biomimetic hydroxyapatite, enamel remineralization
Brief summary
The aim of the following study is to evaluate che clinical efficacy of a toothpaste with biomimetic hydroxyapatite for the management of Molar-Incisor Hypomineralization. Patients who agree to participate to the study will use Biorepair toothpaste for the first 7 days of the month for 3, 6 and 9 months. The following indices will be measured: BEWE, Bleeding Index, Gingival index, Plaque index and the dental sensitivity test. The contralateral tooth will be used as control if not affected by MIH; otherwise, adjacent teeth will be considered.
Detailed description
Informed consent will be signed by the parents of the patients underage; patients will be asked the approval for the attendance of the study. Adult patients will sign the informed consent for the treatment and for processing personal data for research purpose, with their approval for the attendance of the study. Patients will be given for free a toothpaste with biomimetic hydroxyapatite (Biorepair Enamel-Repair Shock Treatment) and the Investigator will explain the correct procedures for home oral care. The toothpaste will be applied the first 7 days of the month for 9 months with a specific tray. Teeth will be randomly assigned to: * Trial group: 1 tooth with MIH from 1 quadrant will be treated with the biomimetic hydroxyapatite toothpaste. The applications will be performed for the first 7 days of the month for 9 months (1 application per day that lasts 10 minutes). * Control group: 1 contralateral tooth with MIH will not be treated with the biomimetic hydroxyapatite toothpaste Patients will be visited after 1, 2, 3, 6 and 9 months from the baseline. For each visit, BEWE index, Bleeding Index, Gingival index, Plaque index and Dental sensitivity test. Tooth with MIH will be assessed, together with its contralaterals as control. If the contralateral tooth should suffer from MIH too, measurements will be carried out on the adjacent tooth.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of BI - Bleeding Index | Study begin, 1,2,3, 6 and 9 months | Scoring criteria: * 0: absence of bleeding after 30 seconds * 1: bleeding observed after 30 seconds * 2: immediate bleeding |
| Change of GI - Gingival Index (Loe and Silness, 1963) | Study begin, 1,2,3, 6 and 9 months | Scoring criteria: * 0 = normal gingiva. * 1 = mild inflammation, edema and swelling; no bleeding. * 2 = moderate inflammation with edema, swelling and bleeding on probing. * 3 = severe inflammation with marked edema, redness tissues, ulceration and spontaneous bleeding. |
| Change of PCR - Plaque Control Record (O'Leary, 1972) | Study begin, 1,2,3, 6 and 9 months | 4 surfaces scored (mesial, distal, vestibular, labial/palatal) per tooth by means of plaque relevator. The Index is calculated multiplying the total number of surfaces with plaque per 100. |
| Change in Schiff Air Index - Dental sensitivity test | Study begin, 1,2,3, 6 and 9 months | Scoring criteria: 0\. the subject did not respond to air blasting; 1. the subject responded to air blasting; 2. the subject responded to air blasting and requested discontinuation; 3. the subject responded to air blasting, requested discontinuation and considered the stimulus to be painful. |
| Change of BEWE Index - Basic Erosive Wear Examination (Barlet et al., 2008) | Study begin, 1,2,3, 6 and 9 months | Scoring criteria: * 0: no erosive tooth wear; * 1: initial loss of surface texture; * 2: distinct defect, hard tissue loss \< 50% of the surface area; * 3: hard tissue loss ≥ 50% of the surface area. Additionally, risk level for clinical management will be assessed. |
