Molar Incisor Hypomineralization (MIH) is a common developmental enamel defect affecting children, particularly in Dubai, where it contributes to hypersensitivity, esthetic concerns, plaque accumulation, and increased caries risk. These complications often lead to premature tooth extraction and orthodontic issues, negatively impacting children's oral health-related quality of life. This randomized, open-label clinical trial aims to compare the remineralization efficacy of a fluoride-free hydroxyapatite toothpaste with a conventional fluoride toothpaste in children aged 6-12 years diagnosed with mild to moderate MIH. Participants will be recruited from Dubai Health pediatric dental clinics, with inclusion criteria requiring at least one affected permanent molar or incisor, good general health, parental informed consent, and the child's assent. Children with systemic conditions affecting enamel or recent use of desensitizing treatments will be excluded. Primary outcome assessment will involve Quantitative Light-Induced Fluorescence-QLF at baseline, 3, 6, 9, and 12 months. The images were analyzed using a commercial software program (Inspektor QLF 1.97, Inspektor Research Systems, Amsterdam, The Netherlands) to determine the change in fluorescence (ΔF, %) and extension of the lesion (area; mm2). Secondary outcome measures will include enamel fluorescence readings using the DIAGNOdent Pen. After prophylaxis and air-drying, three readings per lesion will be recorded, with mean and peak values analyzed to monitor mineralization. Hypersensitivity in MIH-affected teeth will be assessed using air stimulus (Schiff scale) and Visual Analogue Scale (VAS) at baseline, 3, 6, 9, and 12 months. Oral health-related quality of life (OHRQoL) will be measured using age-appropriate validated questionnaires to evaluate the impact of MIH and treatment over time. This study also responds to growing parental concerns about fluoride exposure and the demand for safer, fluoride-free alternatives. By evaluating the clinical effectiveness of hydroxyapatite toothpaste, the trial aims to inform evidence-based preventive strategies for MIH management. The findings may guide clinical practice and public health recommendations, ultimately improving oral health outcomes for affected children.
NCT07162077
Objectives: to compare aesthetic effectiveness of resin infiltration with/without using sodium hypochlorite in managing opacities of MIH on incisors, and to compare parent's satisfaction with results of both application protocols. Methods: Twenty-four teeth with yellow/ brown opacities of MIH, will be diagnosed according to EAPD diagnostic criteria, will be randomly allocated to test or control group. In the test group, the investigators will be applied sodium hypochlorite 5.25% by using cotton wad before treatment, then after the first and second etching cycles (application of the Icon-Etch (ICON® -Etch; DMG, Hamburg, Germany) and Icon-dry (ICON® -Dry; DMG, Hamburg, Germany) according to the manufacturer's recommendations) as irrigation step and following the third -Etch etching cycle Icon-infiltrant (ICON® -Infiltrant; DMG, Hamburg, Germany) will be applied . In control group, the investigators will be applied the same protocol of test group but without using sodium hypochlorite. The masking efficacy will be analyzed using the Lab System to calculate the color difference (ΔE) between the opacity and the adjacent enamel in Adobe Photoshop 2024. The infiltration proportion of opacity will be measured using Image J software and the infiltrated area will be expressed as a percentage. The satisfaction of the parents with the results of both application protocols will be compared using Likert scale.
NCT06727539
The aim for thid study is to detect the prevalence of HSPM and the possible association between MIH and HSPM in a group of Egyptian children aged from 6-12 years. The study will also observe the possible etiological factors that might predispose hypomineralization of primary teeth. To our knowledge, there are no relevant studies that considered the prevalence of HSPM and its possible etiology in Egypt or its association with MIH. So, this study will address this knowledge gap. The possible relationship between HSPM and MIH is highly significant in pediatric dentistry, since the early diagnosis of HSPM as soon as second primary molars erupt makes it possible to initiate more intensive supervision and preventive measures, as these patients are otherwise prone to developing MIH in permanent teeth within a few years.
