Ellis–van creveld syndrome is a rare autosomal recessive syndrome of the heart, skeleton and most of the ectodermal derivatives. It is caused due to genetic defects in the chromosome 4p16; it belongs to short rib-polydactyly group (SRP). It is characterized by short ribs, short limb, polydactyly, ectodermal dysplasia and congenital heart defects. The oral manifestation is one of the main charac...

© 2017 Indian Dermatology Online Journal | Published by Wolters Kluwer Medknow Ectodermal dysplasias are a heterogeneous group of disorders resulting from abnormalities of structures derived from embryonic ectoderm (skin, teeth, and appendage). Rapp Hodgkin Syndrome (RHS) is a type of anhidrotic ectodermal dysplasia, which was described by Rapp and Hodgkin in 1968.[1] This syndrome is character...

CASE REPORT This report describes the oral rehabilitation of a young boy with severe oligodontia of primary dentition and complete anodontia of permanent dentition, treated by complete maxillary and partial mandibular removable dentures. Since the determination of a proper occlusal vertical dimension in paediatric patients is often difficult, treatment was achieved by means of a multidisciplina...

X-linked recessive anhidrotic ectodermal dysplasia with immunodeficiency is a developmental and immunologic disorder caused by mutations in nuclear factor-kappaB essential modulator (NEMO), which is essential for nuclear factor-kappaB activation. Early in life, affected boys present a typical appearance, with hypotrichosis or atrichosis, hypohidrosis or anhidrosis, and hypodontia or anodontia w...

Hypotrichosis, an almost complete lack of teeth and the complete absence of eccrine nasolabial glands, was observed among the progeny of a normal cow of the black and white German Holstein breed. Similar congenital anomalies are known in humans and mice as X-linked anhidrotic ectodermal dysplasia (ED1), leading to the impaired formation of hair, teeth and sweat glands. The pedigree of the four ...

Aim: Dental number anomalies are a group of congenital developmental disorders divided into two groups supernumerary and missing teeth. This study was conducted to investigate the prevalence numeric dental using panoramic images in patients referred Hamadan Faculty. Methods: In this cross-sectional study, 2,197 radiographs aged 6-49 years were evaluated. These groups: 1) Supernumerary teeth, in...

The paper considers two observer-based rotor position estimation schemes for sensorless control of Interior Permanent Magnet Synchronous Machines (IPMSMs). Emphasis is given to techniques based on feedbacklinearisation followed by Luenberger observer design, and direct design of non-linear observers. Genetic Algorithms (GAS) based on the principles of evolution, natural selection and genetic mu...
