1. NCDs in Korea

A non-communicable disease (NCD) is a disease that is not transmissible directly from one person to another. NCDs include Parkinson's disease, autoimmune diseases, strokes, most heart diseases, most cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Alzheimer's disease, cataracts, and others(table 1). NCDs may be chronic or acute. Most are non-infectious, although there are some non-communicable infectious diseases, such as parasitic diseases in which the parasite's life cycle does not include direct host-to-host transmission. NCDs are very important because they ultimately play an important function, action, and prevention in oral health directly or indirectly. So, I would like to introduce it because it is actively researched on the relationship with oral diseases worldwide.
NCDs change over the past 30 years in Korea(table 2). Again, cancer is the undisputed number one (27.5%), and the rate is overwhelmingly increasing. There are many different types, but we omit them. The second is vascular disease (24.7%). In detail, heart disease 10.5%, cerebrovascular disease 7.3%, diabetes 2.7%, Alzheimer's disease 2.3%, and hypertensive disease 1.9%.And the last one is lung disease (10%), pneumonia 7.9%, and chronic airway disease 2.1%. Lastly, intentional self-harm or suicide (4.7%).
