Cystic fibrosis


ICD-10: E84.8

ORPHA: 586

General information

Estimated occurrence
60:1,000,000 inhabitants.
Damage or mutation in a gene on chromosome 7, which leads to a reduced ability of the cells to bind water. The disease is inherited autosomal recessively.
General symptoms
There is a wide variation in severity and symptoms in people with cystic fibrosis (CF). CF progressively deteriorates over the years, but the consequences of the disease can be delayed. The mucus producing glands in the body do not function normally, resulting in viscous mucus that is difficult to remove. The lungs and gastrointestinal tract are especially affected. This causes coughing, breathing difficulties, proneness to infections in the lungs, as well as difficulties to digest food. The most common sign in young children is that they do not gain weight. The disease is usually discovered during the first year of life. Another sign of CF is exceptionally salty sweat.
CF, Pancreatic cystic fibrosis. Mucoviscidosis

Orofacial/odontological symptoms

Persons with the diagnosis may have difficulties in breathing through the nose and mouth breathing increases the risk of dry mouth. Some people may suffer from gastroesophageal reflux (acid reflux) which in time may increase the risk of enamel damage. Prolonged treatment with antibiotics likely explains why children with cystic fibrosis have fewer cavities than might be expected. Prolonged antibiotic treatment is commonly associated with fungal infection of the mouth.

Advice on follow-up and treatment

  • Many of these children and adults require extra prophylactic dental care.
  • In case of fungal infection in the mouth, there are effective prescription drugs available.
