Hydroxyapatite-Based Home Treatment for Dentin Sensitivity in Celiac Patients

Participants assigned to the experimental arm will use Biorepair® Total Protection toothpaste twice daily (morning and evening) and apply Biorepair® Plus Intensive Enamel Repair mousse once daily before bedtime, for a total of 6 months. The toothpaste contains microRepair® particles (zinc-substituted hydroxyapatite), designed to occlude dentinal tubules and promote enamel remineralization. The mousse, applied at night, enhances remineralization through higher concentrations of active hydroxyapatite. This combined regimen targets the reduction of dentin hypersensitivity and enamel demineralization in adult patients with celiac disease.

Participants assigned to the control arm will use Biorepair® Total Protection toothpaste twice daily (morning and evening) for 6 months. The toothpaste formulation contains microRepair® (zinc hydroxyapatite) to support daily enamel protection and tubule occlusion, without the adjunctive effect of the mousse. This arm is used to assess the baseline efficacy of the toothpaste alone compared to the combined regimen.
