- The removal of a foreign material, such as calculus or plaque, or removal of necrotic (dead) tissue from or adjacent to a lesion. Very commonly this term is used for a goal in nonsurgical periodontal instrumentation.

- Of or toward the tongue, to identify the surface of a tooth that faces the tongue.
