The correct answer is: Nearest or immediately adjacent to

The term 'proximal' in dentistry refers to the surfaces of the teeth that are nearest or immediately adjacent to each other. This is particularly important in understanding tooth anatomy and positioning because proximal surfaces are where adjacent teeth come into contact. In practical terms, when discussing cavity preparation, restorations, or periodontal issues, identifying the proximal surface helps in assessing how much of the tooth structure is involved and how to effectively treat it. The concept of 'proximal' is typically associated with the mesial (closest to the center of the dental arch) and distal (farthest from the center) areas of adjacent teeth. Understanding this term is crucial for dental professionals when planning treatments and for communicating accurately about dental conditions.
