Two experimental composite resins were placed in the primary molars of 50 children aged 4 to 8 years. Three cavity preparations were used and 357 restorations were placed. The restoratiot~s were evaluated by 2 investigators at 0, 6, 12, and 24 months using the USPH evaluation criteria. At 24 months, 297 (83.1%) restorations were available for recall (48 patients). Discounting restorations lost natural exfoliation (39) the recall rate was 93.4%. There were no statistically significant changes between 0 and 24 months in the 3 preparations or the 2 materials except for the color ma’tch category. Color match deteriorated (p<O.05) significantly in all cavity preparations and for both materials. At 24 months there were no statistically significant differences (p<O.05) between the 2 materials or among the 3 cavity preparations.
