In a Class V preparation, what is the term for the incisal wall of an incisor?

A Class V preparation typically involves the area of a tooth that is located at the gingival third of the facial and lingual surfaces. In the context of an incisor, the term that refers specifically to the wall created at the incisal edge is indeed known as the incisal wall, which corresponds most closely to the occlusal surface in terms of terminology relevant to the orientation of the tooth.

While "buccal wall," "lateral wall," and "pulpal wall" describe different aspects or surfaces of a tooth preparation, the incisal edge itself acts similarly to the occlusal surface on posterior teeth due to its functional role in occlusion and aesthetics, as it is related to the biting surface. Therefore, choosing the term "occlusal surface" acknowledges that in the context of an incisor, the incisal edge serves a similar purpose and position as the occlusal surfaces of molars and premolars in this type of preparation.
