a Gingival recession is measured clinically as the distance in millimeters from the CEJ to the free gingival margin using a periodontal probe. b Clinical crown height is a measure from the cusp tip or incisal edge to the depth of the gingival sulcus. Attrition (long dash of horizontal line) will shorten this measure. c Gingival margin-papillae measure is the shortest apico-coronal distance measured from the depth of the gingival margin to a line connecting the tips of the two adjacent papillae.
