Which term refers to dental pain?

The term that refers to dental pain is "dentalgia." This word is derived from the roots "dent-" meaning tooth and "-algia" meaning pain. Therefore, it directly describes the experience of pain associated with the teeth. Understanding medical terminology often involves breaking down these components, which can provide clarity on what a term signifies in a clinical context.

The other terms mentioned do not relate to dental pain. "Corneal injection" refers to the redness of the eye due to inflammation of the conjunctiva or the eye's surface, which is unrelated to dental issues. "Anisocoria" describes a condition in which the pupils are unequal in size, and "nystagmus" refers to involuntary eye movements, typically indicating neurological issues. Recognizing these distinct definitions helps to confirm why "dentalgia" is indeed the appropriate answer for dental pain.
