Zone 2 corresponds to which surface?

Explanation:
Understanding how surfaces are labeled in periodontal charting helps you map zones to the correct tooth surface. Zone 2 refers to the facial surface, the outward-facing side toward the lips or cheeks. This is the broad surface analyzed in many PSR/probing records. The lingual surface faces the tongue, so it doesn’t fit Zone 2. The other options describe more specific portions of the facial surface, near the mesial or distal edges (mesiolabial or distofacial), which are not the general zone being asked about. So the facial surface is the correct match for Zone 2.
