What teeth are used in the teeth cleanliness index?
- Buccal surfaces
- 46 - Lingual surfaces

Plaque 1mm wide at margin
What is 4/10 score for teeth cleanliness index?
up to 1/3 tooth covered with plaque
What is 2/10 score for teeth cleanliness index?
up to 2/3 tooth covered in plaque
What is 0/10 score for teeth cleanliness index?
more than 2/3 covered in plaque
What is the Silness and Loe Plaque Index?
The measurement of oral hygiene based on the soft debris and mineralised deposits . Each surface on the tooth is given a score 0-3.
How is Silness and Loe score worked out?
The scores for each surface of the tooth are added and then divided by 4.
In silliness and Loe, what does a score of 0 mean?
No plaque
