Composite resins are the most commonly used material for the restoration of a tooth. The polymerization contraction and the stress associated with it, produce the main cause for failure in a restoration “microfiltration“ OBJECTIVE To compare the microfiltration between a nanorillene resin (Tetric N-Ceram) and bulk resin (Tetric N-Ceram Bulk) in molars with restoration class I, UAC Cusco - 2017 METHODOLOGY The purpose of this study was to compare the microfiltration found in restored dental pieces with a nanohybrid resin and a Bulk resin in class I restorations, Cusco - 2017 UAC The research design corresponded to a descriptive, prospective, comparative and quasi - experimental study. For this purpose, 40 extracted human molar teeth were stored in physiological serum; to which class I cavities were made, the dental pieces were separated into two groups of 20 each; the first group was filled with the Tetric N Ceram nanohybrid resin and the second group with the Bulk Tetric N-Ceram Bulk resin. After a thermocycling process, in the presence of a dye, the pieces were sectioned longitudinally to measure the percentage of microfiltration, using a USB microscope. The analysis of the results showed that the restorations made with the Bulk Tetric N Ceram Bulk resin had lower values of microfiltration, thus there were statistically significant differences between the two study groups.
