Which term indicates a condition where a patient has no teeth?

The term "edentulous" specifically refers to a condition in which a patient has lost all of their natural teeth. This medical terminology is derived from Latin roots: "e-" meaning "out" or "without," and "dentulus," which translates to "teeth." Understanding this term is essential in fields such as dentistry and medical documentation, as it helps in accurately describing a patient's oral health status.

In contrast, the other terms provided have different meanings. "Dysphagia" relates to difficulty swallowing; "dyspnea" refers to shortness of breath; and "embolism" describes a condition in which a blood vessel is obstructed by an embolus (a clot or other material that travels through the bloodstream). Each of these terms serves its purpose in different contexts, but they do not pertain to the absence of teeth.
