【 摘 要 】

Background and aims. The aim of this study was to evaluate the sealing ability of Kryptonite bone cement (Doctors Research Group Inc, Southbury, CT, USA) in retrograde cavities by comparing with Mineral Trioxide Aggregate (MTA) (Dentsply Tulsa Dental Specialties, Tulsa, OK, USA), Amalgam and Intermediate Restorative Material (IRM) (Dentsply Caulk, Milford, DE, USA) using ultrasonic retrograde preparation. Materials and Methods. One hundred extracted single rooted human maxillary incisor teeth were decoronated and the roots were instrumented up to master apical files 40 K file size with Mtwo rotary system and obturated with AH Plus sealer and gutta-percha using cold lateral compaction technique. The specimens were assigned to one control group and four experimental groups according to the retrograde filling materials (n = 20). The specimens were immersed in 0.5% Rhodamine B solution for 48h. Then specimens were split longitudinally into two halves and depth of dye penetration was evaluated under stereomicroscope. Results. There was statistically significant difference between control group and experimental groups (P 0.05). Conclusions. Kryptonite cement provides optimal apical seal as well as MTA, amalgam and IRM when used as retrograde filling cement.
