Zone 3 corresponds to which surface?

Explanation:
In PSR probing, zones map to specific surfaces around a tooth, helping you quickly record findings by location. Zone 3 corresponds to the surface between the mesial and facial directions, which is the mesiofacial surface. That’s why the correct surface designation for zone 3 is mesiofacial (MF). It’s different from a pure facial surface (F) or surfaces like mesiolingual (ML) or distolingual (DL), which align with other zones.
