Interventional University of Pavia · NCT07069127

The trial will see if adding a nightly hydroxyapatite mousse to regular hydroxyapatite toothpaste reduces tooth sensitivity in adults with celiac disease and enamel demineralization.

What this trial studies

This single-center, randomized controlled trial will enroll 40 adults with confirmed celiac disease who have enamel demineralization, active caries, and self-reported dentin hypersensitivity. Participants are randomized into two parallel groups: one using hydroxyapatite toothpaste twice daily, and the other using the same toothpaste plus a nightly hydroxyapatite mousse for the study period. The primary outcome is change in dentin hypersensitivity measured by the Schiff Air Index; secondary outcomes include plaque index, bleeding on probing, pain on a visual analogue scale, and caries experience (DMFT/DMFS). All products are applied at home with scheduled clinic visits at the University of Pavia for baseline and follow-up assessments.

Who should consider this trial

Good fit: Adults (18+) with a confirmed diagnosis of celiac disease who have enamel hypomineralization or demineralization, active carious lesions, and self-reported dentin hypersensitivity who can comply with a six-month home regimen are ideal candidates.

Not a fit: People without confirmed celiac disease, without enamel defects or dentin hypersensitivity, those currently using other remineralizing treatments, pregnant or breastfeeding individuals, or those unable to comply with follow-up are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the regimen could reduce tooth sensitivity and support enamel remineralization in adults with celiac-related enamel defects.

How similar studies have performed: Hydroxyapatite-based oral products have shown efficacy in reducing sensitivity and aiding remineralization in prior studies, but use specifically targeted to celiac-associated enamel defects is relatively novel.
