Özet: Background: The current recommendations for the apical preparation diameter, one of the most important mechanical imperatives in the apical third preparation is to preserve the apical foramen in its original position along with its narrowest diameter in order to avoid any complication such as tearing, zipping, or transport of the foramen. Objectives: The aim of our study is see the correlation between apical seal and apical preparation diameter. Methodology: Freshly extracted 90 central incisors were selected and they were randomly allocated into 3 experimental groups of 30 teeth each. Group 1: Canals were prepared up to size 20 corresponding by Coltene Hyflex rotary system coinciding F1. Group 2: Canals were prepared up to size 30 by Coltene Hyflex rotary system coinciding F3. Group 3: Canals were prepared up to size 50 by Coltene Hyflex rotary system coinciding F5. After the filing of the root canals, the teeth were isolated and immersed in a dye solution, then cut longitudinally, photographed, and the dye penetration were calculated using a computer software. Results: The comparison of three different apical preparation sizes showed no statistically significant differences regarding the apical microleakage. Conclusion: The most important value of the dye penetration was observed in the group with the largest apical diameter.
