Amelogenesis Imperfecta

Common Name(s)

Amelogenesis Imperfecta

Amelogenesis imperfecta (AI) (amelogenesis - enamel formation; imperfecta - imperfect) is a disorder that affects the structure and appearance of the enamel of the teeth. This condition causes teeth to be unusually small, discolored, pitted or grooved, and prone to rapid wear and breakage. These dental problems, which vary among affected individuals, can affect both primary (baby) teeth and permanent teeth. There are 4 main types of AI that are classified based on the type of enamel defect. These 4 types are divided further into 14 subtypes, which are distinguished by their specific dental abnormalities and by their pattern of inheritance. AI can be inherited in an autosomal dominant, autosomal recessive or X-linked recessive pattern.

Oral health-related quality of life before and after crown therapy in young patients with amelogenesis imperfecta.
 

Author(s): Gunilla Pousette Lundgren, Agneta Karsten, Göran Dahllöf

Journal:

 

Amelogenesis imperfecta (AI) is a rare, genetically determined defect in enamel mineralization associated with poor esthetics and dental sensitivity. Because the condition is associated with negative social outcomes, this study evaluated oral health-related quality of life (OHRQoL), ...

Author(s): Samir Laouina, Siham Chafai El Alaoui, Rachida Amezian, Abderrahmane Al Bouzidi, Abdelaziz Sefiani, Mustapha El Alloussi

Journal:

 

Amelogenesis imperfecta is an inherited disease characterized by generalized structural abnormalities of the enamel on all teeth, including both primary and permanent dentition. To the best of our knowledge, this is the first case report of a rare association of amelogenesis imperfecta, ...

Evolutionary analysis of selective constraints identifies ameloblastin (AMBN) as a potential candidate for amelogenesis imperfecta.
 

Author(s): Frédéric Delsuc, Barbara Gasse, Jean-Yves Sire

Journal:

 

Ameloblastin (AMBN) is a phosphorylated, proline/glutamine-rich protein secreted during enamel formation. Previous studies have revealed that this enamel matrix protein was present early in vertebrate evolution and certainly plays important roles during enamel formation although its ...

The amelogenesis imperfectas (AIs) are a clinically and genetically diverse group of conditions that are caused by mutations in a variety of genes that are critical for normal enamel formation. To date, mutations have been identified in four genes (AMELX, ENAM, KLK4, MMP20) known ...

Dental enamel forms as a progressively thickening extracellular layer by the action of proteins secreted by ameloblasts. The most abundant enamel protein is amelogenin, which is expressed primarily from a gene on the X-chromosome (AMELX). The two most abundant non-amelogenin enamel ...
