==Medical language is an extended natural language==
Language is a source of misunderstandings and errors and in medicine: actually, often the language we use leaves us in trouble because it is semantically underdeveloped and does not agree with standard scientific ideas. To better explain this concept, which apparently seems off-topic, we must describe some essential characteristics of the logic of language that will make us better understand why a term like ''orofacial pain'' can take on a different meaning following a classical logic or a formal one.

Little is known about how experienced doctors understand this phenomenon, and about how they work with it in clinical practice.
