Correct answer: D — Moderate accumulation of plaque visible to the naked eye within the gingival pocket or at the gingival margin

The Silness and Löe Plaque Index (1964): 0 = no plaque; 1 = thin film of plaque at the gingival margin detected only by scraping with probe tip; 2 = moderate accumulation of plaque visible to the naked eye at the gingival margin and/or within the gingival pocket; 3 = abundance of plaque filling the interdental embrasure (heavy accumulation). This index does not use a disclosing agent and assesses plaque thickness and extent. It is widely used in clinical research to evaluate oral hygiene interventions.
