Correct answer: D — Recession extending to or beyond the mucogingival junction with interdental bone or soft tissue loss

Miller Class III recession extends to or beyond the mucogingival junction with loss of interproximal bone or soft tissue. Only partial root coverage can be achieved with mucogingival surgery. Class I and II have intact interdental tissues (full coverage possible). Class IV has severe interproximal bone loss (no coverage achievable). The Cairo classification (RT1-RT3) is now preferred in the 2017 AAP/EFP system.
