%X the purpose of this study was the evaluation in vitro of marginal microleaking, present on gum£¿s edges of class ii cavities of deciduous molars, restored with composite resin (auto and light-cured), with the use of a staining solution to verify the leaking. the prepared cavities presented enamel on gum£¿s edges and were restored according to four different techniques: 1) light-cured composite resin; 2) auto-cured composite resin; 3) mixed technique (auto and light-cured composite resin); and 4) glass-ionomer/composite resin. after the statistical analysis of the results, it was concluded that all the groups presented microleaking, in variable degrees. however, groups 2, 3 and 4 presented the smallest levels of leaking.
