Aim: This clinical report of two cases describes the prosthodontic management of Hypohidrotic ectodermal dysplasia patient. Background: Hereditary ectodermal dysplasia is a specific syndrome characterized by congenital absence or deficient functions of two or more ectodermal structures and their accessory appendages manifested primarily by three clinical signs as hypotrichosis, hypodontia / anodontia (true) & hypohydrosis / anohydrosis. The most frequently reported ectodermal dysplasia syndrome is X-linked hypohidrotic ectodermal dysplasia. It may not be apparent in the first year of life but it is usually diagnosed during infancy, after a bout of fever of unknown origin. Ectodermal dysplasia is commonly a difficult condition to manage with prosthodontics because of the typical oral deficiencies and the afflicted individuals are quite young when they are evaluated for treatment. It is important that these individuals receive dental treatment at an early age for physiologic & psychological reasons. Case description: The treatment was focused on esthetic needs and oral functions & included fabrication of removable prosthesis for both the patient as inexpensive, reversible & conservative treatment approach. Conclusion: This clinical report demonstrates the importance of prosthodontic treatment for oral rehabilitation for ectodermal dysplasia patients. Clinical significance: The prosthodontic management of hypohidrotic ectodermal dysplasia patients with the condition of partial & complete absence of teeth by overdenture & complete denture prosthesis respectively, improved their physiological & psychological condition.
