The edge or cutting edge of an anterior tooth is described by which term?

• A. Incisal
• B. Labial
• C. Lingual
• D. Interproximal

Answer: (A)

Incisal describes the edge used for cutting on the front teeth because these anterior teeth are the ones positioned to bite and slice food. The incisal edge is the sharp border formed on the incisal surfaces of the front teeth, serving as the primary cutting edge. Labial refers to the surface toward the lips, lingual toward the tongue, and interproximal sits between adjacent teeth; these terms describe surfaces or areas rather than the biting edge. So the term that designates the cutting edge of an anterior tooth is incisal.
