Ectodermal dysplasia teeth treatment Virginia Dr. Ursula Klostermyer
Ectodermal dysplasia (ED): As the name describes: It is a disorder where a person has abnormal changes in the ectodermal structures and is a congenital disease. This does not show up as a single disorder but as a group of syndromes from changes of the ectodermal structures. More than 150 different syndromes have been identified. It can occur in any race, but it is most prevalent with Caucasians, especially fair Caucasians and is hereditary.
ED can be classified by inheritance (autosomal dominant, autosomal recessive, and X-linked) or by which structures are involved (hair, teeth, nails, and/or sweat glands).
It shows up as a change of two or more abnormalities of the ectodermal structures in a person:
Change of hair on scalp and body: hair appears thin, sparse, very light in color. The hair follicles are abnormally changed. The hair might grow sporadically and very slowly. Sometimes it is extremely fragile, curly or twisted.
Light skin pigmentation is prevalent with most ED patients. But in some cases, red or brown pigmentation might be present too.
A hypo-pigmentation is often occurring after a sustaining skin injury.
Often the skin of ED patients is prone to rashes or infections and can be thick over the palms and soles. Care must be taken to prevent cracking, bleeding, and infection.
Sweat glands in ED patients might function abnormally or -due to inactive proteins in the sweat glands- might not have developed at all. Without normal functioning sweat glands, a person cannot regulate temperature properly. Overheating might be a serious problem. Cooler environments and layering of clothes would be preferred for most ED patients.
Fingernails and toenails often are abnormally formed and mostly may be thick, abnormally shaped, discolored, ridged, brittle, or slow growing. The cuticles might be prone to infections.
ED patients are known for congenitally missing teeth. The lack of teeth for primary and secondary teeth is prevalent. Frequently seen are peg-shaped or pointed teeth in awkward tooth positions. A tooth absence, malformation, and mal-positioning is often the case.
The enamel (outer layer of the tooth) of teeth can be affected as well – it can be brittle and thin or malformed.
Patients with ED will need often from young, age on (often age 2 and above) the care of a specialized dentist – a prosthodontist, who can provide the patient with cosmetic and functional needs. During childhood, an ED, the patient might receive several sets of complete or partial dentures while the upper and lower arches grow during development. After the patient is grown dental implants might be an option. For mal-shaped enamel/teeth, crowning might be an option. Every patient is different and often a multi-disciplinary team of dental specialists (orthodontists, oral surgeons, prosthodontists) will help to optimize the often complex dental restorations.
Changes in craniofacial structures:
People with ED often have certain cranial-facial features which can be distinctive: a common change is the frontal bossing. Often longer or more pronounced chins are noticed. Frequently broader noses are also seen.
Some types of ED result in abnormal development of parts of the eye which can develop in dryness, of the eye, cataracts, and vision defects. Professional eye care can help minimize the effects of ED on vision. In addition abnormalities in the development of the ear may cause hearing problems.
With the reduction of normal protective secretions, respiratory infections can be more common. Precautions must be taken to limit those infections.
