Trichodysplasia and amelogenesis imperfecta

Oral Surgery, Oral Medicine, Oral Pathology, 1993
This paper describes a family in which members of two generations have an X-linked type of enamel dysplasia. All affected persons have symmetric pits in the cuticles of their hair shafts. The observation of these concurrent traits raises questions about the classification of amelogenesis imperfecta and the value of microscopic studies of the hair in ...

Role of Lysosomes in Amelogenesis

Nature, 1969
PREVIOUS 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 with taurodontism

Oral Surgery, Oral Medicine, Oral Pathology, 1979
Reports of families having a combination of amelogenesis imperfecta and taurodontism are limited. This study of members of three families shows that the combination is inherited as an autosomal dominant trait. In each of the patients examined, neither condition was seen without the other.

Amelogenesis imperfecta in cattle

Veterinary Record, 2011
PATHOLOGICAL 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 ...

Multidisciplinary treatment of amelogenesis imperfecta

Nederlands Tijdschrift voor Tandheelkunde, 2021
A healthy 13-year-old patient with amelogenesis imperfecta was referred by her orthodontist to the joint consultation hour (Center for Specialised Dentistry and Oral and Maxillofacial Surgery). In addition to her amelogenesis imperfecta, she was diagnosed with a class 2 malocclusion and a mandibular hypoplasia.

Amelogenesis In Vitro

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.

Histochemical study of amelogenesis and dentinogenesis

Oral Surgery, Oral Medicine, Oral Pathology, 1957
Summary 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: Case Study

Operative Dentistry, 2017
SUMMARY 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.
