[Non-communicable disease and their significance for dental medicine].

Non-communicable diseases (NCDs), such as cardiovascular diseases, chronic respiratory diseases, cancers, and diabetes mellitus, are responsible for most deaths worldwide. In view of the rising prevalence and the long-term consequences of NCDs, their prevention is a public health priority. Dentistry plays an important role in this endeavor. Since oral and general diseases share common risk factors (e.g., poor oral hygiene, unhealthy diet, alcohol abuse, tobacco consumption, distress), preventive measures may target both oral diseases (e.g., dental caries, periodontal diseases, oral tumors) and medical NCDs. Consequently, dental medicine assumes an important medical and social role, which has been recognized by the World Health Organization and the General Assembly of the United Nations. To fulfill its mission successfully, consideration of the principles of evidence-based dentistry is a prerequisite. At the same time, the new development provides dentistry with the opportunity to critically reflect on its current and future orientation.
