The main objective of this study is to determine the differences of microfiltration in inlays made in resins, cemented with thermos modified resins and cemented with dual cement. The study is a pre-experimental in vitro, longitudinal and quantitative approach. The sample consisted of thirty (30) upper and lower permanent human molar teeth which were extracted for therapeutic reasons at the Luis Vallejos Santoni Stomatological Clinic of the Andean University of Cusco and private offices, which had a cavity for mesio-occlusal inlay. Then the sample was divided into two groups of 15 study units and the dental resins inlays were cemented with Herculite Kerr Thermo modified Resin and Variolink Ivoclar Vivadent Dual Resin. Finally, both groups were immersed in 0.5% methylene blue solution for up to 48 hours to evaluate microfiltration. As results, microfiltration was obtained with different degrees: in the case of thermo modified resins, 66.7% of the sample presented some degree of microfiltration; in the case of the sample with dual resin, 100% presented microfiltration. The microleakage according to the time elapsed in inlays cemented with dual cement increased from an average of 0.27mm at 12 hours, 1.07mm at 24 hours, 1.80mm at 36 hours and 2mm at 48 hours. The microleakage according to the elapsed time in inlays cemented with thermo modified resin did not present any case of microleakage at 12 hours of analysis, increasing from an average of 0.27mm at 24 hours, 0.53mm at 36 hours and 0.80mm at 48 hours. The comparison of microleakage according to the elapsed time of the inlays cemented with dual cement and cemented with thermo modified resin was also observed. The statistical test showed differences in the microleakage of each of the cements at 12 hours (p=0.035), 24 hours (p=0.005), 36 hours (p=0.000) and 48 hours (p=0.007), in all with a value of p<0.05. Finally, to the statistical test of Chi square and Fisher's exact test (p<0.05), if there are statistically significant differences with a lower microleakage in the sample of the thermo modified resins over the sample with dual resin in the study groups.
