What anatomical feature do incisors possess?

• A. They are cone-shaped
• B. They have multiple cusps
• C. They have a central incisal edge
• D. They are the last teeth to erupt

Answer: (C)

Incisors are characterized by a central incisal edge, which is the flat surface that forms the cutting edge of the tooth. This edge is significant for their primary function, which is to cut food efficiently during the process of chewing. The shape of incisors is generally chisel-like, allowing for the easy slicing of food items. The presence of a central incisal edge also sets them apart from other types of teeth, such as molars, which have multiple cusps for grinding food, and canines, which are more pointed in shape and designed for tearing. Additionally, incisors typically erupt earlier in the dental development sequence, rather than being the last teeth to emerge, solidifying the unique role they play in the dentition.
