What does Plaque Index measure?

Explanation:
Plaque Index measures the thickness of plaque at the gingival margin on tooth surfaces. It’s used to assess how much plaque is present as an indicator of oral hygiene, typically scoring multiple surfaces per tooth to reflect overall cleanliness. Higher scores mean more plaque accumulation, helping track changes after hygiene instruction or treatment. It does not measure sulcus depth (that’s probing depth), calculus, or tongue bacteria.
