HOSA Dental Terminology Practice

What is indicated by the distal proximal surface?

1. The surface on the anterior side of a tooth

2. The proximal surface on the posterior side of a tooth

3. The surface closest to the midline

4. The outer surface of the cheek

The correct answer is: The proximal surface on the posterior side of a tooth

The term "distal proximal surface" refers to a specific area of a tooth. In dental terminology, the term "distal" indicates the surface of a tooth that is farthest from the midline of the dental arch, while "proximal" refers to the surfaces of adjacent teeth that face each other. Therefore, the distal proximal surface specifically pertains to the surface of a tooth that is adjacent to the next tooth in the arch and is located on the posterior side of that tooth. This definition is critical in dentistry, especially when considering how teeth relate to each other and how procedures like fillings, crowns, or other restorative work may be performed. Understanding these terms helps dental professionals communicate effectively and ensures that treatment is applied precisely in the correct areas.
