The aim of this study was to evaluate the one-year clinical performance of a polyacid-modified resin composite material (Dyract) in comparison to a composite resin material (Helioseal F). Methods: Using a half-mouth design, 100 sealants were placed on the sound first permanent molars of 50 children aged between six and 10 years. Half of the teeth (n = 50) were sealed with Dyract and half (n = 50) with Helioseal F. Teeth were evaluated at baseline, 3, 6 and 12 month intervals. The qualities of the restorations were evaluated in accordance with modified U.S. Public Health Service (USPHS) codes and WHO criteria for the presence of dental caries. The data were analyzed according to the Mann-Whitney test and the spearman correlation. Results: There were no statistical differences between the two examined groups, considering marginal integrity, retention and caries. There also appeared to be no statistical difference between the standards in different ages (six-eight years and eight-ten years) and the two arches (P > 0.05). Decayed/Missing/Filled Teeth index (DMFT) had convert relation with retention and marginal integrity in both materials. Conclusion: In this study there was no clinical difference between the two sealants. Polyacid Modified Resin Composite (PMRC) materials have low wear resistance compared to resin composite, but the two curing reactions that occur in PMRC materials might have improved their mechanical retention in the long term. Therefore, further study on these characteristics is recommended.
