What is the difference between dentistry & stomatology?

Varying opinions: Stomatology is a medical discipline which concerns the study of the mouth. Historically it was a recognized medical specialty in many regions of the world, although today people are more likely to refer to stomatology as “dental medicine,” depending on where they are located. In some countries, it is still possible to specialize in stomatology as a discipline separate from dentistry.

Dentistry: dentistry is the care of the teeth and surrounding structures. Stomatology treats the soft tissues of the mouth.

Similar/Different: Stomatology refers to the study, diagnosis, and treatment of conditions and diseases of the mouth and it's associated structures. It's not a specialty in medicine or dentistry, and different kinds of practitioners can work in that field. Dentistry also has a component of stomatology, but its primary focus is more on the teeth and their supporting structures. So, different but similar disciplines.
