The composite resins have been widely used in Pediatric Dentistry, because they preserve the health dental structure, are more esthetics and their abrasion level is similar that of the deciduous teeth. Objectives: to evaluate the behavior and the longevity of the composite resins fillings in posterior deciduous teeth using the USPHS and FDI methods. Materials and methods: 09 children were selected who had 34 restorations (occlusal and occlusoproximal) in primary molars performed by undergraduate students of Lutheran University of Brazil Cachoeira do Sul/RS with Charisma®, FiltekT P60, FiltekT Z250 XT composite resins). The restorations were evaluated by an examiner blinded to the study objectives, through USPHS and FDI methods criteria. Statistical analysis was performed by the Kruskal-Wallis test, with the significance level set at 5%. Results: the 3 composite resins did not show any difference regarding to majority of criteria employed in the two methods. For the superficial staining criterion there was statistically significant difference among the composite resins (p=0,006), being Filtek P60 the resin that showed worst superficial staining than Charisma and Filtek Z250. Conclusions: the composite resins evaluated were satisfactory and available to fill deciduous teeth. The composite resins Charisma and Filtek Z250 showed better performance than Filtek P60 in relation to superficial staining criterion. The two evaluation methods can be used to evaluate restorative procedures in deciduous teeth, being FDI method the most complete and promising though.
