Oral medicine, or stomatology, is the medical study of the mouth and its diseases. It lies at the interface between medicine and dentistry.

Stoma = any opening in the body, such as the mouth. However, stomatology does not deal with any other natural opening of the body. Although the word has a misleading similarity with "stomach", it has nothing to do with the gastrointestinal system. And connective tissue cells of organs are stromal cells, not stomal cells.
