Hypohidrotic ectodermal dysplasia: A rare entity.

Hypohidrotic ectodermal dysplasia (HED) is a genetic disorder which involves a complex group of inherited conditions. This condition is characterised by the failed development of two or more ectodermal derived anatomic structure; for example, the skin, hair, nails, teeth, and sweat glands. It is a phenotypically heterogenous group of illnesses including anodontia with conical teeth, generalised spacing, reduced ability to sweat, very less hair growth, etc. The pattern of inheritance of HED varies from person to person depending on the type of ectodermal dysplasia (ED). The patterns include X-linked recessive, X-linked dominant, autosomal dominant, autosomal recessive, and spontaneous mutation. There is one such common type of ED more in female than male. It is an X-linked HED (XLHED), characterised by hypohidrosis, sparse hair, and teeth abnormalities. The other type can affect both male and female equally and may be inherited in different ways. The present case is a 21-year-old male who presented with hair, teeth, and sweat gland abnormalities.

Rickets - A case report.

Rickets is a disorder caused by a lack of vitamin D, calcium or phosphate. It leads to softening and weakening of the bones. Dental manifestation of rickets includes enamel hypoplasia and delayed tooth eruption. The most important oral findings are characterised by spontaneous gingival and dental abscesses occurring without a history of trauma or caries. Radiographic examination revealed large pulp chambers, short roots, poorly defined lamina dura and hypoplastic alveolar ridge. These dental abscesses are common, and therefore, extraction and pulpectomy are the treatment of choice. Oral manifestations of rickets should be diagnosed early by both physicians and dentists to prevent severe dental complications. This article aims to report a case of rickets in a 3-year-old girl, describing the dental findings and the treatment to be performed in these cases.
