HOSA Dental Terminology Practice

What does the term "incisal" refer to?

1. The surface of the tooth facing the tongue

2. The biting edges of the incisor and cuspid teeth

3. The area between adjacent teeth

4. The front area of the dental arch

The correct answer is: The biting edges of the incisor and cuspid teeth

The term "incisal" specifically refers to the biting edges of the incisor and cuspid teeth. Incisal edges are the sharp, cutting surfaces found on the anterior teeth, which include the incisors (the front four teeth) and canines (cuspid teeth). These edges play a crucial role in the proper functioning of the mouth, as they are primarily involved in the biting and cutting of food. Understanding this term is essential in dental terminology, as it helps professionals accurately describe dental anatomy and communicate effectively about various dental procedures and treatments related to the front teeth. The other options describe different aspects of dental anatomy, such as tooth surfaces and positioning, but do not pertain to the specific function and location associated with the term "incisal."
