imperfecta: a classification and catalogue for the 21st century.
12) The entire process of enamel formation is called amelogenesis
, while the mineralization process as such, which takes place between ions and proteins secreted by cells, is called biomineralization.
The treatment planning for patients with amelogenesis
imperfecta is related to many factors: the age, socioeconomic status of the patient, the type and severity of the disorder, and the intraoral situation.
Osseous lesions in the maxilla can represent ossifying fibroma, fibrous dysplasia, amelogenesis
imperfecta, or osteogenesis imperfecta.
Odontomas express cytokeratin 14, which is absent in advanced amelogenesis
, and cytokeratin 7, which is present in Hertwig root sheath and stellate reticulum.
Craniofacial structure related to inheritance pattern in amelogenesis
21) Calcium also participates in the stage of amelogenesis
in which there is loss of proteins from the matrix and input of calcium and potassium from the blood vessels that contribute to forming tooth enamel.
El fluoruro incorporado en el esmalte dental durante el periodo preeruptivo refleja su exposicion sistemica durante la amelogenesis
(5), por lo que el esmalte ha sido propuesto como marcador biologico de exposicion a fluoruro (6).
In addition, higher frequency of calculus accumulation was found also in children with amelogenesis
imperfecta [Stewart et al.
The term, "regional odontodysplasia," is the most widely employed, yet other terms, such as odontogenesis imperfecta, odontogenic dysplasia, nonhereditary amelogenesis
imperfecta, and ghost teeth are also found in the literature (REDMAN et al.
involves the formation of enamel by sheets of cells called ameloblasts.
Differential diagnosis may include hypocalcified form of amelogenesis
imperfecta, congenital erythropoietic porphyria, Kostmann's condition (conditions leading to early tooth loss), cyclic neutropenia, Chediak-Hegashi syndrome, histiocytosis X, Papillon-Lefevre syndrome, tetracycline discoloration and staining of the teeth, vitamin D-dependent and vitamin D-rickets.
Some of the affected persons had amelogenesis
El marcador mas clasico es la presencia de hipoplasia del esmalte que refleja fallos en la amelogenesis
que se manifiestan como bandas transversales rehundidas en la superficie de las piezas dentales.
, ingested low levels of fluoride (from food, water, or supplements) can replace the hydroxyl group in some of the hydroxyapatite crystals.
