Cystic fibrosis is a genetic disorder in which the mutation of the Cystis Fibrosis Transmembrane Conductance Regulator (CFTR) gene that codes the protein forming a chloride channel of epithelial cells results in its distorted functioning. The manifestations of the disorder are mainly observed in the respiratory and digestive system. Accumulation of sticky and thick mucus is the dominant clinical symptom; it leads to chronic infections and gradual tissue destruction. Although cystic fibrosis remains incurable, it is currently feasible to extend patients' life expectancy thanks to modern therapy possibilities. As cystic fibrosis is no longer the domain of pediatricians, health care to CF patients needs to be provided by doctors of various specializations. The multidisciplinary team of doctors should include a dentist aware of specific prevention and treatment needs of this group of patients. It results from the fact that in the course of cystic fibrosis it is possible to observe a variety of changes in the oral cavity environment. The study presents dental issues observed in CF patients and reported in literature. Particular attention was paid to dental caries, mineralization disorders of hard dental tissues, gingivitis and the change in the content and properties of saliva; moreover, prevention and treatment options regarding oral cavity health is this group of patients were taken into consideration.
