Which condition is associated with involuntary muscle contractions of the jaw?

Aphasia
Trismus
Aphagia
Callus

The correct answer is: Trismus

Trismus, also known as lockjaw, is a condition characterized by the involuntary contraction of the muscles of mastication, which are responsible for the movement of the jaw. This involuntary muscle contraction leads to restricted jaw movement, making it difficult for an individual to open their mouth. Trismus can occur for various reasons, such as after dental surgery, due to certain medical conditions, or as a side effect of radiation therapy for head and neck cancers. Understanding trismus is important for dental professionals as it can affect patient care, including the ability to conduct dental procedures and overall oral health. Other options like aphasia and aphagia relate more to conditions affecting speech and swallowing, while a callus refers to thickened skin resulting from friction or pressure, which does not pertain to jaw function.
