Classification systems of gingival recession: An update

Gingival recession is defined as “the displacement of marginal tissue apical to the cementoenamel junction (CEJ)”. Various classifications have been proposed to classify gingival recession. Miller's classification of gingival recession is most widely followed.

This article outlines the limitations of present classification systems and also the new classifications that have been proposed to classify gingival recession.
