A sealant-to-restoration ratio (SRR) has been proposed as a claims-based dental sealant performance measure. A sealant utilization (SU) measure, such as the benchmark established by Healthy People 2000/2010 is often used, but has been criticized for concerns about sealant overuse and interpretation. This research compares information generated by SRR and SU in a population at high risk for dental caries. These population-based measures are defined as: 1) SRR - the number of sealants over the number of restorations; and 2) SU - the percentage of eligibles receiving at least one sealant. Using Medicaid dental claims data (July 1995-June 1996), limited to sealants and restorations on 1st-molar occlusal surfaces in children 5 to 8 years old, we calculated the two measures and their linear correlation for Louisiana’s 64 parishes (counties). We categorized parishes by quartiles of SRR and SU, performed a Fisher’s exact test of association, and identified parishes ranked in the highest and lowest categories by both measures. SU ranged from 0.9% to 21.5% with a mean of 9.6%. These values were well below the Healthy People 2000/2010 objective of 50%. SRR ranged from 0.257 to 13.43 with a mean of 3.695. The measures were correlated (R2=0.65; p<0.0001). The Fisher’s exact test for association between the categorized measures was significant (p<0.0001). Both measures ranked the parishes similarly, agreeing on 12 of the 16 lowest-scoring parishes and 10 of the 16 highest-scoring parishes. For this high-risk population, both measures may yield useful, and similar, information for targeting scarce public health resources.

Learning Objectives: At the conclusion of the session, the participant will be able to:

  1. Define the dental sealant performance measures sealant-to-restoration ratio (SRR) and sealant utilization (SU).
  2. Compare and contrast the behavior and distributions of SRR and SU in populations at high risk of dental caries.
  3. Discuss the potential usefulness of these measures using the information presented.
