Objective: The aim of the present study was to determine whether there is a correlation between fluid infiltration and visible radiographic voids in root filling. Methods: A total of 56 mandibular incisors with straight single canals, complete root formation and no anatomical complexities were selected for this research. Teeth were instrumented by means of Profile System 04 up to file 35 under the same irrigation protocol. Filling was performed by lateral condensation. Subsequently, mesiodistal radiographs were taken for each root and the quality of filling was assessed by calculating the percentage of voids based on the total area. Samples were further assembled into a fluid infiltration set-up. Pearson’s correlation test was used to assess the correlation between fluid infiltration and void areas in root canal fillings. Results: Means and standard deviations of fluid infiltration were 0.311 ± 0.215 μL/min and the percentages of radiographic voids were 7.97% ± 3.93%. Conclusion: No correlation was found between these two variables (P = 0.587). According to the results of this study, the amount of fluid infiltration detected in lower incisors is not influenced by the percentage of radiographically visible voids.
