1.0-1.9 indicate what plaque score?

Fair Good Poor Excellent

Correct Answer:

Fair

Explanation:

In plaque scoring, you average the plaque scores across the examined tooth surfaces to get a mean plaque score. This mean is then interpreted using descriptive ranges to describe the level of plaque control: lower numbers mean cleaner surfaces, higher numbers mean more plaque. A mean in the 1.0 to 1.9 range reflects more plaque than the ideal (0) and more than what would be considered good, but not enough to be labeled poor. That middle-ground level is described as Fair, indicating a moderate amount of plaque that suggests room for improvement in plaque control techniques. So, 1.0–1.9 fits the Fair category.
