Enamel formation depends on a triad of tissue-specific matrix proteins (amelogenin, ameloblastin, and enamelin) to help initiate and stabilize progressively elongating, thin mineral ribbons of hydroxyapatite formed during an appositional growth phase. Subsequently, these proteins are eradicated to facilitate lateral expansion of the hydroxyapatite crystallites. The purpose of this study was to ...
Amelogenesis Imperfectas (AIs) are clinically and genetically heterogeneous conditions characterized by a wide range of clinical features. These abnormalities of enamel formation are categorized into three main groups, hypoplastic, hypomaturation and hypocalcified with different modes of inheritance such as autosomal recessive (AR), autosomal dominant (AD) and X-lined recessive (XLR). In spite ...
