Preventive maintenance therapy for the oral effects of TDO involve frequent dental cleanings, professional application of desensitizing medication, diet counseling, and oral hygiene instructions in proper home care and maintenance; medicated dental rinses and toothpastes are also prescribed as people suffering from TDO are more prone to oral hard tissue disease and early tooth loss. If restorative dentistry is performed without orthodontics to correct the protrusion of the lower jaw, a dental night guard worn at bedtimes on the upper or lower teeth to protect them from the effects of grinding may be recommended.

In extreme cases, tooth loss is inevitable, and the patient will consult with a prosthodontist to determine tooth replacement options such as dental implants, or partial dentures. There is no cure for TDO, but managing its oral and systemic affects is key to having the most favorable outcome from the disease. As the person affected by TDO ages, increased bone fractures may occur. The person suffering from TDO should watch for any pimple like masses on the gum tissue, pain or soreness in the teeth and gums, broken or chipped teeth, feeling of water in the ear or severe pain in the extremities which could indicate fracture.

The hair, teeth, and skeletal side effects of TDO are lifelong, and treatment is used to manage those effects. A person with TDO has the same life expectancy as a person without TDO. There are no cures or medications used to treat systemic effects of TDO, but medications for the frequent ear and dental infections can be used to manage its symptoms. A team based approach between dental specialists, oral and maxillofacial surgeons, and physicians is necessary for treating the systemic effects and improves the prognosis. It is also recommended for affected individuals to seek counseling to be better able to cope with any psychosocial problems due to oral and facial abnormalities that occur with TDO.

At home, a person suffering from TDO may be instructed to use frequent deep conditioning treatments and low manipulation hair styling to control shedding and hair loss. Clinical treatment involves the use of radiology to determine the effects that TDO has had on the surrounding teeth and bone structures. A series of appointments with the healthcare team are usually necessary to correct TDO abnormalities with treatment duration lasting from several months to through full oral-facial maturation stages.

Endodontic procedures are routinely recommended due to treatdental pulp exposure or periodontal abscess. Maxillofacial surgery may be required to establish a more appropriate mastication, skeletal, and esthetic relationship vertically between the teeth to improve functioning. Esthetic procedures such as dental crown (dentistry) or veneer (dentistry) are often performed to improve the physical look of the teeth and to strengthen the weak enamel caused by TDO.

Treatment of manifestations: special hair care products to help manage dry and sparse hair; wigs; artificial nails; emollients to relieve palmoplantar hyperkeratosis.

There does not yet exist a specific treatment for IP. Treatment can only address the individual symptoms.

Most patients with hyper IgE syndrome are treated with long-term antibiotic therapy to prevent staphylococcal infections. Good skin care is also important in patients with hyper IgE syndrome. High-dose intravenous gamma-globulin has also been suggested for the treatment of severe eczema in patients with HIES and atopic dermatitis.

Individuals affected by certain ED syndromes cannot perspire. Their sweat glands may function abnormally or may not have developed at all because of inactive proteins in the sweat glands. Without normal sweat production, the body cannot regulate temperature properly. Therefore, overheating is a common problem, especially during hot weather. Access to cool environments is important.

In the 1960s and 1970s, several studies were conducted sponsored by the U.S. Atomic Energy Commission, with the aim of finding a link between genetics and hypodontia.

The oral rehabilitation of hypodontia, especially where a significant number of teeth have not developed, is often a multidisciplinary process, involving a specialist orthodontist, a consultant in restorative dentistry, and a paediatric dentist in the earlier years. The process of treating and managing hypodontia begins in the early years of the patient's dentition where absent teeth are identified and the process of maintaining the remaining teeth begins. This is largely conducted by the paediatric dentist with orthodontic input. Once all the adult teeth have erupted the orthodontist is likely to liaise with the restorative dentist regarding optimal positioning of teeth for subsequent replacement with prosthodontic methods. This may include the utilisation of a resin-retained bridge and implants for spaces or composite resin, veneers or crowns where teeth are diminutive or misshaped.

Several studies have examined salivary flow rate in individuals and found parotid and submandibular salivary flow ranging from 5 to 15 times lower than average. This is consistent with the salivary glands being of ectodermal origin, although some findings have suggested that there is also mesodermal input.

Sabinas brittle hair syndrome is inherited as an autosomal recessive genetic trait.

In a study by Howell et al. patients were located and studied by means of complete histories and physical examinations, analyses of serum trace metals, ceruloplasmin concentration, urine and serum amino acids, and routine metabolic urine screens. In addition, serum and urine luteinizing hormone (LH) and follicle-stimulating hormone (FSH) values were determined, and were interpreted in conjunction with total plasma estrogen, estradiol, and testosterone levels. Close examination demonstrated the scalp hairs were very brittle, coarse, wiry in texture, and broke off quite easily with mechanical trauma such as combing and brushing. Some hairs could be visualized in their follicles, which were broken off at the skin line. Most patients had accompanying hyperkeratosis (thickening of the skin) of moderate degree on exposed surfaces. Maxillary hypoplasia (midfacial retrusion) was significant in many patients. The brittle, short hair, reduced eyelashes, crowded teeth, and dull appearance created a characteristic facial appearance. Post-pubertal patients had development of secondary sexual characteristics consistent with their age, except for sparse pubic escutcheons. All cases studied demonstrated some degree of mental deficiency; I.Q.'s ranged between 50–60. A deficiency in eye–hand coordination was also noted.

HIES was first described by Davis et al. in 1966 in two girls with red hair, chronic dermatitis, and recurrent staphylococcal abscesses and pneumonias. They named the disease after the biblical figure Job, whose body was covered with boils by Satan. In 1972, Buckley et al. described two boys with similar symptoms as well as coarse facies, eosinophilia, and elevated serum IgE levels. These two syndromes are thought to be the same and are under the broad category of HIES.

CCCA tends to present itself in the 20s and progresses over 20–30 years. One should consider this diagnosis in African Americans with what appears to be a female-pattern hair loss.

Currently there are no open research studies for otodental syndrome. Due to the rarity of this disease, current research is very limited.

The most recent research has involved case studies of the affected individuals and/or families, all of which show the specific phenotypic symptoms of otodental syndrome. Investigations on the effects of FGF3 and FADD have also been performed. These studies have shown successes in supporting previous studies that mutations to FGF3 and neighboring genes may cause the associated phenotypic abnormalities. According to recent studies involving zebrafish embryos, there is also support in that the FADD gene contributed to ocular coloboma symptoms as well.

Future research studies are required in order to better grasp the specific relationship between the gene involved and its effect on various tissues and organs such as teeth, eyes, and ear. Little is known and there is still much to be determined.

There is currently no specified treatment for individuals suffering from otodental syndrome. Considering that there are many possible genetic and phenotypic associations with the condition, treatment is provided based on each individual circumstance. It is recommended that those affected seek ear, nose & throat specialists, dental health specialists, and facial oral health specialists immediately; in order to determine potential treatment options.

Common treatment methods given are:

- Dental treatment/management – which can be complex, interdisciplinary and requires a regular follow up. Tooth extraction(s)and if needed, medications may be administered for pain, anxiety, and anti-inflammation. The affected individual is usually placed on a strict and preventative dental regiment in order to maintain appropriate oral hygiene and health.

- Endodontic treatment – individuals consult with an endodontist to analyze the individuals dental pulp. Typically endodontic treatment proves to be difficult due to duplicated pulp canals within the affected teeth. There may be a need for multiple extractions as well. Dental prosthesis and/or dental implants may be necessary for individuals that lack proper oral function, appearance, and comfort.

- Orthodontic treatment – given the predicament of the size and location of the affected oral area, molars and canines, orthodontic treatment is generally required in order treat any problems associated with the individuals bite pattern and tooth appearance.

- Hearing aids – in some cases affected individuals will suffer from hearing imparities and it may be necessary for hearing aid use.

The functional prognosis is mostly good with those that suffer from otodental syndrome. Appropriate dental treatment, hearing aids, and visitation to necessary specialists are recommended. Quality of life may be affected by psychological and functional aspects. It is also recommended that genetic counseling be given to families that have or may have this condition.

Treatments for CCCA remain investigational. Altering hair care practices has not been proven to assist in hair rejuvenation. High-dose topical steroids, antibiotics, immunomodulators such as tacrolimus (Protopic) and pimecrolimus (Elidel), and anti-androgen/5alpha Reductase inhibitors have been used with unknown efficacy.

Sabinas brittle hair syndrome, also called Sabinas syndrome or brittle hair-mental deficit syndrome, is an autosomal recessive congenital disorder affecting the integumentary system.

There is currently no cure for GAPO syndrome, but some options are available to reduce the symptoms. Nearsightedness, which affects some sufferers of the disease, can be treated by corrective lenses. Unfortunately, optic atrophy as a result of degradation of the optic nerve (common with GAPO syndrome) cannot be corrected. Corticosteroids have been proposed as a treatment for optic nerve atrophy, but their effectiveness is disputed, and no steroid based treatments are currently available.

Marie Unna hereditary hypotrichosis (also known as "Marie Unna hypotrichosis") is an autosomal dominant condition characterized by scalp hair that is sparse or absent at birth, with variable coarse, wiry hair regrowth in childhood, and potential loss again at puberty.

The original report was of a family in Cardiff, United Kingdom. There are subsequent reports of patients from the USA, France, Australia, UAE, India and from Cuba.

Clouston's hidrotic ectodermal dysplasia (also known as "Alopecia congenita with keratosis palmoplantaris," "Clouston syndrome," "Fischer–Jacobsen–Clouston syndrome," "Hidrotic ectodermal dysplasia," "Keratosis palmaris with drumstick fingers," and "Palmoplantar keratoderma and clubbing") is caused by mutations in a connexin gene, GJB6 or connexin-30, characterized by scalp hair that is wiry, brittle, and pale, often associated with patchy alopecia.

Hypohidrotic ectodermal dysplasia (also known as "anhidrotic ectodermal dysplasia", and "Christ-Siemens-Touraine syndrome") is one of about 150 types of ectodermal dysplasia in humans. Before birth, these disorders result in the abnormal development of structures including the skin, hair, nails, teeth, and sweat glands.

Hypotrichosis ("" + "" + "") is a condition of abnormal hair patterns, predominantly loss or reduction. It occurs, most frequently, by the growth of vellus hair in areas of the body that normally produce terminal hair. Typically, the individual's hair growth is normal after birth, but shortly thereafter the hair is shed and replaced with sparse, abnormal hair growth. The new hair is typically fine, short and brittle, and may lack pigmentation. Baldness may be present by the time the subject is 25 years old.

Hypotrichosis is a common feature of Hallermann–Streiff syndrome as well as others. It can also be used to describe the lack of hair growth due to chemotherapy.

The opposite of hypotrichosis is hypertrichosis, where terminal hair (thick) grows in areas that would otherwise normally have vellus hair (thin), for example abnormally thick facial hair growth in women.

Hay–Wells syndrome is also known as AEC syndrome; this is short for "ankyloblepharon–ectodermal dysplasia–clefting syndrome", "ankyloblepharon filiforme adnatum–ectodermal dysplasia–cleft palate syndrome", "ankyloblepharon–ectodermal defects–cleft lip/palate (AEC) syndrome", "ankyloblepharon–ectodermal defect–cleft lip and/or palate syndrome", or "ankyloblepharon ectodermal dysplasia and clefting". Hay–Wells syndrome, or Ankyloblepharon-Ectodermal Dysplasia-Clefting (AEC) syndrome, is one of over one-hundred forms of ectodermal dysplasia; a collection of inherited diseases that cause atypical development of nails, glands, teeth, and hair. Males and females are equally affected by Hay–Wells syndrome. No demographic has been shown to be especially susceptible to the syndrome. In the United States, Hay-Wells like syndromes occur in only one in 100,000 births. Symptoms are apparent at birth, or become apparent when atypical development of teeth occurs. Major symptoms of Hay–Wells syndrome include: sparse hair and eyelashes, missing teeth, cleft palate, cleft lip with fusing of the upper and lower eyelids, and deformed nails. Therefore, a diagnosis of Hay–Wells syndrome is largely based upon the physical clinical presentation of the patient.

Currently there is no specific treatment for this condition. Management is supportive.

Genetic forms of localized autosomal recessive hypotrichosis include:
