BACKGROUND It is not known why the ameloblasts responsible for dental enamel formation are uniquely sensitive to fluoride (F(-)). Herein, we present a novel theory with supporting data to show that the low pH environment of maturating stage ameloblasts enhances their sensitivity to a given dose of F(-). Enamel formation is initiated in a neutral pH environment (secretory stage); however, the pH...
Amelogenesis Imperfecta (AI) is a clinical diagnosis that encompasses a group of genetic mutations, each affecting processes involved in tooth enamel formation and thus, result in various enamel defects. The hypomaturation enamel phenotype has been described for mutations involved in the later stage of enamel formation, including Klk4, Mmp20, C4orf26, and Wdr72. Using a candidate gene approach ...
زمینه: آملوژنزیس ایمپرفکتا (ai) مجموعه ای از نقایص وراثتی مینای دندان است که هر دو سری دندانهای شیری و دائمی را تحت تاثیر قرار می دهد و اختلالات کمیتی و کیفیتی مینای دندان را در پی دارد. این ناهنجاری، ناهمگونی ژنتیکی و فنوتیپی را نشان می دهد و ممکن است با تغییرات ژنتیکی و مورفولوژیکی دیگری در بدن همراه باشد. هدف: تعیین جهش های ژنهای ,klk4 ,mmp20 ,enam fam83h در فرمهای غیر سندرمی اتوزومی آملوژ...
To the Editor : Amelogenesis imperfecta (AI) is a collection of nonsyndromic inherited diseases featuring a variety of abnormal enamel phenotypes, patterns of inheritance, and causative genes. The term is also used to indicate the presence of an enamel phenotype in syndromes. Dental enamel is the most highly mineralized tissue in the body, lacks collagen, and is the product of specialized epith...
Amelogenesis imperfecta (AI) is a rare, genetically determined defect in enamel mineralization. Patients with (AI) can present with rapid tooth loss or fractures of enamel and dental sensitivity as well as alterations in enamel thickness, color, and shape. These factors may compromise esthetic appearance and masticatory function. Existing treatment recommendations suggest using resin composite ...
