StudentRDH Community Health And Research Principles Practice Test

0.1-0.9 indicate what plaque score?

Fair Good Poor Excellent

Correct Answer:

Good

Explanation:

Plaque scoring looks at how much plaque is left on tooth surfaces and expresses it as a decimal range. A value in the range of 0.1 to 0.9 shows that only a small amount of plaque is present on some surfaces, not widespread across the dentition. That level is considered Good because it indicates effective plaque control with room for minor improvement, rather than being completely clean (which would be near 0.0) or having substantial plaque buildup (which would push the score higher toward Fair or Poor). In practice, this range reflects a clean dentition overall with good daily hygiene and brushing/flossing habits.
