Inadequate apical seal is a major cause of surgical endodontic failure. The root end filling material used after apicectomy should adhere or bond to tooth tissue and seal the root-end three-dimensionally. Aim of this study was to evaluate the sealing ability of modified (bioactive) bone cement, Mineral trioxide aggregate and glass ionomer cement when used as root end filing materials.
Materials and Methods: Thirty human maxillary central incisor teeth were prepared and obturated using gutta percha and AH Plus sealer. After 24 hours, apical 3mm was removed from each tooth and root end cavities made with ultrasonic tips. Samples were randomly divided into three groups of 10 samples each based on root end filling material - Group I: MTA, Group II: Bioactive Bone Cement and Group III: Glass Ionomer Cement. After one week of storage in PBS solution, specimens were subjected to dye extraction analysis and amount of dye absorbed was calculated in terms of absorption units using UV-Visible light spectrophotometer.
Results: Results showed that samples back filled with Bioactive bone cement had absorbed lowest dye (0.69±0.078 AU) followed by samples filled with MTA (0.72±0.108 AU). Highest dye absorption values were shown by samples filled with glass ionomer cement (1.53±0.200 AU). Statistical analysis showed no significant difference between Bioactive Bone cement group and MTA group (P =0.872) while as significant difference existed between these two and Glass ionomer group (P<0.001).
Conclusion: Bioactive bone cement is a viable alternative to currently used materials with ease of use and cost effectiveness as shown by low microleakage values when used as root end filling material.
