Hydroxyapatite-Based Home Treatment for Dentin Sensitivity in Celiac Patients

Recruiting now · Not applicable

Conditions studied: Celiac Disease, Dentin Hypersensitivity, Tooth Demineralization

In brief

This single-center, randomized controlled clinical trial aims to evaluate the effectiveness of a home-based treatment using hydroxyapatite-based oral care products in adult patients with celiac disease who exhibit enamel demineralization and dentin hypersensitivity. Forty patients will be enrolled and randomly allocated into two parallel groups. The control group will perform home oral hygiene using only a hydroxyapatite-based toothpaste (Biorepair® Total Protection) twice daily. The trial group will follow the same regimen with the toothpaste, but will also apply a hydroxyapatite mousse (Biorepair® Plus Intensive Enamel Repair) once every evening before bedtime throughout the study period. The primary objective is to assess the reduction in dentin hypersensitivity using the Schiff Air Index. Secondary outcomes include changes in plaque accumulation (Plaque Index), gingival bleeding (Bleeding on Probing), pain perception (Visual Analogue Scale), and caries experience (DMFT and DMFS indices). Enamel demineralization will be analyzed through near-infrared transillumination (DIAGNOcam), laser fluorescence (DIAGNOdent), and digital image analysis (ImageJ software). All clinical parameters will be evaluated at baseline and after 1 week, 1 month, 3 months, and 6 months. The study seeks to determine whether the addition of a remineralizing mousse to daily oral care provides superior benefits in reducing sensitivity and improving enamel integrity in patients with celiac disease.
