Anodontia is a rare genetic disorder characterized by the congenital absence of all primary or permanent teeth.

The defect results in the dental lamina obstruction during embryogenesis due to local, systemic and genetic factors.

Anodontia being the term used in controlled vocabulary Medical Subject Headings (MeSH) from MEDLINE which was developed by the United States National Library of Medicine.

The congenital absence of at least one permanent tooth is the most common dental anomaly and may contribute to masticator dysfunction, speech impairment, aesthetic problems, and malocclusion (Shapiro and Farrington 1983).

[4] Symptoms that are associated with anodontia include: alopecia, lack of sweat glands, cleft lip or palate, and missing fingernails.

In the rare case that ectodermal dysplasia is not present, anodontia will be caused from an unknown genetic mutation.

In the rare case that ectodermal dysplasia is not associated or present, anodontia will be caused by an unknown genetic mutation.

Other symptoms associated with anodontia include: Alopecia, loss of sweat glands, cleft lip or palate, or missing finger nails.

[4] The complications associated with anodontia can vary but the majority results in problems with aesthetic appearance, speaking, and masticatory function.

The use of an implant prosthesis in the lower jaw could be recommended for younger patients as it is shown to significantly improve the craniofacial growth, social development and self-image.

The study associated with this evidence worked with individuals who had ectodermal dysplasia of varying age groups of up to 11, 11 to 18 and more than 18 years.

[5] Overall the use of an implant-prosthesis has a considerable functional, aesthetic and psychological advantage when compared to a conventional denture, in the patients.

Once anodontia is diagnosed, dental implants or dentures will need to be worn in order to treat this disorder.

[8] A recent study in 2019 by R. Constance Wiener and Christopher water looked at anodontia, hypodontia, and oligodontia in children West Virginia.

There is a high prevalence of children with missing permanent teeth in West Virginia compared to the rest of the nation.

[10] The family reported no problems with retention and began a monthly recall visit in order to monitor any eruptions of teeth or adjustments that needed to be made.

[11] The patient also had sensitivity to heat, absence of sweating, dry skin, absent eyebrows and eyelashes, hyper pigmentation, and many other ectodermal dysplasia symptoms.
