Dentistry · Caries, pulp and periodontal disease: Miller classification of recession

Sample item

A patient has gingival recession on a mandibular canine that extends beyond the mucogingival junction. There is no loss of interdental bone or soft tissue. Which Miller class is this?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Class II

Miller Class I recession does not reach the mucogingival junction, Class II reaches or extends beyond it, and in both there is no interdental loss. Class III has interdental loss or malposition and Class IV has severe loss. Complete root coverage is predictable in Classes I and II.

Option by option

  • A. Class I

    Class I stops short of the mucogingival junction.

  • B. Class IV

    Class IV has severe interdental loss and malposition.

  • C. Class II (correct)

    Correct. Recession reaching beyond the junction with intact interdental tissue is Class II.

  • D. Class III

    Class III includes loss of interdental bone or soft tissue.
