Amelogenesis imperfecta (AI) is a hereditary disorder expressing a group of conditions that cause developmental alterations in the structure of enamel. AI is a serious problem that reduces oral health-related quality of life and causes some physiological problems. The treatment of patients with AI may upgrade the quality of life and reinforce their self-esteem. The Al trait can be transmitted b...

BACKGROUND/AIMS Calcium homeostasis requires regulated cellular and interstitial systems interacting to modulate the activity and movement of this ion. Disruption of these systems in the kidney results in nephrocalcinosis and nephrolithiasis, important medical problems whose pathogenesis is incompletely understood. METHODS We investigated 25 patients from 16 families with unexplained nephroca...

Amelogenesis imperfecta (AI) is an inherited disorder which results in enamel defects. The main clinical characteristics are extensive loss of tooth tissue, poor esthetics and tooth sensitivity. Early recognition followed by appropriate preventive care and oral rehabilitation is essential in the successful management of AI. This clinical report describes the management of a 3 year-old girl with...

Amelogenesis Imperfecta (AI) represents a group of developmental conditions, genomic in origin, which affect the structure and clinical appearance of enamel of all or nearly all the teeth in a more or less equal manner. It is usually inherited either as an X-linked, autosomal dominant or autosomal recessive trait. The enamel may be hypoplastic, hypomineralised or both and affected teeth may be ...

NTRODUCTION Amelogenesis Imperfecta (AI) is a developmental disorder of genomic origin, associated with abnormal enamel formation. Although AI is considered as a single disease entity, it actually represents a group of heterogeneous conditions, with diverse structural defects of enamel resulting in a range of clinical phenotypes. 1 It is characterized by clinical and genetic heterogeneity in th...

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 ...

background: amelogenesis imperfecta (ai) is an inherited tooth disorder. despite the fact that up to now, several gene muta­tions in mmp20, enam, amelx and klk4 genes have been reported to be associated with ai, many other genes sug­gested to be involved. the main objective of this study was to find the mutations in three major candidate genes including mmp20, enam and klk4 responsible for ai f...
