If a patient has 24 teeth and 4 surfaces per tooth, and 24 surfaces show plaque, what is the Plaque Control Record?

Explanation:
Plaque Control Record shows the percentage of tooth surfaces that have plaque. To find it, multiply the number of teeth by the number of surfaces per tooth to get the total possible surfaces, then divide the number of plaque-positive surfaces by that total and multiply by 100. Here, total surfaces = 24 teeth × 4 surfaces = 96. Surfaces with plaque = 24. So PCR = (24 / 96) × 100 = 25%. Thus, the Plaque Control Record is 25%, meaning one-fourth of the surfaces have plaque.
