    The aim of this research was to determine the degree of marginal microleakage in premolar teeth using two provisional filling materials (Coltosol F® and Zinc Oxide and Eugenol). Methodology: A hypothetical-deductive study was developed, with an applied type, comparative level, quantitative approach, and experimental design. The sample consisted of 30 human teeth on which class II cavity preparations (occluso-proximal) were made. The samples were randomly divided into two groups: N=15, and the provisional restorative material (Coltosol F® and Zinc Oxide and Eugenol) was applied. Different types of cuts (sagittal, frontal, coronal) were made to evaluate all the walls involved in this investigation. Measurements were taken with a 10x optical microscope, and the images were adjusted to real scale using Adobe Photoshop CS6 and Adobe Illustrator CS6. Results: For the sagittal plane cut and its four respective microleakage degrees, it was found that Coltosol F® had 60% SF samples and Zinc Oxide and Eugenol had 47% FM samples. For the coronal plane cut and its four respective microleakage degrees, it showed that Coltosol F® had 67% SF samples and Zinc Oxide and Eugenol had 53% FM samples. For the frontal plane cut and its four respective microleakage degrees, it showed that Coltosol F® had 33% SF samples and Zinc Oxide and Eugenol had 67% FM samples. Conclusion: Coltosol F® exhibited a lower degree of microleakage than Zinc Oxide and Eugenol.
