Agitation

1. the shaking of a substance, either for mixing ingredients or to remove debris or buildup from an object within the substance, such as a removable oral prosthetic.
2. the intentional, usually mild, disturbance of the skin, mucosa, or other surface (e.g., with a wooden interdental cleaner or probe instrument) to determine if infection or disease is present. If agitated surfaces bruise or bleed easily, or are otherwise disrupted (e.g., develop a lesion), the presence of a pathologic condition should be suspected.
3. a psychosomatic condition represented by uncontrollable or excessive body movements. The psychologic aspect may often indicate the presence of unresolved stress.
