Miller class iv

Which Miller class is associated with marginal tissue recession extending to the mucogingival junction but having absolutely no loss of interdental bone or soft tissue?

Miller class ii

Why might a clinician find it difficult to distinguish between a Miller class iii and a Miller class iv recession?
