What is the scoring for the plaque index?

• A. 0 = No plaque
• B. 1 = Plaque detected by probe
• C. 2 = Moderate plaque seen with eye
• D. 3 = Heavy plaque covering the entire area

Answer: (A)

In plaque index scoring, each tooth surface is rated on a scale where zero means no plaque is present. This establishes a baseline: a clean surface gets a score of zero, while any detectable plaque pushes the score up to 1, 2, or 3 depending on how much plaque is present. The option stating zero equals no plaque is the correct emphasis because it defines the starting point of the scale. As a student, you’ll use this zero when evaluating cleanliness and tracking changes over time; the higher numbers simply indicate increasing amounts of plaque. While other descriptors (plaque detectable by probe, visible plaque to the naked eye, heavy plaque) describe higher levels, the essential scoring rule begins with zero for no plaque.
