Results

Estimated Retention Rate

76%

Expected Lifespan

5.5 years

Reapply RecommendationNo — monitor at recall
How to Use This Calculator
  1. Enter Tooth Type, Molar, and Premolar.
  2. Set Patient Age at Placement, Years Since Placement, and Material Type.
  3. Adjust Resin-Based, Glass Ionomer as needed.
  4. Review Estimated Retention Rate (%) and Expected Lifespan (years).
  5. Use Reapply Recommendation to inform your decision.

What each input means

Tooth Type
Molars have deeper pits/fissures and slightly lower sealant retention
Patient Age at Placement
Age when sealant was placed; younger patients may have lower retention
Years Since Placement
How many years ago the sealant was placed
Material Type
Resin-based sealants have higher retention; glass ionomer releases fluoride

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Tooth Type = 1, Patient Age at Placement = 8, Years Since Placement = 2, Material Type = 1 = 4 input(s) provided
  2. Calculate Estimated Retention Rate
    Estimated Retention Rate
    76 = 76%
  3. Calculate Expected Lifespan
    Expected Lifespan
    5.5 = 5.5
