Which statement is true about gingival recession measurement in GM-CEJ documentation?

• A. It increases with gingival overgrowth
• B. It is measured as the distance from GM to CEJ when gingival margin has receded
• C. It is not related to GM-CEJ
• D. It is measured from CEJ to alveolar crest

Answer: (B)

Gingival recession depth is quantified as the distance from the gingival margin to the cementoenamel junction when the gingival margin has receded apically. As the margin moves downward toward the root, that GM–CEJ distance increases, directly reflecting how far the gingiva has receded. This measure specifically captures recession, whereas gingival overgrowth can obscure or alter the appearance but does not define recession depth, and measuring from CEJ to the alveolar crest would assess bone level, not gingival recession. So the statement that describes recession depth as the distance from GM to CEJ is the correct one.
