Abstract :Purpose: This in vitro study compared the effects of mineral trioxide aggregate insert ignore into journalissuearticles values(MTA);, BioAggregate and calcium hydroxide on calcium and hydroxyl ion diffusion through dentinal tubules to the root surfaces without cementum in various root levels. Materials & Methods: The study consisted of 120 mature single-rooted mandibular premolar teeth. The teeth were decoronated and instrumented using Protaper Universal rotary files. To simulate external root resorption, artificial defects were created in cervical-middle-apical thirds of root surfaces. The teeth were divided into four main groups: Control insert ignore into journalissuearticles values(1);, calcium hydroxide insert ignore into journalissuearticles values(2);, MTA insert ignore into journalissuearticles values(3); and BioAggregate insert ignore into journalissuearticles values(4);. In control group, root canals of specimens left empty. Other root canals of specimens filled with calcium hydroxide, MTA or BioAggregate. Each specimen was immersed in a vial containing 10 mL distilled water. Calcium concentrations and pH of the immersion media was measured at 1, 3, 7, 14, 21 and 28 days. Statistical analysis was accomplished by Kruskal–Wallis H and Mann–Whitney-U tests. Results: This study indicated that intracanal placement of both calcium hydroxide, MTA and BioAggregate resulted in the diffusion of calcium and hydroxyl ions across dentine. The results showed greater calcium and hydroxyl ions released by calcium hydroxide groups than MTA and BioAggregate groups insert ignore into journalissuearticles values(p<0.05);. MTA and BioAggregate groups showed similar properties and there were no differences between these groups in whole study period insert ignore into journalissuearticles values(p>0.05);. Conclusion: MTA and BioAggregate may be preferable for external root resorption cases because of their stimulation of hard tissue formation and ion releasing ability.
