Oral health is a branch of health science that focuses on the prevention, diagnosis, and treatment of diseases and conditions that affect the teeth, gums, and other parts of the mouth. This research area examines various aspects of oral health, including dental hygiene, oral diseases, oral microbiology, oral surgery, and oral pathology. Researchers in this field work to improve oral health outcomes, develop new treatments and interventions, and promote public awareness of the importance of good oral hygiene practices. Studies in oral health may also explore the connection between oral health and overall health, as poor oral health has been linked to a range of systemic health issues such as cardiovascular disease and diabetes.
