How to Use This Calculator
  1. Enter the child's age in months (6–216) to determine the dentition stage and appropriate varnish dose.
  2. Set the Caries risk level (1 = low, 2 = moderate, 3 = high) using the AAPD caries risk assessment tool.
  3. Indicate whether the child has access to Community fluoridated water (0 = No, 1 = Yes) and the number of Active carious lesions currently present.
  4. Review the recommended Application interval in months, Applications per year, and Dose in mL of 5% NaF varnish per visit.
  5. Note the Fluoride per application (mg), Annual fluoride delivered (mg), and Estimated annual cost to support treatment planning and insurance authorization.

What each input means

Child age (months)
Age in months (6 months to 18 years).
Caries risk level
1 = Low, 2 = Moderate, 3 = High (per AAPD caries risk assessment).
Community fluoridated water?
0 = No, 1 = Yes. Absence of fluoridated water increases risk.
Active carious lesions
Number of active white-spot or cavitated lesions currently present.

What each result means

Application interval (months)
Recommended months between fluoride varnish applications.
Applications per year
Expected number of varnish applications per year.
Dose per application (mL)
Volume of 5% NaF varnish per application based on dentition stage.
Fluoride per application (mg)
Milligrams of fluoride ion delivered per application.
Annual fluoride from varnish (mg)
Total fluoride ion delivered from varnish per year.
Estimated annual cost ($)
Approximate annual cost at ~$32 per application (US average).
Composite risk category
1 = Low, 2 = Moderate, 3 = High, 4 = Very High (accounts for lesions and water fluoridation).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Child age (months) = 36, Caries risk level = 1, Community fluoridated water? = 1, Active carious lesions = 0 = 4 input(s) provided
  2. Calculate Application interval
    6 = 6
  3. Calculate Applications per year
    Applications per year
    2 = 2
  4. Calculate Dose per application
    0.25 = 0.25
