Remineralization Potential of MI Varnish Versus Fluoride Varnish on White Spot Lesions in Maxillary Primary Incisors

Early childhood caries (ECC) is a very common and consequential chronic disease affecting young children ( Çolak et al., 2013). The prevalence of ECC in Egypt is high, it is about (78%) according to the last Egyptian Report, 2014. ECC begins with white-spot lesions, and caries can progress continuously, leading to complete destruction of the crown. Calcium and phosphate ions are more readily lost for children because lower mineralization of deciduous enamel. The disease usually develops very quickly and causes many childhood health problems, such as caries-related toothache and infection. Demineralization and remineralization are dynamic processes in caries initiation, progression, and reversal. Therefore, regulation of the demineralization- remineralization balance is a key to caries prevention and treatment. The ideal method of increasing remineralization is reconstructing the depleted tissues with hydroxyapatite, which is the same inorganic component as the enamel. Fluoride varnishes have been the standard practice for the professional application of fluoride. Casien PhosphoPeptide (CPP) is a sticky protein that binds and stabilizes calcium and phosphate ions in an amorphous state. CPP-ACP has been shown to adhere to teeth surfaces.
