<dc:description>Aim:The aim of this study was to compare the sealing ability of biodentine with mineral trioxide aggregate (MTA) by dye leakage testusingmethylene blue. Materials and methods:thirty human single-rooted teeth wereprepared and the canals were instrumented using standard method up to # 40, andobturated with gutta-percha and zinc oxide. The ends of the roots were resected at 3 mm away from the apices, and the retrograde cavities were prepared using fissure bur. The teeth were divided into two groups (n=15 for each group); first group was filled with MTA, and the second with Biodentine. The teeth immersed in the methylene blue 2% for 24 hours. Then the teeth were cut longitudinally and the dye leakage was measured in millimeter under the stereoscope. Results:There was no statistically significant difference between the two groups from the way of sealing ability (P &gt; 0.05). Conclusion:Under the conditions of this study: it could be concluded that Biodentine has the same apical sealing ability compared with MTA when it used as a retrograde filling material.</dc:description>
