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) is a group of inherited disorders characterized by abnormal enamel formation. This article outlines the treatment aspect for rehabilitation of occlusion using telescopic overdenture for a patient having amelogensis imperfecta.

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 ...

To study human evolution [4], researchers sometimes use microstructures found in human teeth and their knowledge of the processes by which those structures grow. Human fetuses begin to develop teeth in utero. As teeth grow, they form a hard outer substance, called enamel, through a process called amelogenesis. During amelogenesis, incremental layers of enamel form in a Circadian rhythm. This rh...

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...
