What is indicated by a plaque index range of 2.0-3.0?

Excellent
Poor
Good
Fair

The correct answer is: Poor

A plaque index range of 2.0-3.0 indicates a poor level of oral hygiene. This scoring system typically uses a scale where lower scores represent better plaque control and higher scores indicate increasing levels of plaque accumulation. A range from 2.0 to 3.0 suggests that there is a moderate amount of plaque present on the teeth, which may lead to an increased risk of dental problems like gingivitis or cavities if not addressed. Therefore, this range reflects a need for improved oral hygiene practices to reduce plaque build-up and enhance overall dental health.
