Question: 1 / 1775

What is the definition of a lesion?

A tooth-related infection

An injury or wound; area of diseased tissue

The definition of a lesion is an injury or wound; area of diseased tissue. This term encompasses any abnormal change in tissue, which can result from various causes, including infection, trauma, or disease. In the context of dental terminology, a lesion might refer to any pathological change affecting oral tissues, such as ulcers, sores, or growths, which could be indicative of underlying health issues that need to be addressed.

The other options refer to specific dental situations or tools: a tooth-related infection details a particular condition affecting teeth; a dental cleaning procedure refers to a hygienic practice; and a tool used in dental work points to instruments utilized by dental professionals during procedures. Each of these terms describes different concepts within dentistry but does not capture the broader definition of a lesion as an area of tissue that has been impaired or is diseased.
