--- The physical properties of the composites are very important so the aim of this study was to determine the depth of cure of resins “bulk fill“ photoactivated at different distances. The experimental part was carried out using the ISO 4049 method, cylindrical molds 36 of 4mm diameter and 12 mm in height, in which the resin is placed is produced; 12 samples of each resin (resin A and resin B) were prepared and divided according to the distance of photoactivation (0mm and 4mm) so 6 groups were obtained with 6 resin samples in each group, all were polymerized by LED 10 seconds. Measuring the absolute height of all samples it was performed using a micrometer of 0.01mm accuracy absolute height finally each was divided between 2, which was recorded as the depth of cure of each sample. The data were submitted to the Student t-test for independent samples and ANOVA test with a confidence level of 95%. The results showed that the resin A showed further polymerisation resin B for the two distances photoactivation (0mm and 4mm). The data showed P values <0.05 were statistically significant between the resins evaluated. It was concluded that the depths of polymerization of the resins “bulk fill“ are determined by the distance photoactivation, the resin A has greater depth of cure the resin B. Keywords: depth of cure, composites bulk fill.
