Oedema is the correct term for which of the following?

Oedema refers specifically to swelling caused by the accumulation of fluid in the tissues. This medical condition can occur in various parts of the body and can result from a variety of causes, such as injury, inflammation, or underlying health issues. Understanding oedema is important for dental nursing as it can manifest in the oral cavity, potentially indicating underlying health concerns or reactions to treatments.

The other terms provided have distinct meanings. Infection refers to the invasion of the body by harmful microorganisms, leading to illness. Inflammation is a broader response to injury or infection characterized by redness, heat, swelling, and pain. Redness is a specific sign often associated with inflammation, but it does not encompass the fluid accumulation that oedema indicates. Recognizing the differences among these terms is essential for effective patient evaluation and care in dental practice.
