Role of Lysosomes in Amelogenesis
Nature, 1969PREVIOUS studies in amelogenesis have shown that the organic matrix of enamel undergoes marked changes during development. These include a loss of protein and a change in the amino-acid composition1–3. Experiments with labelled protein precursors show that label first appears in a discrete layer in the enamel but soon spreads throughout the matrix4,5 ...

Amelogenesis imperfecta in cattle
Veterinary Record, 2011PATHOLOGICAL conditions of the teeth are infrequently reported, particularly in cattle ([Brown and others 2007][1], [Radostits and others 2007][2]). These include malocclusion, porphyrinuria, and complex skeletal diseases such as osteogenesis imperfecta, dental fluorosis and enamel erosion ...

Protein dynamics of amelogenesis
The Anatomical Record, 1996The synthesis, secretion, and fate of matrix proteins released by ameloblasts during enamel formation was studied in continuously erupting rat incisors.Computerized image processing was used to quantify silver grain distribution in radioautographs of sections prepared from rats injected with 3H-methionine, and this was correlated with fluorographs ...

Journal of Dental Research, 1979
The processes by which diversity is acquired and maintained during embryogenesis have been repeatedly described but are as yet not understood. One fascinating example of diversity following gastrulation is epidermal organogenesis and in particular embryonic tooth morphogenesis.

The treatment of amelogenesis imperfecta
The Journal of Prosthetic Dentistry, 1976Abstract In treating amelogenesis imperfecta, the patient's appearance and restoration of occlusion are of prime importance. Modern methods and materials have widened the range of available treatment.

Calcification and amelogenesis in craniopharyngiomas
Oral Surgery, Oral Medicine, Oral Pathology, 1971Abstract A study of calcification and amelogenesis in eighty-four pituitary adamantinomas has confirmed the findings of others that diffuse calcification of islands of the cornified epithelium is the most common feature. It has been found that atypical amelogenesis in the form of enameloids and enamel droplets is also a common alteration which ...

Amelogenesis Imperfecta: Case Study
Operative Dentistry, 2017SUMMARY Amelogenesis imperfecta (AI) refers to a group of rare genetic disorders that involve tooth development and that are passed down through families as a dominant trait. This condition is characterized by abnormal enamel formation caused by gene mutations that alter the quality and/or quantity of enamel.

Histochemical study of amelogenesis and dentinogenesis
Oral Surgery, Oral Medicine, Oral Pathology, 1957Summary Based on the studies of Wislocki and co-workers, 31, 32 and of Todescan and Sasso, 30 we present a histochemical study on the existence of alkaline phosphatase, acid mucopolysaccharides, keratin, and calcium, and correlate the substances under study with the mechanism of the elaboration of the organic matrix and its consequent ...

Amelogenesis imperfecta:A Genetic Study
Human Heredity, 1988The mode of inheritance and the clinical manifestations of amelogenesis imperfecta (AI) were studied in 51 families from the county of Västerbotten, northern Sweden. Autosomal dominant (AD) was the most probable mode of inheritance in 33 families, but X-linked dominant (XD) inheritance was a possible alternative in one family.

Enamel Formation and Amelogenesis Imperfecta
Cells Tissues Organs, 2007Dental enamel is the epithelial-derived hard tissue covering the crowns of teeth. It is the most highly mineralized and hardest tissue in the body. Dental enamel is acellular and has no physiological means of repair outside of the protective and remineralization potential provided by saliva.
