The study will also observe the possible etiological factors that might predispose hypomineralization of primary teeth.\n\nTo 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.",[50,51,52,25],"Molar Incisor Hypomineralisation","Molar Incisor Hypomineralization","Hypomineralization Molar Incisor","2024-12-11",{"date":29,"type":30},{"date":32,"type":21},{"date":57,"type":21},"2026-02",{"name":36,"class":37}]
