The Calculus Surface Index is a measure of dental calculus formation. It can be used to quantitate the accumulation of dental calculus in short-term testing programs to evaluate the effectiveness of preventive care.
Method:
(1) Each of the 4 mandibular incisors is assessed on 4 surfaces (one labial, one lingual and two proximal).
(2) Each surface with calculus is scored 1 point.
calculus surface index =
= SUM(calculus points on the 16 surfaces surveyed)
Interpretation
• minimum score: 0
• maximum score: 16
