Which of the following results indicates a normal jaw examination?

A normal jaw examination is characterized by the absence of any abnormal findings, which includes no swelling, tenderness, pain, or limitations in movement of the jaw. When a healthcare provider assesses the jaw, they are looking for a range of normal behaviors, such as the ability to open and close the mouth without discomfort and without any visible abnormalities.

Marked swelling typically indicates inflammation or an underlying pathology, while tenderness or pain usually suggests some form of injury or disorder affecting the jaw. Limited movement can be an indication of conditions such as temporomandibular joint dysfunction or arthritis, which are not considered normal. Therefore, the presence of these signs would suggest that there is an issue that needs to be investigated further, while the absence of any such findings confirms that the jaw is functioning normally.
