Oral stereognostic ability: a test of oral perception.

Oral stereognosis (form or shape recognition in the oral cavity) can be utilized to assess oral perceptual abilities. This assessment can be beneficial in planning as well as predicting the future outcome of any treatment modality in the orodental region. This article provides a meta analysis of different studies conducted in the last fifty years to quantify magnitude of oral sensory capacity using oral stereognostic ability tests and their implication in clinical dental sciences.

Hypohidrotic ectodermal dysplasia (HED).

Hypohidrotic Ectodermal Dysplasia (HED) is a hereditary congenital disorder of ectodermal origin. It is characterized by lack of sweat glands (hypohidrosis), nail dystrophy(onychodysplasia), alopecia (hypotrichosis), defective palms and soles (palmoplantar hyperkeratosis) and the oral presentations of partial absence of teeth (hypodontia) or complete absence of teeth (anodontia). Hypodontia of primary and permanent dentition is one of the most frequently occurring oral symptoms in HED patients.
