Classification Systems of Gingival Recession: An Update

Abstract

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. With a wide array of cases in daily clinical practice, it is often difficult to classify numerous gingival recession cases according to defined criteria of the present classification systems. This article outlines the limitations of present classification systems and also the new classifications that have been proposed to classify gingival recession.
