Which term describes the surfaces located between adjacent teeth?

• A. Proximal
• B. Inter-proximal
• C. Mesial
• D. Distal

Answer: (B)

Interproximal surfaces describe the sides of teeth that face the neighboring tooth and the space between them. The term interproximal specifically denotes the region located between adjacent teeth, making it the best fit for surfaces found in that between-teeth area. Proximal surfaces refer to a tooth’s surface toward its neighbor, but the emphasis here is on the location between teeth, which is captured by interproximal. Mesial and distal are directional terms toward or away from the midline, not the between-teeth surfaces. So the term describing surfaces located between adjacent teeth is interproximal.
