Oral medicine is a specialty of dentistry that focuses on the diagnosis, management, and treatment of oral and maxillofacial diseases and disorders that affect the mouth, jaws, and related structures. 

Oral medicine practitioners are trained in identifying and treating various conditions, including oral infections, oral cancer, mucosal diseases, salivary gland disorders, and oral manifestations of systemic diseases. They may work in close collaboration with other medical and dental specialists, such as oncologists, rheumatologists, and dermatologists, to ensure comprehensive patient care.

Some of the common procedures and techniques used in oral medicine include clinical examination, biopsy, imaging tests, laboratory tests, and pharmacological therapies.
