From multivariable models adjusting for each type of material (number of surfaces currently treated with sealant/preventive resin restoration, compomer, or composite), age, time from baseline visit, study site, baseline blood lead level, and parent-reported asthma or allergy.
Flowable composite was used for sealants on sound surfaces and for preventive resin restorations on shallow decay. Non-flowable UDMA-based compomer (polyacid-modified composite) was used for primary tooth restorations. Non-flowable standard bisGMA-based minifill composite was used for permanent tooth restorations. Materials were not used exclusively in each child; most children received treatment with more than one type of resin-composite.
Among children with that type of resin-composite material present in the mouth at that time point, the mean ± standard deviation number of composite-treated surfaces present.
P<0.05.
