What tool is used to access the Plaque Index score?

• A. Mirror
• B. Probe
• C. Ruler
• D. Dental Explorer

Answer: (B)

Accessing the Plaque Index relies on detecting whether plaque is present on tooth surfaces and how much covers each surface. A periodontal probe is used because it allows gentle tactile assessment along the tooth and under the gumline, letting you feel and map where plaque is located and how extensively it covers each area. This tactile probing is essential for scoring the index consistently across surfaces. A mirror helps with visibility, but it doesn’t provide the information about plaque presence by touch. A ruler isn’t used for evaluating plaque; it’s for measuring dimensions, not surface contamination. A dental explorer can detect calculus and irregularities but is more invasive and can disrupt plaque boundaries, making it less suitable for standardized plaque scoring.
