The Green Vermillion index measures...

Tooth mobility
Gingival recession
Periodontal pocket depth
Oral hygiene

The correct answer is: Oral hygiene

The Green Vermillion index measures oral hygiene by calculating the amount of debris and calculus present on the surface of the teeth and measuring the extent of discoloration on the tooth structure. This helps to assess the level of cleanliness and plaque control in the oral cavity. Option A, tooth mobility, refers to the looseness of teeth and is measured with other tools such as dental instruments. Option B, gingival recession, measures the recession of the gum line and is not directly related to oral hygiene. Option C, periodontal pocket depth, measures the depth of the space between the gum and the tooth, which is an indicator of periodontal disease and is not solely related to oral hygiene.
