Pit-and-fissure sealants on primary molars are a cost savings.

Background: In this study, the authors examine the cost-effectiveness of light-polymerized resin-based fluoride sealants on primary molars in high caries risk children younger than 6 years.

Methods: The authors examined the cost-effectiveness of pit-and-fissure sealant (PFS) treatment on primary molars by comparing sealed and unsealed molars treated in the outpatient clinic or operating room. Using 1,884 primary molars followed over a 5-year period, the authors used a mixed-effects regression model to estimate the probability of caries development.
